What are the customization processes of non-standard test boxes?

1. Communicate with manufacturers directly to customize requirements

 operating steps ：

Requirement submission: clear the test object (such as headlights, batteries, sensors, etc.), test scenario (such as simulated extreme cold wading, high temperature and high pressure spraying) and industry specifications (such as automobile, military, electronics);

Technology docking: provide product parameters (size, weight), environmental conditions (temperature range, impact frequency) and special requirements (such as salt spray superposition test, dynamic Angle adjustment);

Confirmation of the scheme: Based on general standards such as GB, IEC and GJB, and industry specifications such as VW 80101 and ISO 16750, the manufacturer designs customized test procedures and equipment configuration schemes.

2. Adapt to the existing standard framework

Manufacturers can expand or adjust based on the following criteria:

 national standards ：

GB/T 28046.4-2011: For the climate load test of automotive electrical equipment, the core parameters such as temperature, time and circulation times of ice water impact are defined;

GB/T 2423.1: Environmental test specification for general electrical and electronic products, supporting the design of calibration and verification process.

 codes of practice ：

VW 80101-2005: Volkswagen Electric Components Test Standard, applicable to the refinement of parameters such as spray pressure and water temperature accuracy;

GMW3172: General Motors global engineering standard, supporting multi-environment composite testing (such as ice water impact + salt spray corrosion);

ISO 16750-4:2006: International common vehicle electrical equipment test framework, compatible with customized cycles (e.g. 100 standard or 200 enhanced).

Third, optimize standards by using manufacturers' technical resources

Flexible parameter adjustment:

Temperature range: standard high temperature range 65~160℃, can be extended to-70℃ to +150℃;

Water splashing system: support flow (3~4L/3S or 80L/min), distance (325±25mm adjustable), nozzle type (gap/matrix) and other customization;

Intelligent control: the PLC system can customize the temperature switching rate (such as 20 seconds to complete the conversion from extreme cold to high temperature), data acquisition frequency and report format.

Function module superposition:

Compatible with multiple test requirements such as waterproof (IPX5-6) and dustproof (IP5X-6X);

Support dynamic Angle spraying (15 ~75 adjustable), salt spray composite test and other complex scene simulation.

4. Ensure compliance through certification and verification

Equipment calibration: the manufacturer provides half-year temperature sensor calibration service, the error is controlled within ±2℃;

Third-party verification: it is recommended to certify the temperature change rate, uniformity and other indicators of customized equipment through quality inspection institutions (such as China Electric Power Research Institute, FAW test site);

Data traceability: The test chamber supports USB export of test logs, which is convenient for quality traceability and standard iteration.

5. Service support and case reference

Technical team: Guangdong Hongzhan cooperates with universities and research institutes to provide whole-process support from demand analysis to standard implementation;

Case library invocation: You can refer to the car company case (such as 800V battery pack IPX9K test, intelligent lamp cold and hot cycle verification) to optimize and customize the standard;

After-sales guarantee: customized equipment enjoys 1 year warranty and 48 hours door-to-door maintenance to ensure the stability of standard implementation.
