company news about Temperature Humidity Test Chamber Test Standards ！

1. International Universal Core Standards

• IEC 60068 Series (International Electrotechnical Commission): Focuses on environmental testing of electrical and electronic products.
  1. IEC 60068-2-3: Steady-state damp heat test. Specifies fixed conditions (e.g., 40℃/93%RH) to evaluate product resistance to moisture and heat aging.
  2. IEC 60068-2-78: Damp heat, cyclic test. Combines temperature cycles (e.g., -20℃~60℃) with humidity changes to simulate alternating environmental impacts.
• ISO 16232 Series (International Organization for Standardization): Dedicated to environmental testing of automotive components.
  • Covers tests for parts like electronic modules and interior trim, with conditions such as high temperature/humidity (85℃/85%RH) and low temperature/low humidity (-40℃/≤10%RH) to match real-world automotive usage.

3. Industry-Specific Standards

• Semiconductor Industry: JEDEC JESD22-A101 (U.S. Joint Electron Device Engineering Council). Includes High Temperature High Humidity Bias (HTHHB) tests (85℃/85%RH with rated voltage) to assess electrochemical migration risks in semiconductors.
• Automotive Industry: SAE J2380 (Society of Automotive Engineers). Requires tests for automotive electronics in a temperature range of -40℃~125℃ with varying humidity to ensure performance under extreme driving conditions.
• Military Industry: GJB 150.9A-2009 (China National Military Standard). Specifies long-duration damp heat tests (up to 60 days at 30℃~60℃/85%~95%RH) for military equipment to meet high durability requirements.
