Global Compliance & Testing Lab
YueFong operates internal hardware testing and quality verification processes for mechanical security products, including corrosion testing, tensile testing, shackle cutting evaluation and production-batch checks.Recorded QA data provides buyers with measurable evidence beyond product appearance alone.
For international B2B buyers, compliance and repeatable performance are part of the procurement process.YueFong combines production quality control with internal laboratory verification so measurable test results can be linked directly to product development and manufacturing.Where customer projects require third-party or market-specific certification, the applicable test pathway can be defined during technical development.
Mechanical & Corrosion Testing
Recent quality-assurance tests on 50 mm combination padlock samples included salt-spray exposure, destructive tensile loading and shackle cutting evaluation.
Anti-Corrosion Endurance
- Method: Neutral Salt Spray test conditions, 35°C ± 2°C and 5% ± 1% NaCl.
- Recorded duration: 240 continuous hours .
- Photographic records were captured at multiple exposure intervals for visual comparison.
- Relevant for outdoor, coastal and corrosion-sensitive hardware applications.
Destructive Tensile Strength
- Test scope: destructive tensile loading of 50 mm combination padlock samples.
- Recorded QA values: 2,708 N / 2,642 N .
- Results are evaluated against the applicable internal or customer-defined test criteria.
- Relevant for logistics, warehouse and industrial security applications.
Shackle Cutting Resistance
- Test scope: hydraulic cutting load applied to the shackle.
- Recorded QA values: 17,974 N / 18,538 N .
- Test values depend on the selected shackle material and product configuration.
- Applicable to higher-security mechanical lock configurations.

Mechanical Hardware Meets Digital Access
Smart-lock validation extends beyond mechanical hardware. Electronics, connectivity and biometric modules can be evaluated according to the selected product architecture and customer project requirements.
Ecosystem & App Integration
Product development can include integration testing for platforms and connectivity frameworks such as Tuya, TTLock, Bluetooth Low Energy and Wi-Fi, depending on the selected solution.
Biometric Component Validation
Smart-lock projects may include fingerprint, facial-recognition and related biometric modules. Sensor calibration and recognition performance are evaluated according to the final hardware and firmware configuration.
Certification Built Into Development
International buyers often require different compliance pathways depending on target country, application and product category.YueFong can align product development with applicable quality, safety, environmental and market-entry requirements during the technical planning stage.Where third-party testing or certification is required, the relevant scope can be confirmed before tooling and mass production.
Testing & Compliance FAQ
Is hardware testing performed in-house?
YueFong uses internal quality-control and hardware-testing processes for corrosion, mechanical load and production verification. Specific customer projects may also require independent third-party testing.
What test documentation can buyers review?
Available documentation can include internal laboratory records, product-specific test reports and customer-required third-party reports, depending on the order and certification scope.
Can buyers audit the factory and test process?
Factory visits, technical discussions and quality-verification reviews can be arranged during B2B project development.
Can higher salt-spray requirements be specified?
Yes. Salt-spray requirements can be defined according to the intended environment, selected material, surface treatment and customer specification.The test data shown on this page includes a 240-hour exposure record for a 50 mm combination padlock sample.
Does YueFong also validate smart-lock hardware?
Smart-lock projects can include connectivity, biometric and application-integration validation in addition to mechanical and environmental testing, depending on the product configuration.
