увод
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 тој комисији. Међународне владине и невладине организације које су у вези са ИСО такође су укључене у овај посао. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електричне стандардизације.

Процедуре које се користе за израду овог документа и оне које се користе за даље одржавање описане су у Делу 1 ИСО/ИЕЦ директиве.

ИСО 8504-1-2019 “Preparation of steel substrates before use in paints and related products – Методе површинске обраде – Парт 1: General principles”

увести
The protective coating properties of paint and related products applied to steel are significantly affected by the surface state of the steel before coating. Главни фактори за које се зна да утичу на овај учинак су

– The presence of rust and dirt,

– The presence of surface contaminants, укључујући и со, прашина, уље и маст, и

– Surface outline.

ИСО 8501 серије, ИСО 8502 series and ISO 8503 series provide methods for assessing these factors, док ИСО 8504 series provides guidance on preparation methods that can be used to clean steel substrates, indicating the ability of each to achieve specified levels of cleanliness.

These international standards do not contain recommendations for protective coating systems applied to steel surfaces. They do not contain recommendations for surface quality requirements for specific situations, even though surface quality has a direct impact on the choice of protective coatings and their performance. These recommendations are found in other documents such as national standards and codes of practice. These international standards are used to ensure specified quality

ИСО 8504-1-2019 “Preparation of steel substrates before use in paints and related products – Методе површинске обраде – Парт 1: General principles”

– Compatible with and suitable for the environmental conditions to which the steel will be exposed and the protective coating system to be used, и

– Within the capacity of the specified cleaning procedure.

This document should be read in conjunction with ISO 8504-2, ИСО 8504-3, which describe specific surface treatment methods.

1 Домет
This document describes the general principles for selecting a method for preparing steel surfaces prior to the application of paints and related products. It also contains information about the characteristics to be considered when selecting and specifying certain surface treatment methods and preparation grades.
