Përgatitja e shtresave të çelikut përpara aplikimit të bojrave dhe të produkteve të ngjashme me to - Metodat e provës për abrazivët jo metalikë që përdoren për pastrimin me shpërthim - Pjesa 2: Përcaktimi i shpërndarrjes së madhësive të kokrizave

Preparation of steel substrates before application of paints and related products - Test methods for non-metallic blast-cleaning abrasives - Part 2: Determination of particle size distribution (ISO 11127-2:1993)

Scope

The procedure includes weighing out a test portion of approximately 300 g of the sample, placing the test portion in the top sieve of a set of test sieves (including all the sieves listed against the grade under test in the appropriate part of ISO 11126) with the largest-aperture sieve on the top and progress to the smallest aperture at the bottom with a pan, to catch any abrasive that falls through the finest sieve, sieving in a sieve machine, weighing the abrasive retained on each sieve and transferred on to a balance pan. Annex A gives information on the international standards series for non-metallic blast-cleaning abrasives ISO 11126 and ISO 11127.
