1 Scope

GB/T 1653-2023 is the Chinese national standard on o-, p-chloronitrobenzene, 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 6 August 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2024. Classification: ICS 71.100.01, CCS G56. 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 document specifies the requirements, safety information, sampling, test methods, inspection rules, signs and labels for o-nitrochlorobenzene and p-nitrochlorobenzene. Signing, packaging, transportation and storage. This document applies to product quality control of o-nitrochlorobenzene and p-nitrochlorobenzene. Molecular formula.C6H4ClNO
