GB/T 1608-2017Potassium permanganate for industrial use (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard instead of GB/T 1608-2008 "industrial potassium permanganate", and GB/T 1608-2008 compared to the main technical differences are as follows:

--- increase the type of product, the original standard specifications for the type I, increase the quicksand products for the type II (see Chapter 4, 5.2,.2008 version of 4.2); - Added indicators to increase cadmium, chromium, mercury, mobility, moisture, and particle size (see 5.2,

4.2 of.2008); - increased test methods, increased cadmium, chromium, mercury, mobility, moisture, particle size indicators corresponding to the test method (see 6.8,6.9,6.10, 6.11, 6.12, 6.13);

--- Adjust the potassium permanganate and water insoluble indicators (see 5.2,.2008 version 4.2). This standard is proposed by the China Petroleum and Chemical Industry Association. This standard by the National Chemical Standardization Technical Committee of inorganic chemical sub-technical committee (SAC/TC63/SC1) centralized. The main drafting unit of this standard. CNOOC Tianjin Chemical Research and Design Institute, Chongqing Changyuan Chemical Group Co., Ltd., Yunnan Star Chemical has Limited company, Datong City, Beijing yuan Manganese Industry Co., Ltd., silver Chang Yuan Chemical Co., Ltd.

1 Scope

GB/T 1608-2017 is the Chinese national standard on potassium permanganate 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 12 July 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2018. 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 requirements, test methods, inspection rules and marking, labeling, packaging, transportation, storage and safety of industrial potassium permanganate. This standard applies to industrial potassium permanganate. The product is mainly used for chemical industry, metallurgical industry, environmental protection, agriculture and farming, also used For life water treatment agent, preservatives, cleaning agents and pharmaceutical industry raw materials.
