Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with ISO 16321-1 : 2021 ‘Eye and face protection for occupational use - Part 1: General requirements’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Occupational Safety and Health Sectional Committee and approval of the Chemical Division Council.

IS 8521 (part 1) was originally published in 1971 under the title ‘Specification for industrial safety saceshields: Part 1 With plastics visor’. This specification covered the face shields (with plastics visor) that could be used in woodworking operations against chips and sawdust; in metal machining operations against flying particles; in buffing, polishing and grinding operations where particles may strike the face; in spot welding; and in the handling of corrosive materials. The standard is being revised in order to align it with the latest version of ISO 16321-1 : 2021.

This revision is also superseding IS 5983 : 1980 ‘Specification for eye-protectors’ which covered the specification for eye-protectors that could be used in operations where small particles flying at high velocity, molten metal, chemical splashes, dust, gases, optical radiations (ultra-violet, infra-red and glare from intense visible light) pose hazards which are likely to impair vision or damage the eye.
