IS 15727 : Part 3 : 2007 /ISO 12952-3 : 1998 Textiles - Burning Behaviour of Bending Items - Part 3 : General Test Methods for The Ignitability by a Small Open Flame

National Foreword

This Indian Standard (Part 3) which is identical with ISO 12952-3 : 1998 Textiles - Burning behaviour of bedding items - Part 3: Genaral test methods for the ignitability by a small open flame issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Chemical Methods of Test Sectional Committee and approval of the Textile Division Council,

The conditioning temperature of 20+2°C as specified in International Standard is not suitable for tropical countries like India where the atmospheric temperature is normally much higher than 20°C. It is almost impossible to maintain this temperature specially during summer when the atmospheric temperature rises even up to 50°C. In view of the above, IS 6359: 1971 Method for conditioning of textiles specifies a temperature of 27+2°C for conditioning of the test specimens for the tropical countries like India. This standard is being followed in testing of textiles and other products since decades.

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 or European Standard 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.

In reporting the results of a test or analysis made in accordance with this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS 2 : 1960 Rules for rounding off numerical values (revised).
