Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is modified to adopt ISO 23464:2020 "Specification for nitrile gloves for cleanroom use".

This document has the following structural adjustments compared to ISO 23464:2020.

--- Added Appendix A and Appendix B.

The technical differences between this document and ISO 23464:2020 and their reasons are as follows.

--- Changed the scope of the statement (see Chapter 1) to conform to my country's national conditions;

--- Added normative reference to ISO 14644-1 (see A.2.2, A.2.5.3.3.1) to comply with the test for liquid agitation particle generation test Test conditions;

--- Deleted the normative reference IEST-RP-CC005.4.2013 (see Chapter 5 and Chapter 7 of ISO 23464:2020) and replaced Chapter 16 and Chapter 17 of IEST-RP-CC005.4.2013 are included as Appendix A, Appendix A of IEST-RP-CC005.4.2013 as Appendix B, it conforms to my country's national conditions and facilitates the use of the standard.

The following editorial changes have been made to this document.

--- In order to coordinate with the existing standard system, the standard name is changed to "Nitrile gloves for clean room use".

3 Terms and Definitions

The following terms and definitions apply to this document.

clean room

A dedicated room with floors and walls free of particle adsorption and release.

Note. The circulating air needs to be filtered through a high efficiency air filter (HEPA) or an ultra low particle air filter (ULPA). The main purpose is to minimize the impact on the work Contamination of the workbench, products being produced, and operators.

laminar airflow

uniform airflow (as opposed to turbulent airflow) within a cleanroom (3.1) that ensures that all detached particles (3.5) are effectively removed from the cleanroom 3.3 RO-DI treated water Water with very low particle (3.5) and ion content.

resistivity

The resistance of a particular material (rubber) to the flow of electric current.

Note. The unit of resistivity is Mohm, which is an indicator for measuring the purity of RO-DI treated water (3.3). The optimal purity is 18 Mohm.

particles

Solid, liquid, or both substances with a size usually between 1nm and 1mm.
