NATIONAL FOREWORD

This Indian Standard which is identical with ISO/TS 16186 : 2012 ‘Footwear — Critical substances potentially present in footwear and footwear components — Test method to quantitatively determine dimethyl fumarate (DMFU) in footwear materials’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Footwear Sectional Committee and approval of the Chemical Division Council.

Dimethyl fumarate (DMFU) is used as a biocide preventing molds that may deteriorate leather, furniture or footwear during storage or transport in a humid climate. However, DMFU may affect consumers who are in contact with the products because it may cause painful skin contact dermatitis. The maximum limit of DMFU recommended in the leather is 0.1 mg/kg and specific test method is required to estimate DMFU with acceptable confidence level.

The text of ISO technical specification has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘Technical Specification’ appear referring to this standard, they should be read as ‘Indian Standard’

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.
