Revised Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (Part 1) (First Revision) which is identical with ISO 16936 (Part 1) : 2020 ‘Glass in Building - Forced-Entry Security Glazing: Part 1 Test and Classification by Repetitive Ball Drop’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Glass, Glassware and Laboratoryware Sectional Committee and approval of the Chemical Division Council.

Forced entry security glazing is designed to resist impacts of a hard body, thereby delaying access of objects and/or persons to a protected space for a short period of time. This part of the standard classifies security-glazing products into categories of resistance to repetitive impacts of a steel sphere.

This standard was originally published in 2018 by adopting ISO 16936-1 : 2005. However, to keep it in line with the improved technology and then present International Standard, the first revision of this standard has been undertaken to align it with the latest version of ISO 16936-1 : 2020.
