GB/T 1618-2018Sodium chlorate for industrial use (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 1618-2008 "Industrial sodium chlorate", compared with GB/T 1618-2008, except for editorial modifications The changes are as follows:

--- Re-divided the type of product, increasing the requirements of wet products (see 5.2,

5.2 of.2008 edition); Potentiometric titration was added to the determination of chloride content (see 6.6,

6.7 of.2008 edition). This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Chemical Standardization Technical Committee of the Inorganic Chemical Subcommittee (SAC/TC63/SC1). This standard was drafted. Inner Mongolia Lantai Industrial Co., Ltd., Fuzhou Yihua Chemical Co., Ltd., Yatai Electrochemical Co., Ltd. Division, Sichuan Minjiang Snow Salt Chemical Co., Ltd., Zhongyan Jiangxi Lantai Chemical Co., Ltd., Qinghai Junmin Chemical Co., Ltd., CNOOC Tianjin Industrial Research and Design Institute Co., Ltd.

1 Scope

GB/T 1618-2018 is the Chinese national standard on sodium chlorate for industrial use, in the field of chemical technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 7 June 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 January 2019. Classification: ICS 71.060.50, CCS G12. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the classification, requirements, test methods, inspection rules, marking, labeling, packaging, transportation and storage of industrial sodium chlorate. This standard applies to industrial sodium chlorate. This product is mainly used in the production of chlorine dioxide, sodium chlorite and perchlorate, chlorate, and also Herbicides, oxidants, printing and dyeing, metallurgy, paper, leather.
