Introduction

Environmental exposure to typical products typically include a number of environmental conditions, GB/T 4798 provisions of these conditions were divided into climate , Mechanical, biological and other chemical effects due to the active substance and the bioactive substance-induced. GB/T 20159 considers only the gas Weather conditions and mechanical conditions.

In this section, references to the following series of criteria.
