Materials and methods

Test guideline
Qualifier:
equivalent or similar to guideline
Guideline:
other: GB/T 6288-1986 Determination of particle size for granular molecular sieve
Principles of method if other than guideline:
A series of standard sieves was selected, and a given amount of samples were analyzed according to the specified conditions. According to the weight of the sieve residue at different levels, the particle size range with largest amount of screen residue was achieved, and the particle size above this was added up and calculated to the weight percent.
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
sieving
