The method of classification given in this part of ISO 4433 serves to determine the chemical resistance of polyolefin pipes, fittings and valve components designed for the conveyance of chemicals in the absence of pressure and stress such as earth loads, dynamic internal stresses. To determine the chemical resistance, the method uses the change in mass and the changes in tensile properties which result from the storage of test pieces, taken from such pipes, fittings and valve components, in chemicals. The test is carried out in accordance with ISO/DIS 4433-1. This part of ISO 4433 is also applicable to polyolefin sheets as appropriate.

 

This part of ISO 4433 specifies a method for carrying out a preliminary evaluation of the behaviour of thermoplastics pipes, fittings, sheets and valve components in relation to the chemicals transported. This method provides information on the suitability of pipes, fittings, sheets and valve components for transporting chemicals in the absence of pressure or stresses such as earth loads, dynamic stresses and internal stresses. NOTE An additional indication about test method to evaluate the compatibility of plastic materials against liquids, gases, their mixtures or multiphase fluids is reported in ISO 23936-1[11]. A full procedure for carrying out the test is also reported in ISO 175, which is devoted to plastics in general, and not specifically to thermoplastics pipes, fittings, sheets and valve components. Fatigue resistance, permeability, resistance to rapid gas decompression are not taken into account in this document.

This document defines quality measures for quantitatively evaluating product quality in terms of characteristics and subcharacteristics defined in ISO/IEC 25010 and is intended to be used together with ISO/IEC 25010. It can be used in conjunction with the ISO/IEC 2503n and the ISO/IEC 2504n standards or to more generally meet user needs concerning ICT products and software products quality. This document contains a basic set of quality measures for each characteristic and subcharacteristics. It includes, as informative annexes, considerations for the use of quality measures (Annex A), QMEs used to define product or system quality measures (Annex B), and a detailed explanation of measurement types (Annex C). This document does not provide the specific ranges of values of the measures to rated levels or grades of compliance because these values are determined based on the nature of the system, product, or a part of the product, and depending on factors such as the category of the software, integrity level, and users’ needs. Some attributes could have a desirable range of values, which does not depend on specific user needs but depends on generic factors; The proposed quality measures are primarily intended to be used for quality assurance and improvement of products during or post the development life cycle process. The main users of this document are people carrying out quality requirement specification and evaluation activities as part of the following: — development: including requirements analysis, design specification, coding, and testing through acceptance during the life cycle process; — quality management: systematic examination of the software product or computer system, for example, when evaluating system or software product quality as part of quality assurance, quality control, and quality certification; — supply: a contract with the acquirer for the supply of a system, software product, or software service under the terms of a contract, for example, when validating quality at qualification test; — acquisition: including product selection and acceptance testing, when acquiring or procuring a system, software product, or software service from a supplier; — maintenance: improvement of the software product or system based on quality measurement.

This document specifies a method for determining the flexural properties of rigid and semi-rigid plastics under defined conditions. A preferred test specimen is defined, but parameters are included for alternative specimen sizes for use where appropriate. A range of test speeds is included. The method is used to investigate the flexural behaviour of the test specimens and to determine the flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship under the conditions defined. It applies to a freely supported beam, loaded at midspan (three-point loading test). The method is suitable for use with the following range of materials: — thermoplastic moulding, extrusion and casting materials, including filled and reinforced compounds in addition to unfilled types; rigid thermoplastics sheets; — thermosetting moulding materials, including filled and reinforced compounds; thermosetting sheets. In agreement with ISO 10350-1[5] and ISO 10350-2,[6] this document applies to fibre-reinforced compounds with fibre lengths =7,5 mm prior to processing. For long-fibre-reinforced materials (laminates) with fibre lengths >7,5 mm, see ISO 14125[7]. The method is not normally suitable for use with rigid cellular materials or sandwich structures containing cellular material. In such cases, ISO 1209-1[3] and/or ISO 1209-2[4] can be used. NOTE 1 For certain types of textile-fibre-reinforced plastic, a four-point bending test is used. This is described in ISO 14125. The method is performed using specimens which can be either moulded to the specified dimensions, machined from the central section of a standard multipurpose test specimen (see ISO 20753) or machined from finished or semi-finished products, such as mouldings, laminates, or extruded or cast sheet. The method specifies the preferred dimensions for the test specimen. Tests which are carried out on specimens of different dimensions, or on specimens which are prepared under different conditions, can produce results which are not comparable. Other factors, such as the test speed and the conditioning of the specimens, can also influence the results. NOTE 2 Especially for injection moulded semi-crystalline polymers, the thickness of the oriented skin layer, which is dependent on the moulding conditions, also affects the flexural properties. The method is not suitable for the determination of design parameters but can be used in materials testing and as a quality control test.

 

This test method covers the determination of the low-rate fracture toughness (JIc) of plastics exhibiting a ductile behaviour and characterized by a macroscopically stable crack growth during a fracture test. The application of standard LEFM tests to these materials typically fails due to the excessive non-linearity in the response. This test method, developed for the SEN(B) testing configuration, describes a single-specimen approach that does not require the measurement of ?a. Not intended to provide a method to construct the material JR curve, this test method allows checking a priori the applicability of the multi-specimen approach based on the ?a measurement for the construction of the material JR curve to a ductile polymer with given specimen geometry and dimensions. This is done by referring to a specially developed crack propagation parameter, which is labelled mS.
