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 (види исо.орг/дирецтивес).

3.1 Blasting force FD

The test piece of tissue paper or tissue paper product is applied perpendicular to its surface with the greatest force that it can withstand under test conditions

[Извор: ИСО 12625-9:2015, 3.2, modified – Right Angle changed to vertical]

Белешка 1: The blasting force is expressed in Newtons (Н).

3.2 Wet blasting force

Maximum force, the maximum force that a tissue paper or tissue paper product wetting test piece can withstand under test conditions, applied perpendicular to its surface

Белешка 1: Wet blasting force is expressed in millinewtons (мН).

ИСО 12625-11-2019 “Тоалетни папир и производи од санитарног папира – Парт 11: Determination of wet bulb bursting strength”

3.3 Wet explosion index

The wet bursting force of tissue paper or tissue products divided by the gram weight of the regulated sample determined by the standard test method

Белешка 1: The wet explosion index is expressed in millinewtons square meters per gram (mN · m2 /g).

3.4 Wet blasting retention

The ratio of the bursting strength of a wet paper towel or wet paper towel product to the bursting strength of the same tissue paper or paper towel product under dry and conditioned conditions, expressed as a percentage

Белешка 1: This definition is similar to the definition of wet tensile strength retention; See ISO 12625-5:2016, 3.2.
