IS 16915 : Part 2 : 2024/ISO 16181-2 : 2021 Footwear - Critical Substances Potentially Present in Footwear and Footwear Components - Part 2 Determination of Phthalates Without Solvent Extraction
NATIONAL FOREWORD
This Indian Standard (Part 2) (First Revision) which is identical to ISO 16181-2 : 2021 'Footwear - Critical substances potentially present in footwear and footwear components - Part 2: Determination of phthalate without solvent extraction' 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.
Phthalates are commonly used as plasticizers in polymers. Phthalates are controversial because high doses of many phthalates have shown hormonal activity in rodent studies. Studies on rodents involving large amounts of phthalates have shown damage to the liver, the kidneys, the lungs, and the developing testes. Hence, its use is prohibited in footwear and this standard prescribes a test method for determining the presence of phthalate compounds in footwear materials.
This standard was first published in 2018 as an identical adoption of ISO 16181 : 2011 under dual numbering.ISO 16181 : 2011 was bifurcated into two parts that is ISO 16181 (Part 1) Determination of Phthalates with solvent extraction' and ISO 16181 (Part 2) 'Determination of Phthalates without solvent extraction'. Hence, the Committee decided to undertake the revision of IS 16915 by adopting ISO 16181 (Part 1) as IS 16915 (Part 1)/ISO 16181 (Part1) and ISO 16181 (Part 2) as IS 16915 (Part 2)/ ISO 16181(Part 2).
This part specifies a method for the determination of the content of specific phthalates (see Annex A) by pyrolyzer/thermal desorption gas chromatography-mass spectrometry (Py/TD-GC-MS). This document is applicable to all types of footwear materials except textiles.
In this revision following modifications have been done:
a) phthalates were added to the list in Table A.1 (from 7 onwards); and
b) This document introduces a new technique.
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.
