The GB/T 10739-2002 standard specifies the standard atmospheric conditions required for Sample Handling and Testing of Paper, Cardboard and Pulp. This standard is an amendment to GB/T 10739-1989 and is equivalent to ISO 187:1990. The standard requires laboratories to perform Sample Handling and testing in an environment at a temperature of 23 +/- 1 ° C and a relative humidity of 50% +/- 2%. The standard details the sample pretreatment and temperature and humidity treatment steps, and specifies the determination method and technical requirements for laboratory atmospheric conditions, including laboratory temperature, Humidity accuracy and air circulation. These conditions ensure the accuracy and conformity of the test results.
