---GB/T 18809-2002. General specification for air ion meter

1 Scope

GB/T 18809-2019 is the Chinese national standard on general specification for air ion measuring instruments, in the field of testing. 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 30 August 2019 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 March 2020. Classification: ICS 19.040, CCS L85. 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 random documents of the air ion meter (hereinafter referred to as the instrument). This standard is applicable to the air ion measuring instrument using the working principle of "sucking capacitor collection method", which is the product development, design, production and acceptance. And the main technical basis of the inspection is also the principle and basis for the formulation of product standards and other technical documents.
