This document specifies a method to determine the plasticity retention index (PRI) of raw natural rubber. The PRI is a measure of the resistance of raw natural rubber to thermal oxidation. A high resistance to thermal oxidation is shown as a high value of the index. PRI is not an absolute value and cannot give an absolute classification of plasticity number of different natural rubber after oxidation.

This document specifies three methods to determine the permeability to gas by measuring the volume of gas diffusing through a rubber or plastics hose or length of tubing used for gas applications in a specified time.
— Method 1 is for determining the permeability of the complete hose wall or length of tubing wall, excluding end fittings, to the test gas.
— Method 2 is for determining the permeability at the hose and fitting interface to the test gas.
— Method 3 is for precisely determining the permeability of the complete hose or length of tubing, including end fittings.

This document specifies methods for calculating the resin, fibre and void contents of a carbon-fibre-reinforced composite from the densities of the resin, the fibre and the composite and the mass of fibre in the composite (using method A), for calculating the fibre content from the thickness of the composite (using method B), and for calculating the fibre content by volume and areal void content through microscopic analysis (using method C). Method A specifies three different resin removal procedures for the determination of the mass of fibre in the composite (viz a combustion procedure, a procedure by digestion in nitric acid and a procedure by digestion in a mixture of sulfuric acid and hydrogen peroxide). The selection of the procedure to be used is made by considering the combustibility of the resin used in the composite, its ability to decompose and the type of resin concerned. Method A is only of limited applicability when filled resins are present that can prevent complete dissolution and/or combustibility of the resin. Method B (thickness measurement method) is only applicable to composites moulded from prepregs of known fibre mass per unit area. Method C (microscopic method) is only applicable to carbon-fibre-reinforced composites with unidirectional, orthogonal and multidirectional laminates. It can also be used as reference for determination of the areal void content and fibre volume content of aramid- or glass-fibre-reinforced plastics, but is not applicable to fabric reinforced composites.

This document specifies the procedures intended for use in estimating the resistance of vulcanized or thermoplastic rubbers to cracking when exposed, under static or dynamic tensile strain, to air containing a definite concentration of ozone, at a definite temperature and, if required, at a definite relative humidity in circumstances that exclude the effects of direct light. Either visual observation or image analysis, or both, are used to evaluate the formation and growth of cracks. The changes in physical or chemical properties resulting from exposure can also be determined. Reference and alternative methods for determining the ozone concentration are described in ISO 1431-3.

This document specifies a method for the determination of the static vulcanized adhesion strength of rubber compounds to rigid materials. The test piece is composed of two conical ends of the rigid material, joined by a cylinder of rubber. The adhesion is obtained by a bonding system which can include not only the rigid material and the rubber compound, but other elements such as thin alloy coatings or chemical treatments of rigid parts and either a single cement or both primer and cover cements. The bonding system for preparing the test pieces should be adequately specified by the user, but a provision is made in this document for the evaluation of different types of failure related to a complex bonding system. The method is designed primarily for test pieces prepared in the laboratory under standard conditions in order to provide data for development and control of bonding systems and their components, such as cements or special rubber compounds, and of methods of manufacture. While intended to be applied where the rubber is bonded to rigid supporting pieces, it can be inapplicable such cases where the support, although of high-modulus material, has a low rigidity due to small transverse dimensions, as in the case of rubber bonded to metal wires, cords or thin sheets.

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.

This document specifies two procedures for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature. The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one. Two test methods are specified, method A and method B. In method A the compression and all measurements of counterforce are made at test temperature and in method B the compression and all measurements of counterforce are made at standard laboratory temperature. Method A and method B do not give the same results, as in method B the shrinkage of the material from the test temperature to standard laboratory temperature is included in the result. Two forms of test piece are specified in this document: cylindrical test pieces and rings. Comparison of results is valid only when made on test pieces of similar size and shape. The use of ring test pieces is particularly suitable for the determination of stress relaxation in liquid environments. This document deals only with testing at constant ambient or elevated temperature. Testing at temperatures below standard laboratory temperature is not specified. The methods have been used for low‑temperature testing, but their reliability under these conditions is not proven.
