1 Scope and Purpose

This standard gives terms and definitions for electric and electronic products used in the test environment, such as. components, sub-assemblies, components and devices. Environmental conditions include. impact, vibration, climate (temperature, humidity and atmospheric pressure), the seal (against solid, liquid, gas, or immersed in maintaining pressure), Welding heat (including thermal shock generated by welding). This standard does not address fire hazard test related terms that related terms are listed in GB/T 5169 standard. We are not considered Conditions. solar radiation, mildew, corrosion, terminations strength, durability tag, dust, sand and precipitation, radiation, noise and vibration. Note 1. IEC 60068-1. 1988 Chapter 2 describes the scope of the environmental tests. Other standard environmental tests, the first chapter is about the purpose of the application And in the field. Note 2. This guide describes the test environment according to Classification of environmental conditions include terms and definitions, these environmental conditions and environmental conditions classification and grading scale Registration conditions are not the same, but also to meet the requirements of environmental test methods. Note 3. introduces some special vocabulary test environment does not have, such as those from ISO 2041 and IEC 60721-1. 1981 standard vocabulary, and gives the word Exchange relationships with other source vocabulary.
