Rubber and rubber products — Determination of the sensitivity of test methods |
ISO 19004:2004 describes how test sensitivity can be determined for test methods used to measure typical physical and chemical properties of rubber and rubber products. It is also applicable to tests used to measure the properties of carbon black fillers.
Test sensitivity is defined as the ratio of the discrimination power of a test method for the fundamental property to be determined to the measurement error expressed as a standard deviation. It is frequently described as the 'signal-to-noise ratio'.
The standard does not address the topic of sensitivity in the context of threshold (i.e. minimum) detection limits in the determination of very low or trace constituent levels.
ISO 19004:2004 is based, with permission of ASTM, on ASTM D 6600-00, Standard Practice for Evaluating Test Sensitivity for Rubber Test Methods, copyright ASTM.

Rubber — Determination of total sulfur content by ion chromatography |
ISO 19242:2015 specifies a method for the determination of the total sulfur content of raw rubber and unvulcanized or vulcanized rubber compounds by ion chromatography following the preparation of a sample solution using either a tubular furnace combustion or an oxygen combustion flask method.
The tubular furnace combustion method is applicable for rubbers with sulfur content less than 0,1 % as it is possible that the oxygen combustion flask method will not give sufficiently accurate results.
The oxygen combustion flask method is not applicable to rubbers containing a metal salt that forms an insoluble metal sulfate, such as barium sulfate.

Rubber — Determination of mass concentration of tire and road wear particles (TRWP) in soil and sediments — Pyrolysis-GC/MS method |
ISO/TS 21396:2017 specifies a method for the determination of the soil or sediment mass concentration (μg/g) of tyre and road wear particles (TRWP) in environmental samples.
ISO/TS 21396:2017 establishes principles for soil or sediment sample collection, the generation of pyrolysis fragments from the sample, and the quantification of the generated polymer fragments. The quantified polymer mass is used to calculate the concentration of TRWP in soil or sediment. These quantities are expressed on a TRWP basis, which includes the mass of tyre tread and mass of road wear encrustations, and can also be expressed on a tyre rubber polymer or tyre tread basis.
NOTE Tyre and road wear particles are a discrete mass of elongated particles generated at the frictional interface between the tyre and roadway surface during the service life of a tyre. The particles consist of tyre tread enriched with mineral encrustations from the roadway surface.

Rubber — Framework for assessing the environmental fate of tyre and road wear particles (TRWP) |
This document establishes a general framework and considerations for assessing the environmental fate of tyre tread chemical additives in cured polymer and tyre and road wear particles (TRWP) throughout a tyre lifecycle. This document is applicable to laboratory-generated TRWP from cured tread polymer of known composition.
Testing strategies are described for assessing the environmental fate and transport of tyre chemicals in the following processes that can occur during the tyre lifecycle:
a) transformation of chemical additives in tread during tyre curing;
b) transformation of chemical additives during TRWP generation (tyre use);
c) transformation of chemical additives during TRWP aging and weathering;
d) leaching of chemical additives and transformation products from TRWP to water;
e) availability of chemical additives and transformation products from TRWP in sediment ecosystems.
Mass concentrations and fractions of chemicals released or available from TRWP for the five lifecycle steps are used to estimate
a) cumulative fraction of tread chemical(s) and transformation product(s) released to water, and
b) cumulative fraction tread chemical(s) and transformation products(s) environmentally available.

Rubber, vulcanized or thermoplastic — Determination of resistance to abrasion using a driven, vertical abrasive disc |
ISO 23233:2009 specifies a method for the determination of the resistance of rubber to abrasion using a driven, vertical abrasive disc (the LAT 100: Laboratory Abrasion Tester 100).
The loss in mass on abrasion is determined through the slip caused by setting different slip angles and rotational speeds between a wheel-shaped rubber test piece and an abrasive disc, rotating in planes at right angles to each other and pressed against each other with a specified load. The test result can be reported as the loss in mass per unit running distance and/or as an abrasion resistance index compared to a reference compound.
This International Standard is applicable to comparative testing, quality control, specification compliance testing, referee testing and research and development work.
As the test device described is capable of setting each abrasion parameter, such as slip angle, rotational speed of the abrasive disc and load, independently, the method is suitable for carrying out a wide range of abrasion tests for various rubber products, especially tyres.

