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. Нарочито, треба обратити пажњу на различите критеријуме одобрења који су потребни за различите типове ИСО докумената. This document has been drafted in accordance with the editing rules of ISO/IEC Directive Part 2 (see.iso.org/directives).

The committee responsible for this document is ISO/TC 6, Папир, Board and Pulp, Пододбор СЦ 2, Test Methods and Quality Specifications for Paper and Paperboard, in accordance with the Technical Cooperation Agreement between ISO and CEN (Vienna Agreement), by the Technical Committee of the European Committee for Standardization (CEN) CEN/TC 172, Pulp, Paper and Paperboard.

The second edition cancels and replaces the first edition of ISO 12625-9:2005, which has been technically revised.

The following changes were made:

– Reformulation of article 4;

– The inner diameter of the two concentric rings is reduced to 50 мм;

– Simplified description of the procedure in Article 9;

– Added accurate data in Annex A;

– Edit updates.

увести
Овај део ИСО-а 12625 applies to tissue and household paper products. In principle, it can be applied to other paper types, but this part of ISO 12625 is not included.

It is clearly stated that the testing of impurities and impurities in tissue and tissue products is carried out in accordance with ISO 15755.

To determine moisture content in tissue and tissue products, ИСО 287 и ИСО 638 are applied.

ИСО 12625-9-2015 “Toilet paper and sanitary paper products – Парт 9: Determination of the bursting strength of the ball”

1 Range
Овај део ИСО-а 12625 specifies a test method for determining the mechanical permeability (ball burst strength procedure) of tissue and household paper products.

Сада, there are two different diameter clamping devices on the market, one is 50 mm and the other is 89 мм (see Annex B). Овај део ИСО-а 12625 applies to 50 mm clamping devices and is capable of measuring all sample sizes of tissue paper and tissue paper products and is consistent with ISO 12625-11.
