APPIE prepare and distribute the test powders named SAP test powder 3 which are based on SAP 14-12 : 2012 (APPIE Standerd).
SAP test powders 3 includes four test powders which have smaller size distribution compared to the JIS Z 8901 Test powders 1, and they can be used for the performance test of various dust collectors and air filters as well as for durability test of various instruments when they are exposed to dust particles.
SAP test powders 3 are classified into four classes, their used material are quarts sand, talc, sintered KANTO loam, and calcium carbonate heavy and their chemical compositions are same to the used material of JIS Z 8901 Test powders 1.
