IS 8085 : Part 28 : 2024/ISO 19958 : 2004 Methods of Test for Footwear - Part 28 Top Piece Retention Strength - Heels and Top Pieces

ICS 61.060

CHD 19

NATIONAL FOREWORD

This Indian Standard (Part 28) which is identical to ISO 19958 : 2004 'Footwear - Test methods for heels and top pieces - Top piece retention strength' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Footwear Sectional Committee and approval of the Chemical Division Council.

This Indian Standard first published as a part of IS 8085 under the general title 'Methods of test for footwear'. This part is an adoption of ISO 19958 : 2004 which specifies a test method for measuring the force required to detach the top piece from the underside of the shoe heel. The test is applicable to heels with the top piece already attached which have been removed from complete shoes, to heels alone with the top piece attached and, in some instances, to heels with separate push-in top pieces.

All heels, except reinforced slender heels with top pieces attached by steel spigots and built stacked heels, can be tested by this method.

This Indian Standard is published in several parts. The other parts in this series are:

Part 1 Dimensions, fitting, adhesion test, peel test, heat resistance test and ageing test

Part 2 Footwear performance test, stiffness test for shanks, lastometer test for cracking of uppers; and performance test for upper fabrics, coated fabrics, sock lining and other lining materials.

Part 3 Upper sole adhesion

Part 4 Resistance to crack initiation and growth - Belt flex method

Part 5 Longitudinal stiffness of shanks

Part 6 Abrasion resistance of uppers, linings and insocks

Part 7 Deformability of upper

Part 8 Delamination resistance of uppers

Part 9 Tear strength of uppers linings and insocks

Part 10 Heel attachment for whole shoe

Part 11 Attachment strength of straps, trims and accessories

Part 12 Tensile performance of elastic materials

Part 13 Seam strength for uppers, lining and insocks

Part 14 Water vapour permeability and absorption for uppers and lining

Part 15 Washability in a domestic washing machine for whole shoe

Part 16 Flexing durability for whole shoe

Part 17 Abrasion resistance for accessories shoe laces

Part 18 Peel strength before and after repeated closing for accessories touch

Part 19 Shear strength before and after repeated closing for accessories touch and close fasteners

Part 20 Flex Resistance for uppers and lining

Part 21 Strength of slide fastener pullers

Part 22 Attachment strength of end stops

Part 23 Resistance to repeated opening and closing

Part 24 Lateral Strength for slide fasteners

Part 25 Slip resistance

Part 26 Tensile strength and elongation for uppers

Part 27 Flex resistance of outsoles

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.
