IS 9405 : 2024/ISO 1120 : 2012 Conveyor Belts - Determination of Strength of Mechanical Fastenings - Static Test Method
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical to ISO 1120 : 2012 'Conveyor belts - Determination of strength of mechanical fastenings - Static test method' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Conveyor Belts Sectional Committee and approval of the Production and General Engineering Division Council.
The determination of the strength of mechanical fastenings is essential in various engineering and construction applications to ensure the safety and reliability of the joined components. Mechanical fastenings include various types of fasteners like bolts, screws, nuts, rivets, and welds.
Mechanical fastening is the most common method of joining many materials within industry. Originally used for metal joining, it is also well established for joining plastics to themselves and to other materials. There are two main categories of industrial fasteners, permanent and non-permanent:
a) Permanent Fasteners, such as rivets and nails, are single-use fasteners that are designed to permanently join two materials or parts. Removing the fastener destroys it; and
b) Non-permanent fasteners, on the other hand are designed to allow for easy removal and reuse. This standard was first published in 1980. The first revision has been undertaken to align it with ISO 1120 : 2012.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions 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 while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
