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.

ИСО 7590-2018 “Wire rope conveyance belts – Determination methods for total thickness and cladding thickness”

1 Обим
This document specifies three methods for measuring the total thickness and cover thickness of steel cord conveyor belts.

Methods A1 and A2 (micrometer method) can be used for all steel cord conveyor belts to measure total belt thickness and overlay thickness.

Метода Б (optical method) is only used to measure cover thickness. If there is textile or metal weft, it is also not suitable for the end of the wire rope to twist when cutting.

3.1 Circuit breaker
The lateral reinforcement material in the conveyor belt, usually made of textile material, is inserted above and below or above or below the wire rope at a distance of at least 1 mm and is considered as part of the lid

Белешка 1: It is used to protect longitudinal ropes from material damage caused by impact or jam.

3.2 Fabric
The transverse parts of the protective reinforcement of the steel cord or textile cord, usually inserted above and below the steel cord, or above or below, at a distance of less than 1 мм, are considered to be part of the conveyor belt body
