Environmental requirements for pretreatment of anti-static auxiliary material sample certification test
According to the requirements of the American ESDA ANSI/ESD S20.20 standard, when the factory purchases anti-static accessories, it must do the certification before the product is delivered, so what are the environmental requirements when doing the sample certification? Now we come to reveal the answer to this question:
Low humidity environment: 12±3%RH, temperature 23±3℃, sample pretreatment time is at least 48 hours;
Medium humidity environment: 50±5%RH, temperature 23±3℃, sample pretreatment time is at least 48 hours.
Note: The pretreatment time of the sample varies depending on the article. For example, the floor requirement is 72 hours, and the work clothes requirement is 48 hours. The specific sample pretreatment time can refer to various article standards issued by ESDA. definition.
