Chemical Hazards Sectional Committee, CHD 7 FOREWORD This Indian Standard ( Second Revision ) was adopted by the Bureau of Indian Standards, afier the draft final ized by the Chemical Hazards Sectional Committee had been approved by the Chemical Division Council. The handling of dangerous goods during transportation is regulated in order to prevent such goods from causing either accidents to persons or damage to the means of transport employed or to other goods. Keeping these objectives in view, this standard lists dangerous substances and classifies them according to risk involved so that appropriate precautions can be taken by the concerned agencies. This standard was first published in 1959 based on the recommendations prepared by the United Nations Committee of Experts on the Transport of Dangerous Goods, namely, Document ST/ECA/43/E/CN2/l 70 October 1956. First revision of this standard was published in 1985 incorporating the then latest recommendations of this UN Committee. Recently the UN have published tenth revised edition as ST/SG/AC 10/1/Rev. This revised standard incorporates the latest information from this UN document. There is no 1S0 standard on this subject. Since there is no Indian Standard for determination of flammability of gases and gas mixtures in air, 1S0 10156: 1996 ‘Gases and gas mixtures — Determination of fire potential and oxidizing ability for the seIection of cylinder valve outlets’ has been referred in Table 1, main risk classification No.2. 1and Annex A of this standard. This standard will be taken up for adoption as Indian Standard in due course of time. WhiIe preparing this standard, it is recognized that the type of packing can have a decisive effect upon the hazard during transport. However, this aspect has not been covered in this standard and for the purpose reference should be made to the UN documents referred to in para. The composition of the Committee responsible for formulation of this standard is given in Annex B, For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2: 1960 ‘Rules for rounding off numerical values ( revised )’. The number of significant places retained in the rounded off value should b e the same as that of the specified value in this standard. .
