It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127.

This International Standard establishes a system of symbols for the basic rubbers in both dry and latex forms, based on the chemical composition of the polymer chain. The purpose of this International Standard is to standardize the abbreviated terms used in industry, commerce, and government, and it is not intended to conflict with, but rather to act as a supplement to, existing trade names and trademarks.

This document specifies a test method for determining the interfacial shear strength between a single fibre and a matrix by means of a pull-out test. The method can be used to measure the critical energy release rate. The method is applicable to reinforcement fibres such as carbon fibres, glass fibres, basalt fibres and similar stiff reinforcement fibres and to thermoset, thermoplastic and fine-grained concrete matrices. It can be used for polymeric reinforcement fibres and for other inorganic matrices. It is not applicable to:

This International Standard specifies the test method to determine the open-hole compressive strength of laminated fibre-reinforced plastic composites. The laminate is intended to be a balanced and symmetrical lay-up or be otherwise homogeneous through the thickness. This International Standard applies to all textile diameter fibre types (carbon, glass, aramids, etc.) and matrices (e.g. thermoset, thermoplastic) that meet the requirements of this International Standard. This International Standard includes three methods: Method 1 employs an L-shaped base fixture and two end fixtures. These end fixtures are compressed between the platens of the test machine. Method 2 employs end supports similar to the fixtures given in C.1 of ISO 14126:1999. Method 2 is useful for cyclic loading conditions test, including under fully or partly reversed loading conditions when the specimen is clamped by hydraulic grips without support fixtures Method 3 has two types of loading methods, i.e. 3A and 3B. In method 3A, the specimen is placed within a stabilization fixture, which is then clamped by hydraulic grips. In method 3B, the specimen is placed within a stabilization fixture and then end-loaded by platens. Full details of test methods 3A and 3B are given in ASTM D6484/D6484M-09, procedure A and procedure B, respectively.

This International Standard specifies a method for the assessment of the resistance to cold liquids of all rigid furniture surfaces regardless of materials. It does not apply to leather and textile surfaces. The test is intended to be carried out on a part of the finished furniture, but can be carried out on test panels of the same material, finished in an identical manner to the finished product, and of a size sufficient to meet the requirements of the test. The type and number of test liquids (Annex A) and the test periods (Table 1) shall be stated in requirement specifications or shall be agreed upon between purchaser and supplier or interested parties. Annex A (normative) includes a selection of suitable test liquids. Other liquids can be used if required.

The ISO 10350 series identifies specific test procedures for the acquisition and presentation of comparable data for certain basic properties of plastics. In general, each property is specified by a single experimental value, although in certain cases properties are represented by two values obtained under different test conditions. The properties included are those presented conventionally in manufacturers' data sheets. This document applies predominantly to unreinforced and reinforced thermoplastic and thermosetting materials that may be injection- or compression-moulded or prepared as sheets of specified thickness.

This document establishes a system of designation for profiles made of unplasticized poly (vinyl chloride) (PVC-U) intended to be used for building applications. This part is applicable to light coloured and coloured PVC-U profiles, obtained by a mono-extrusion or a co-extrusion process, with or without surface finishing (e.g. laminated foil, paint, printing process). It specifies test methods and test parameters. This method of designation is intended to be used in product specification when the application is specified. Profiles for the management of electrical power cables, communication cables and power track systems used for the distribution of electrical power, profiles for windows or doors and profiles for guttering are not covered by this document . NOTE It is intended to use this method for the designation of PVC-U profiles for information related to technical literature of the manufacturer, not for the marking of the products.
