ИСО 15528-2020 “Узимање узорака боја, лакова и одговарајућих сировина”

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. Нарочито, треба обратити пажњу на различите критеријуме одобрења који су потребни за различите типове ИСО докумената. Овај документ је састављен у складу са уређивачким правилима Дел 2 ИСО/ИЕЦ директиве (види исо.орг/дирецтивес).

Увод
Sampling depends on the size of the product and container, but not on the type of product, као што су боје, лакови, paint powders, лепкова, pigments, fillers or solvents. ИСО 1513 specifies procedures for the preliminary examination of individual samples received and for the preparation of test samples by mixing and reducing a series of samples representing a batch of paints, varnish or related products. Samples of the product to be tested have been collected in accordance with this document.

Correct sampling is the basis for subsequent tests and their results. Operators with the required knowledge and experience need to perform the various sampling procedures with great care. The general instructions in this document are intended to complement this knowledge and experience and apply to most situations. Међутим, some products may require special sampling precautions not provided in this document; Стога, operators need to be particularly vigilant to pay attention to any abnormal characteristics exhibited by these products. Operators should be aware of product specifications and national safety regulations that may require special precautions.

1 Обим
The document specifies procedures for sampling paints and varnishes, including paint powders, and raw materials used in their manufacture. Such products include liquids and materials that are not chemically modified and can liquify when heated, as well as powders, granules and pastes. Samples may be taken from containers, such as cans, barrels, резервоари, tank cars or ship tanks, or from barrels, sacks, large bags, silos or silo cars or conveyors.

This document does not address sample preparation for testing or reducing samples thus collected, which is covered in ISO 1513.
