Classification of environmental conditions - Part 1: Environmental parameters and their severities

This document provides a classification of environmental conditions, focusing on the parameters that define the severity of environmental stresses. It outlines various environmental factors and their respective levels of severity, which are essential for the proper selection and application of materials, components, and equipment in different operational environments. The standard is structured to facilitate the identification of environmental conditions relevant to the performance and reliability of electrical and electronic products. It includes guidance on how to characterize environments based on temperature, humidity, mechanical stresses, and other relevant factors. The information presented supports the development of specifications and testing procedures that ensure the compatibility and durability of products under specified environmental conditions. This part of the standard serves as a foundational reference for subsequent parts that provide more detailed classifications and guidelines.
