IS 8521 : Part 3 : 2025/ISO 16321-2 : 2021 Eye and Face Protection for Occupational Use - Part 3 Additional Requirements for Protectors Used During Welding and Related Techniques
NATIONAL FOREWORD
This Indian Standard (Part 3) which is identical to ISO 16321-2 : 2021 'Eye and face protection for occupational use: Part 2 Additional requirements for protectors used during welding and related techniques' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Occupational Safety and Health Sectional Committee and approval of the Chemical Division Council.
This document (Part 3) specifies additional material, design, performance and marking requirements for eye and face protectors designed to provide protection for the eyes and faces of persons against occupational hazards, such as optical radiation, impacts from flying particles and fragments, and hot solids during welding and related techniques. The other applicable requirements for welding protectors are given in IS 8521 (Part 1).
This Indian Standard is published in three parts. The other parts of this series are:
Part 1 General Requirements
Part 2 Additional requirements for mesh protectors
Considering the benefits of aligning standard with that of international standards, the Committee decided to prepare this standard by identical adoption of ISO 16321-2 : 2021 'Eye and face protection for occupational use - Part 2: Additional requirements for protectors used during welding and related techniques' under dual numbering.
The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions and terminologies are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker in the International Standard, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
