Introduction: Huiyin Audio improved its product testing system on February 24, 2025, and equipped professional quality inspectors to conduct product testing before shipment. The specific inspection items are as follows:
February 24, 2025
I. Aging test
Standard:
·High temperature aging reference IEC 60068-2-1, wet heat aging reference IEC 60068-2-30;
·Test parameters are set according to device type and usage scenario (such as input voltage, temperature and humidity range)
Purpose:
·Verify long-term performance stability and predict product life attenuation law;
·Expose potential defects (such as circuit short circuit, material deformation) and optimize design
II. Drop test
Standard:
·IEC 60068-2-31 (free drop test), the drop height is graded according to the product weight (such as 30.48cm~76.2cm)
Purpose:
·Simulate transportation or accidental drop scenarios to detect shell structural damage and internal component loosening risks;
·Ensure the functional integrity of the product under extreme impact
III. High and low temperature test
Standard:
·Operating temperature range -30°C~+80°C, storage temperature -40°C~+85°C (refer to IEC 60068 series)
Purpose:
·Evaluate the tolerance of materials under extreme temperatures (such as plastic embrittlement, electronic component failure);
·Verify the performance stability during sudden temperature changes (such as the impact of condensation on circuits)
IV. Salt spray test
Standard:
·Neutral salt spray (NSS), acetic acid salt spray (AASS), etc., the corrosion level is determined by area or time
Purpose:
·Detect the corrosion resistance of metal parts and surface coatings;
·Prevent oxidation or functional failure caused by humid and salty environments
V. Tensile test & Cable fatigue test
Standard:
·Interface plug-in test refers to IEC 60512, cable bending test follows industry specifications
Purpose:
·Ensure the mechanical strength of the interface (e.g. no damage after 5000 plug-ins);
·Verify the conductive properties of the cable after repeated bending (e.g. resistance change ≤10%)
Summary:
Strict control of product quality and pursuit of high quality standards are Huiyin Audio's commitment to customers!
