Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 8770-1988 "molecular sieve dynamic water adsorption measurement method", compared with the GB/T 8770-1988 Technical
Changes are as follows.
--- Cancel the size requirements of the sample, the measurement conditions close to the conditions conditions of use;
--- Changing the feed gas adsorption temperature and humidity, a simple measurement method.
The standard proposed by China Petroleum and Chemical Industry Association.
This standard by the National Standardization Technical Committee fertilizer and soil conditioner molecular sieve Technical Committee (SAC/TC105/SC6)
Centralized.
