A sex toy sample approval checklist should turn a visual impression into a documented production decision. Before an OEM or ODM product moves into mass production, the buyer and factory need written acceptance criteria, named test owners, traceable evidence, and untouched reference units. “Looks good” is not an approval record.
This guide covers 15 practical checks for material, finish, function, power, water resistance, durability, packaging, and documentation. Some checks are buyer reviews, some require factory or laboratory equipment, and some must be handled by a qualified third party. The objective is not to make every buyer a test laboratory; it is to make responsibilities and evidence clear before bulk production begins.
Use the sex toy sample approval checklist consistently across engineering, pilot, and pre-production revisions so that every change is evaluated against the same acceptance baseline.
Important: This checklist supports sample approval. It does not replace product risk assessment, regulatory advice, or qualified laboratory testing.
Never perform lithium-battery abuse tests yourself, never charge a wet product, and reserve separate units for drop, immersion, and life-cycle testing.
Who Should Use This Sex Toy Sample Approval Checklist?
This acceptance guide is designed for brand owners, importers, sourcing teams, quality engineers, and production approvers working with a sex toy manufacturer. It is most useful after the concept and commercial direction have been agreed, when a sample must be accepted, corrected, or rejected before the factory books the bulk run.
The checklist should travel with the product specification. For a new project, begin by defining the product category, target market, material, electrical configuration, claimed water-resistance level, packaging, and applicable compliance route. WINYI’s OEM and ODM manufacturing services explain where sample review fits within the wider development process.
Confirm the Sample Stage, Revision, and Unit Allocation
Identify the sample stage before testing
An engineering sample is often hand-finished from an early tool and primarily demonstrates design intent. A pilot sample comes from an initial production exercise. A pre-production sample uses the intended tooling, materials, assembly route, and line conditions, so it gives the strongest prediction of bulk output. Approving a hand-finished engineering piece and expecting normal line production to match it exactly is a common source of disagreement.
Record the model code, drawing and BOM revision, firmware and app version, colour reference, packaging revision, serial number, receipt date, and test date. A change to a critical component, material, firmware function, claimed rating, or packaging structure should trigger reassessment rather than informal approval.
Reserve untouched and destructive-test units
Allocate units before the first check. Keep at least two untouched units for sealed Golden Samples, one held by each party. Use separately identified units for drop, immersion, button-life, extended run-time, and other potentially destructive or accelerated tests. A unit that has been dropped, immersed, dismantled, or subjected to life cycling cannot later serve as the appearance and function reference.
Who Runs Each Sample Approval Test?
Each test belongs to one of three evidence tiers. The tier determines what the buyer should review or request, not what the buyer should try to reproduce without the correct equipment.
- Buyer review: non-destructive appearance, operation, documentation, and basic comparison checks that can be photographed and recorded.
- Factory or laboratory verification: checks requiring calibrated instruments, fixtures, controlled conditions, or defined cycle counts.
- Third-party compliance testing: market- and configuration-specific assessment conducted by a qualified laboratory. A factory checklist cannot replace it.
Ask for the result, method, conditions, unit serial number, and report date. A photograph of equipment proves only that the equipment exists; it does not prove that your model passed a defined test. WINYI’s in-house laboratory overview shows the types of equipment available for product validation.
Tests 1-5: Material, Colour, and Finish
Fix the conditions before judging material identity or appearance. Subjective words such as “soft,” “perfect colour,” or “no smell” are difficult to enforce unless the specification names the reference, method, viewing conditions, and acceptance limit. A signed sample supports the written requirement but should not replace it.
| # | Test | Owner | Specification to agree in writing | Evidence to retain |
|---|---|---|---|---|
| 1 | Material identity | Factory, third party | Material, grade, formulation, lot, supplier and BOM traceability, plus a change-control rule | Declaration, CoA and reports tied to the lot, not only the grade |
| 2 | Hardness | Factory | Full Shore scale and method, standard plaque or named test point, conditioning, and tolerance | Instrument reading plus a signed tactile sample |
| 3 | Colour | Buyer, factory | Agreed illuminant, lux, viewing distance and angle, plus limit samples; if numerical, name the instrument, formula and limit | Photographs against limit samples or the measured value |
| 4 | Surface finish | Buyer | Named defects, consistent viewing conditions, and accept/reject limit samples | Photographs of every flagged area |
| 5 | Odour | Buyer | Whether odour is perceptible unpackaged and again after 24 hours boxed | Written finding with the box and liner identified |
Do not over-interpret these checks. A declaration and grade report do not by themselves prove finished-product identity or suitability. Hardness must include the scale; very soft silicone or TPE may require a different scale, while curvature, thin walls, and rigid internal parts can affect finished-part readings. Odour and feel cannot substantiate claims such as “body-safe,” “medical-grade,” or “non-toxic.”
At this stage, the sex toy sample approval checklist should connect every material and appearance result to the exact lot, revision, signed limit sample, and acceptance record.