ISO 23337:2007 specifies a method for the determination of the resistance of rubber to abrasion using the Improved Lambourn test machine.
The abrasion loss resulting from the slip caused by the difference in circumferential speed between a disc-shaped rubber test piece and an abrasive wheel, which are driven to rotate independently with their circumferences pressed against each other by a specified load, is determined. The test result can be reported as the volume loss per unit time or per unit running distance, and/or as an abrasion resistance index compared to a reference compound.
As the Improved Lambourn test machine is capable of setting various abrasive conditions, such as slip rate, sliding speed and load, independently, this method is suitable for the evaluation, under a wide range of severity conditions, of compounds for a range of rubber products, especially tyres. An example of the testing of tyre tread rubber is given in an annex.

Rubber, vulcanized or thermoplastic — Determination of abrasion resistance using the Improved Lambourn test machine |
ISO 23337:2016 specifies a method for the determination of the resistance of rubber to abrasion using the Improved Lambourn test machine.
The abrasion loss resulting from the slip caused by the difference in circumferential speed between a disc-shaped rubber test piece and an abrasive wheel, which are driven to rotate independently with their circumferences pressed against each other by a specified load, is determined. The test result can be reported as a volume loss per abrasion test time or running distance, and/or as an abrasion resistance index compared to a reference compound.
As the Improved Lambourn test machine is capable of setting various abrasive conditions, such as slip rate, sliding speed and load, independently, this method is suitable for the evaluation of compounds for a range of rubber products, especially tyres, under a wide range of severity conditions. An example of the testing of tyre tread rubber is given in Annex A.

Rubber — Acquisition and presentation of comparable single-point data |
ISO 24453:2008 identifies specific test procedures for the acquisition and presentation of comparable single-point data for properties of rubber compounds. In general, each property is specified by a single test method and a single experimental value although, in certain cases, properties may be represented by more than one value obtained under different test conditions. The properties presented are those used to characterize processing properties, those most often quoted by manufacturers and in material specifications, and those relevant to more specific applications. An important application consists in helping different suppliers produce material specification sheets in which the same set of properties is measured using the same conditions.

Rubber, vulcanized — Measurement of fatigue crack growth rate |
ISO 27727:2008 specifies a method for the determination of the fatigue crack growth rate of vulcanized rubber under repeated loading over an extended period of time. The crack starts from the tip of a cut made in the test piece before the test, and grows progressively until it finally becomes large enough for complete fracture to occur. Using a pure-shear test piece, measurements are made to monitor the crack growth under the cyclic loading in order to obtain the crack growth rate, i.e. the increase in crack length per cycle. Tests are carried out at various tearing energies by varying the strain energy density in the test piece. This is done by changing the strain amplitude.

The methods are applicable to the determination of the volatile-matter content in the "R" group of rubbers listed in ISO 1629. These are rubbers having an unsaturated carbon chain, for example natural rubber and synthetic rubbers derived at least partly from diolefins. The methods can also be applicable to other raw rubbers, but in these cases it is necessary to demonstrate that the change in mass is due solely to loss of actual volatile matter and not to rubber degradation.
The hot-mill method is not applicable to natural rubber, to synthetic rubbers which are too difficult to handle on a hot mill or to synthetic rubbers in powder or chip form.
The applicability of each test method to various types of rubber is summarized in an annex.

These methods might also be applicable to other raw rubbers only when the change in mass is proven to be due solely to loss of original volatile matter and not to rubber degradation.
1.3 The methods are not applicable to raw rubbers which need homogenizing as specified in ISO 1795.
1.4 The hot-mill method and the oven method specified in ISO 248‑1 and the methods specified in this document might not give identical results. In cases of dispute, therefore, the oven method, procedure A, specified in ISO 248‑1:2011, is the referee method.
NOTE These methods can be useful for routine determinations, e.g. quality control, when the measurement conditions for the automatic analyser are fixed for a particular raw rubber or grade of raw rubber.

Rubber, raw — Determination of volatile-matter content |
ISO 248:2005 specifies two methods, a hot-mill method and an oven method, for the determination of moisture and other volatile-matter content in raw rubbers.
These methods are applicable to the determination of the volatile-matter content in the R-group of rubbers listed in ISO 1629 which are rubbers having an unsaturated carbon chain, for example, natural rubber and synthetic rubbers derived at least partly from diolefins.
ISO 248:2005 may also be applicable to other rubbers, but in these cases it is necessary to prove that the change in mass is due solely to loss of original volatile matter and not to rubber degradation.
The hot-mill method is not applicable to natural and synthetic isoprene rubbers or to rubbers too difficult to handle on a hot mill or to rubbers in powdered or chip form.
