This document specifies the requirements for rubber hoses and hose assemblies, up to a maximum hose size of 19, for use in motor vehicles with liquefied petroleum gas (LPG) installations. The hoses are designed for use up to a maximum working pressure of 3,0 MPa (30 bar) and at working temperatures from −40 °C up to and including +80 °C.

This International Standard specifies the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use, with repeated opening and closure. It does not specify the ability of valves to withstand adverse conditions, in particular those of chemically aggressive fluid media and/or environments, or excessive fluid velocities and cavitation.

NOTE For what concern the chemical aggression of the materials, a classification table is reported in ISO TR 10358[1].

This International Standard includes values of the parameters necessary for the proper performance of the endurance test, with the reservation that parameters may be different in particular product standards (see 5.1).

unplasticized poly(vinyl chloride) (PVC-U) profiles with light coloured surfaces intended to be used for the fabrication of windows and doors.

It is applicable to PVC-U profiles with the colorimetric co-ordinates measured on the visible surfaces, as follows:

L* ≥ 82 (chromaticity co-ordinate Y ≥ 60),

— –2,5 ≤ a* ≤ 5,

— –5 ≤ b* ≤ 15.

NOTE 1 For editorial reasons in this document the term "window" is used for window/door.

NOTE 2 Profiles made from PVC-U materials with reinforcements (e.g. glass fibres) are not part of this scope.

This part of ISO 19095 specifies the principles for characterize the toughness for the adhesion interface performance in plastic-metal dissimilar joints in terms of the critical-stress-intensity factor, KIC, and the critical energy release rate, GIC, at fracture initiation. This test method is to provide a quantitative way of expressing a materials resistance to failure of the interface when a delaminated area or pre-crack is present at interface using compact tensile (CT) geometries.

The scheme assumes linear elastic behavior of the plastic-metal joint specimen with a delaminated area, so certain restrictions on linearity of the load-displacement diagram are imposed.

The significance of this test method and many conditions of testing are identical to those of ISO 13586 for the determination of fracture toughness of plastic materials, and, therefore, appear here with many similarities. However, certain specifications and conditions in terms of the plastic-metal joint specimens not covered in ISO 13586 are included.

This document specifies a test based on hardness measurements for determining the progressive stiffening of rubber with time, caused by crystallization. It is limited to materials having an initial hardness at a test temperature of from 10 IRHD to 85 IRHD.

The method is applicable to raw, unvulcanized (compounded) and vulcanized rubber. It is mainly of interest for rubber with a marked crystallization tendency at temperatures experienced in cold climates, such as chloroprene and natural rubber.

The method is not applicable to fast-crystallizing materials which crystallize to a considerable degree within the time-span of 15 min used for conditioning at test temperature.

This document specifies a method using a shear test apparatus for measuring the in-plane shear stress/shear strain response, shear modulus and shear strength of continuous-fibre-reinforced plastic composite materials with fibre orientations of 0° and 0°/90°.

This method is applicable to thermoset and thermoplastic matrix laminates made from unidirectional layers/non-woven fabrics and/or fabrics including unidirectional fabrics, with the fibres oriented at 0° and 0°/90° to the specimen axis, where the lay-up is symmetrical and balanced about the specimen mid-plane.

The method is suitable for determining shear properties in both the linear and nonlinear load-deformation range even at shear strains greater than 5 %.

Short and long fibre-reinforced plastic composites can also be tested using this document.

The vocabulary is limited to those terms in general use throughout the rubber industry.

It does not define terms intended for particular rubber products, some of which are given in the vocabulary standards listed in the Bibliography.

It does not define terms that are generally understood or adequately defined in other readily available sources such as general dictionaries.

The terms are listed in the alphabetical order of the English terms, with a French index to the corresponding English terms attached. Some terms have parenthetical information added to indicate a specific limitation of the term to a particular field, for example “〈ubber latex〉”. When a term has one or more synonyms, the synonymous terms follow the preferred term.

Deprecated terms are indicated by “DEPRECATED”.

Symbols are included under their full descriptions, but for convenience they are also listed separately at the end of the main text.

For convenience, standards and other relevant sources referred to in this vocabulary are listed in the first section of the Bibliography and vocabularies relating to finished rubber products are listed in the second section.