Tests 6-10: Function, Power, and Noise
Run power checks with the specified cable on a ventilated, non-combustible surface and stop if you notice swelling, leakage, unusual odour, or abnormal heat. Never intentionally short-circuit, puncture, overcharge, or deeply discharge a lithium battery.
| # | Test | Owner | Specification to agree in writing | Evidence to retain |
|---|---|---|---|---|
| 6 | Vibration output | Buyer | Perceptible steps between levels, no dead level, and how units are compared | Recorded result for every unit and serial |
| 7 | Modes and controls | Buyer | Complete mode set and sequence as printed in the manual, plus memory behaviour | Result for each mode against the manual |
| 8 | Noise | Factory | Instrument, distance, support surface, setting, and limit, measured consistently | Measured value with all conditions stated |
| 9 | Battery run time | Buyer, factory | Setting, starting state, ambient temperature, and timing method | Timed result for every unit with method recorded |
| 10 | Charging | Buyer | Charge time from normal low-battery cutoff, port fit, cable retention, and indicator states | Timed result and indicator photographs |
Test 9 describes how the finished sample performed; it does not establish cell safety or transport compliance. For a rechargeable product, request the UN 38.3 test summary that matches the battery and product configuration. The UN Manual of Tests and Criteria contains the relevant transport-test framework. Confirm with a qualified professional whether IEC 62133-2 or other battery evidence applies to the intended market and customer.
Add a separate module for app-controlled products
For an app-controlled toy, add pairing time, reconnection after signal loss, permissions requested, account deletion, privacy notice, firmware version, and recovery from a failed update. Wireless, privacy, and cybersecurity requirements are market-specific and are not proven by a functional bench check.
Tests 11-13: Water Resistance, Drop, and Button Life
These are destructive or accelerated tests. Assign dedicated units and do not retain them as Golden Samples. Agree the exact procedure and acceptance criterion before testing; casual demonstrations are not substitutes for controlled evidence.
| # | Test | Owner | Specification to agree in writing | Evidence to retain |
|---|---|---|---|---|
| 11 | Water resistance | Third party, laboratory | IEC 60529 edition, report conditions, sample state, port and cap position, and acceptance method | Laboratory report for the exact configuration |
| 12 | Drop | Factory, laboratory | Height, orientation, surface, drop count, unit count, and pass criteria | Report plus photographs of each unit |
| 13 | Button life | Factory, laboratory | Cycle count, actuation-force tolerance, unit count, and pass definition | Report with force and cycle records |
An IP rating describes a defined test on a defined configuration under the IEC 60529 IP Code. It is not automatically a promise about showers, baths, prolonged immersion, or warranty coverage. Confirm which rating applies to the actual model and what the instructions exclude. After an immersion test, do not charge the unit until it is fully dry and confirmed safe under its instructions.
Tests 14-15: Packaging and Documentation
Test 14 covers the fully packed unit, accessories, artwork, and packaged drop procedure. Test 15 covers labels, manuals, warnings, traceability, and market documentation. A finished product should not be approved while its box, barcode, or instructions are still placeholders.
| # | Test | Owner | Specification to agree in writing | Evidence to retain |
|---|---|---|---|---|
| 14 | Packaging, accessories, and packed drop | Buyer, laboratory | Structure, print against approved artwork, insert fit, packing list, and the named ISTA, retailer, or carrier drop procedure | Photographs, packing-list sign-off, and drop report |
| 15 | Labelling and documentation | Buyer, third party | Barcode resolves to the buyer’s GTIN; manual language, warnings, model, batch marking, and market labels are correct | Scan record and approved artwork revision |
Scan the physical barcode with a real scanner and confirm it resolves to the intended GTIN. Labelling rules vary by market and product type, so confirm the current requirements with a qualified compliance professional. WINYI’s sex toy certification overview outlines common testing and documentation routes, but the final route must match your product and destination market.
Build the Golden Sample, Limit Samples, and AQL Plan
A Golden Sample cannot carry the entire quality standard by itself. The production baseline consists of four connected records: sealed Golden Samples, a written specification, defect limit samples, and revision-controlled test evidence.
Your completed sex toy sample approval checklist becomes the index that links these records and shows which evidence supports each approval decision.
- Complete all 15 checks. Record the agreed specification and actual result against each item, including dates, serial numbers, and photographs.
- Issue one numbered correction list. State the current condition, required condition, owner, and verification method for every correction.
- Define the re-sample rule. State which corrections require a new sample and which may be checked at the first article before the production line continues.
- Sign and seal two untouched units. Add the model, revision, date, correction-list reference, storage conditions, and validity period.
- Agree the sampling plan. Define lot size, inspection level, code letter, sample size, critical/major/minor defect classes, AQL values, and accept/reject numbers.
- Book the production inspection. Agree who inspects, when inspection occurs, and which evidence is required before shipment.
