А Префаце
ИСО (Међународна организација за стандардизацију) је глобални савез националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака институција чланица заинтересована за предмет за који је основан технички комитет има право да буде заступљена у комитету. У овај посао су укључене и владине и невладине међународне организације које су у вези са организацијама за стандардизацију. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

The procedures used to develop this document as well as those used for further maintenance are described in Part 1 ИСО/ИЕЦ директиве.

ИСО 8130-1-2019 Прашкасти премази – Парт 1: Determination of particle size distribution by screening

The second edition cancels and replaces the technically revised first edition (ИСО 8130-1:1992).

Compared with the previous edition, the main changes are as follows:

– Added “Terms and definitions” клаузула;

– added the “principles” клаузула;

– Increased selection of screening methods and screening selectivity;

– Increased manual screening and screening using vibration mechanism;

— The text has been edited and revised, and normative references have been updated.

A list of all parts in the ISO 8130 series can be found on the ISO website.

Any feedback or questions regarding this document should be directed to the user’s national standards body. A full list of these agencies can be found at iso.org/members.html.

1 Обим
This document specifies the method for determining the particle size distribution of paint powders by screening analysis. Particle size distributions with a maximum size of less than 100 μm were determined by laser diffraction ISO 8130-13. This method is particularly useful for determining oversized materials or the presence of contamination and can be used as a quality control procedure (” pass “/” fail “тест) by examining the amount retained on individual sieves.

The following particle sizes are typical for paint powders, but particle sizes may vary depending on the application:

– Film technology: 1 μm to 63 μм;

– Electrostatic coating: 10 μm to 200 μм;

— Fluidized bed method: 100μm and above.

Note that sifters with mesh sizes smaller than 32μm are not practical and may become blind during use.
