This part replaces GB/T 4798.1-2005 "Electrical and Electronic Products Application Environmental Conditions Part 1. Storage". This part and

Compared with GB/T 4798.1-2005, the main technical changes are as follows.

--- The standard name was changed to "Environmental Condition Classification Environmental Parameter Group Classification and Its Severity Classification Part 1. Storage";

--- Added Chapter 3 "Terms and Definitions", and the subsequent chapter number changes accordingly;

--- Added a description of "impacts on short-term extreme environmental conditions" and "long-term effects on non-extreme environmental stresses" (see Chapter 4);

--- "Climatic environmental conditions" "Mechanical active material conditions" "Mechanical environmental conditions", replacing the old classification with a new classification (see 5.2,

1 Scope

This part of GB/T 4798 applies to the environmental parameters of the stored product and the grading of its severity. The product can be stored with