The current edition, ISO 2859-1:2026, provides sampling procedures for inspection by attributes. An AQL is a sampling rule, not permission to ship known defective units. Structural or irreversible problems should be controlled earlier in production rather than left for a final pre-shipment check.
What Goes on the Sample Correction List?
Use one controlled document instead of spreading changes across messages. Give each correction a number and include the current condition, required condition, supporting photograph or drawing, responsibility, due date, verification method, and final status. If an item changes the BOM, tooling, firmware, claimed rating, packaging structure, or critical dimension, update the underlying specification and revision as well.
A useful status set is: open, corrected pending verification, verified, accepted with deviation, or rejected. Any accepted deviation should have an owner and expiry condition. This prevents a temporary concession from silently becoming the new production standard.
Why the Factory Benefits from Written Approval
A vague approval does not reduce work; it pushes risk to the end of the process, when correction is slower and more expensive. With a written target, the factory can control incoming material, tooling, assembly, laboratory verification, packaging, and final inspection against the same standard.
Two sealed samples also make later comparison faster. When both sides hold an untouched unit and the related criteria sheet, a question about colour, finish, output, accessories, or packaging can be checked against a shared baseline rather than memory. The same principle should be part of a broader adult toy factory qualification and partnership process.
Final Sample Approval Workflow Before Mass Production
Start buyer checks on the day the sample arrives, but do not promise an approval deadline until the test plan is scheduled. Run time, charging, drying and post-immersion observation, packaged drop, button-life cycling, laboratory bookings, and third-party reports can span several days or longer.
Close the sex toy sample approval checklist only after all required evidence is available and every correction has been verified, conditionally assigned, or rejected in writing.
Send the factory your model, drawing and BOM revision, target markets, claimed ratings, packaging revision, and acceptance criteria. The supplier should then identify which checks are buyer review, which are factory verification, and which require external testing. Bulk production should begin only after corrections are closed or formally assigned to an agreed first-article check.
Prepare a Sample Approval Plan for Your Next Project
Share your product revision, target market, claimed ratings, and acceptance criteria so the validation responsibilities can be defined before pre-production approval.
Frequently Asked Questions
How many sample units should I request?
Request at least three units of the same configuration for initial comparison, plus dedicated units for destructive checks. Three samples can reveal obvious inconsistency, but they do not prove process capability. Pilot and production lots still need an agreed sampling plan.
Which sample stage should provide the Golden Sample?
Use a pre-production unit whenever the schedule allows because it is made with the intended tooling, materials, line process, and packaging. An engineering sample demonstrates intent but may include hand finishing that does not represent normal output.
Can minor corrections skip re-sampling?
They can if both parties define “minor” in writing and specify how the correction will be verified. A common approach is to approve a minor correction conditionally and require a first-article photograph or inspection before the line continues.
Who pays for sample testing?
Practice varies. Agree before shipment which factory checks are included, which laboratory reports require a fee, whether sample charges credit against the first order, and which third-party tests the buyer commissions directly.
Which tests can a buyer perform without laboratory equipment?
A buyer can review appearance, colour against approved references, controls, modes, accessories, packaging, manuals, indicators, barcode function, and basic run-time under documented conditions. Instrumented, destructive, regulatory, and compliance tests should be assigned to the appropriate factory or qualified laboratory.
Does an IP rating guarantee use in a shower or bath?
No. An IP code relates to a defined ingress test on a specific configuration. The instructions, intended use, port or cap position, test report, and warranty terms still matter. Do not infer unlimited immersion or charging safety from an IP number.
What evidence should I request for a rechargeable product?
Request the exact battery and charging specification, run-time and charging records, supplier traceability, applicable safety documentation, and the UN 38.3 test summary that matches the configuration being shipped. Confirm market-specific requirements with a qualified compliance professional.
What is AQL used for after sample approval?
AQL helps define how a production lot is sampled and accepted or rejected by defect class. It does not replace the approved specification, authorize known defects, or correct a structural problem that should have been resolved during development.
How long should Golden Samples be retained?
At minimum, keep them until the order has shipped, arrived, and passed the agreed return or claim window. For repeat orders, retain them through the agreed validity period or until a new revision is approved and replaces them.
What information belongs on a signed Golden Sample?
Include the model code, drawing and BOM revision, colour, firmware or app version where relevant, packaging revision, approval date, approver names, correction-list reference, storage conditions, and validity period. Both parties should sign both sealed units.
Which changes should trigger reassessment?
Reassess changes to material grade, critical supplier, tooling, dimensions, electronics, battery, firmware, controls, charging system, claimed rating, packaging protection, labelling, or any requirement linked to safety or compliance. The depth of reassessment should match the risk of the change.
Can the same unit be used for destructive and appearance tests?
Perform appearance checks first if necessary, but do not use a dropped, immersed, opened, or life-cycled unit as the final appearance and function reference. Golden Samples must remain untouched so later production comparisons are meaningful.
