Basic environmental testing procedures. Part 2 : Tests. Test B: Dry heat.

This technical specification outlines a fundamental procedure for evaluating the resistance of electrical and electronic equipment under conditions of elevated temperature without humidity. It serves as a specific supplement to the primary test methods dedicated to dry heat exposure. The document details the operational parameters required to subject specimens to controlled thermal environments, ensuring that performance and safety criteria are assessed accurately. It defines the necessary equipment characteristics, test chamber configurations, and the progression of temperature exposure over time. This approach allows manufacturers and testing laboratories to simulate harsh climatic conditions that devices might encounter during transport, storage, or operation in hot climates. By adhering to these prescribed protocols, stakeholders can verify that products maintain their functional integrity when exposed to sustained high heat. The method provides a standardized framework to facilitate consistent data collection and comparison across different industries and regions, supporting quality assurance processes without deviating into performance evaluation.
