IS 1367 : Part 11 : 2024/ISO 4042 : 2022 Technical Supply Conditions for Threaded Steel Fasteners - Part 11 Electroplated Coating Systems

ICS 21.060.01

PGD 37

NATIONAL FOREWORD

This Indian Standard (Part 11) (Fifth Revision) which is identical to ISO 4042 : 2022 'Fasteners - Electroplated coating systems' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the General Engineering and Fasteners Standards Sectional Committee and after approval of the Production and General Engineering Division Council.

This standard was first published in 1961 and was subsequently revised in 1967, 1996, 2002 and 2020. This fifth revision has been brought out to align it with the latest version of ISO 4042.

The major changes in this revision are as follows:

a) In clause 1, a statement has been added that the requirements of this standard for electroplated fasteners have precedence over other standards dealing with electroplating;

b) In clause 4.4, the measures to prevent internal hydrogen embrittlement for nuts, flat washers and case-hardened screws have been completely revised; and

c) In clause 6.4, the reference areas for thickness determination have been more clearly specified.

This standard is published in 18 parts. Other parts in this series are:

Part 1 General requirements for bolts, screws, studs and nuts

Part 2 Tolerances for fasteners - Bolts, screws, studs and nuts - Product grades A, B and C

Part 3 Mechanical properties of fasteners made of carbon steel and bolts screws and studs

Part 5 Mechanical properties of fasteners made of carbon steel and alloy steel - Set screws and similar threaded fasteners with specified hardness classes - Coarse thread and fine pitch thread

Part 6 Mechanical properties of fasteners made of carbon steel and alloy steel - Nuts with specified property classes - Coarse thread and fine pitch thread

Part 7 Mechanical properties and test methods for nuts without specified proof loads

Part 8 Prevailing torque type steel nuts - Functional properties

Part 9 Surface discontinuities

Part 10 Surface discontinuities - Nuts

Part 12 Phosphate coatings on threaded fasteners

Part 13 Hot dip galvanized coatings on threaded fasteners

Part 14 Mechanical properties of corrosion-resistant stainless-steel fasteners

Part 16 Designation system for fasteners

Part 17 Inspections, sampling and acceptance procedure

Part 18 Packaging

Part 19 Axial load fatigue testing of bolts, screws and studs

Part 20 Torsional test and minimum torques for bolts and screws with nominal diameters 1 mm to 10 mm

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.
