ISO 36-2020 pdf free.Rubber, vulcanized or thermoplastic — Determination ofadhesion to textile fabrics.
This document specifies a method of test for measuring the force required to separate, by stripping,two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together.
The method is applicable when the ply surfaces are approximately plane or when they are in theform of a cylinder having an internal diameter greater than approximately 50 mm.The method is notapplicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannotbe excluded when cutting out test pieces.This document does not apply to coated fabrics, which are tested in accordance with IS0 2411,or textileconveyor belts, which are tested in accordance with ISO 252.
The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.For dated references,only the edition cited applies. Forundated references, the latest edition of the referenced document (including any amendments) applies.
The stripping force required to separate two plies of fabric bonded with rubber, or a rubber layer anda fabric ply bonded together, is measured under specified conditions using test pieces of standarddimensions in the form of a flat strip.
Test machine, power-driven and equipped with a suitable dynamometer; it shall be capable ofmaintaininga substantially constant rate of traverse of the moving head during the test and shall be linkedto an autographic recorder or a computer with graphic capabilities for data acquisition and processing.Adynamometer without inertia(e.g. of the electronic or optical type) should preferably be used.
The machine shall comply with the requirements of IlSO 5893, be capable of measuring force with anaccuracy corresponding to class 1 as defined in IS0 5893:2019, and have a rate of traverse of the movinggrip of 50 mm/min 5 mm/min.
The machine shall be fitted with grips capable of holding the test piece and the ply to be separatedwithout slipping during the test.
Autographic recorder, with a scale sufficiently large to permit easy interpretation of the trace, orcomputer with graphic capabilities and software enabling it to be in accordance with the procedure fordata processing described in ISo 6133.ISO 36 pdf download.
