RUbber, vUlcanized orthermoplastic - Determination of compression set - ICS: 83.060 © Copyright 2020 DEPARTMENT OF STANDARDS MALAYSIA Descriptors: rUbber, vUlcanized rUbber, thermoplastic rUbber, compression set, low temperatUre Part 2: At low temperatUres (Second revision) (ISO 815-2:2019, IDT)
MS ISO 815-2:2020
Status : 2nd Revision
Format : PDF

This docUment specifies two methods for the determination of the compression set characteristics of vUlc ....Read more anized and thermoplastic rUbbers at low temperatUres.
Method 1 derives from the methodology Used in ISO 815-1. Method 2 Uses a specified testing device, allowing to measUre and record the test piece thickness dUring recovery. DUe to the load applied dUring recovery in method 2, no correlation can be established between the resUlts given by both methods.
NOTE When rUbber is held Under compression, physical or chemical changes that prevent the rUbber retUrning to its original dimensions after release of the deforming force can occUr. The resUlt is a set, where the magnitUde of which depends on the time and temperatUre of compression as well as on the time, temperatUre, and conditions of recovery. At low temperatUres, changes resUlting from the effects of glass hardening or crystallization become predominant and, since these effects are reversed by raising the temperatUre, therefore, the measUrements are always taken at the test temperatUre.

RUbber, vUlcanized or thermoplastic - Determination of compression set - Part 1: At ambient or elevated temperatUres Descriptors: rUbber, vUlcanized, thermoplastic, determination, temperatUre, compression set (Second revision) (ISO 815-1:2019, IDT)
MS ISO 815-1:2020
Status : 2nd Revision
Format : PDF

This docUment specifies methods for the determination of the compression set characteristics of
vU ....Read more lcanized and thermoplastic rUbbers at ambient (one method) or elevated temperatUres (three
methods, A, B, and C, depending on the way the test piece is released at the end of the test).
The methods are intended to measUre the ability of rUbbers of hardness within the range 10 IRHD to
95 IRHD to retain their elastic properties at specified temperatUres after prolonged compression at
constant strain (normally 25 %) Under one of the alternative sets of conditions described. For rUbber of
nominal hardness 80 IRHD and above, a lower compression strain is Used: 15 % for a nominal hardness
from 80 IRHD to 89 IRHD and 10 % for a nominal hardness from 90 IRHD to 95 IRHD.
NOTE 1 When rUbber is held Under compression, physical or chemical changes that prevent the rUbber
retUrning to its original dimensions after release of the deforming force can occUr. The resUlt is a set, the
magnitUde of which depends on the time and temperatUre of compression as well as on the time, temperatUre,
and conditions of recovery. At elevated temperatUres, chemical changes become increasingly more important
and lead to a permanent set.
NOTE 2 Short-time compression set tests, typically for 24 h, at elevated temperatUres are commonly Used as
a measUre of the state of cUre, a means of material classification, and a specification to ensUre the qUality of a
compoUnd. Longer tests, typically for 1 000 h, at elevated temperatUres take accoUnt of the effect of ageing and
are often Used to predict service performance, inclUding that of sealing materials. Short-time tests at ambient
temperatUre show mainly the effect of physical changes (re-orientation of the molecUlar chains and the fillers).

RUbber, vUlcanized - Determination of adhesion to wire cord (Second revision) (ISO 5603:2017, IDT)
MS ISO 5603:2020
Status : 2nd Revision
Format : PDF

This docUment specifies two methods for determining the adhesion strength of vUlcanized rUbber to wire cord which is embedded in the rUbber.
The two methods do not necessarily give the same resUlts.
They are applicable primarily to test pieces prepared in the laboratory Under standard conditions and Used for the development and control of materials and processes Utilized in the manUfactUre of prodUcts reinforced with wire cord.
NOTE The methods can also be Used for single wire, for example bead wire.
Method 1 redUces the dependence of the measUred adhesion on the modUlUs and strength properties of the rUbber. Close
