E-ABRASIC P 12 to P 220 for coated abrasives products

Grain size distributions The testing of E-ABRASIC P 12 to P 220 grits according to FEPA-Standard 43-1:2006 resp. ISO 6344 is carried out by comparative sieving of mastergrit and sample on common use utility test sieves. The test shall be carried out with test sieving machines giving reproducible and comparable results e. g. RO-TAP-test sieving machines according to FEPA-Standard 43-1:2006 resp. ISO 9284. The mastergrits represent the reference for the grain size testing for coated abrasives products. Each supply of mastergrits shall be accompanied by a test certificate of the Staatlichen Materialprüfungsanstalt Darmstadt (MPA Darmstadt) indicating the sieving analysis and the respective date of test of the mastergrits. The result shall be related to the certified values of the mastergrits of MPA Darmstadt and hence to the corrected sieve analysis of the sample. Tabelle 1.

2/2 E-ABRASIC P 12 to P 220 for coated abrasive products

The sample is in accordance with the standard when the corrected sieve analysis of the sample is within the permissible limits given in table 1. If the values of the corrected sieve analysis are not within the permissible limits a second sample shall be taken and a new sieving carried out. Example: Test sieving of the grain P 80. The corrected sieving analysis of the sample indicates that the permissible limit of the grain P 80 is in accordance with the standard for coated abrasives grains according to table 1.
