This document describes the procedures for assessing the overall change in appearance of textile floor coverings caused by the Vettermann drum according to ISO 23106 and EN 18320, Hexapod tumbler test according to ISO 23122 and Castor chair test according to ISO 4918.

 

ISO 9405:2015 describes the procedures for assessing the overall change in appearance of textile floor coverings caused by Vettermann drum and hexapod tumbler testers according to ISO 10361 and ISO 4918.

 

This document describes procedures that use the mechanical action of a Vettermann drum tester using polyurethane studs to produce changes in appearance (surface structure and colour) to all types of textile floor coverings. It does not include pilling or colour changes due to other actions. Changes produced by this drum tester are assessed in accordance with the applicable assessment standard.

 

This document specifies the general terms and definitions relevant to the utilization of thermoplastics materials in a circular economy in pipes, fittings and ancillaries for both pressure and non-pressure piping systems. This document is intended to be used by specification writers in conjunction with CEN/TS 14541-2 [7] when preparing normative documents under the scope of CEN/TC 155.

 

The classification method in this part of ISO 4433 is used to determine the chemical resistance of pipes, fittings and valve components made of PVC-U, PVC-HI, PVC-M, PVC-A, PVC-O and PVC-C designed for the transport of chemicals in the absence of pressure and stresses, such as earth loads and dynamic internal stresses. To determine chemical resistance, the method uses the change in mass and changes in tensile properties that result from storing test pieces, taken from such pipes, fittings and valve components, in chemicals. The test is performed in accordance with ISO 4433-1. This part of ISO 4433 is also applicable to PVC-U, PVC-HI, PVC-M, PVC-A, PVC-O and PVC-C sheets, as appropriate.

 

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.

 

The method of classification given in this part of ISO 4433 serves to determine the chemical resistance of PVDF and ECTFE pipes, fittings and valve components designed for the conveyance of fluids in the absence of pressure and stress (e.g. due to earth loads or traffic loads, dynamic or 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 in chemicals. The storage test is carried out in accordance with ISO/DIS 4433-1. This part of ISO 4433 is also applicable to PVDF and ECTFE 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 gives requirements for the design, fabrication, inspection, testing and verification of GRP tanks and vessels with or without thermoplastics lining for storage or processing of fluids, factory made or site built, non-pressurized or pressurized up to 10 bar, for use above ground. Further requirements are presented in normative Annex G. The terms vessels and tanks as used in this document include branches up to the point of connection to pipe work or other equipment by bolting and supports, brackets or other attachments bonded directly to the shell. Fatigue is not considered a design criterion, as keeping strains below the limit strain inherently prevents fatigue failure. This document is applicable to vessels and tanks exposed to temperatures between -40 °C and 120 °C. This document does not apply to: - tanks and vessels for the transport of fluids; - underground storage tanks; - spherical vessels; - vessels and tanks of irregular shape; - tanks and vessels with double containment where the double wall is considered structural; - tanks and vessels which are subject to the risk of explosion, or failure of which can cause an emission of radioactivity; - specification for fibre reinforced cisterns of one piece and sectional construction for the storage, above ground, of cold water (see EN 13280).

 

This document specifies the definitions and requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems in the field of non-pressure underground drains and sewers for wastewater. NOTE 1 Products complying with this document can also be used in non-pressure underground drains and sewers for surface water. This document also specifies test methods and test parameters. This document is applicable to: - solid wall pipes and fittings which are intended to be used buried underground outside the building structure reflected in the marking of the products by “U”, and - solid wall pipes and fittings which are intended to be used buried underground both outside (application area code “U”) and within the building structure reflecting on the marking of products by “UD”. NOTE 2 Multilayer pipes with different formulations throughout the wall and foamed core pipes are covered by EN 13476-2 [1]. This document covers a range of pipe and fitting sizes, stiffness classes, and gives recommendations concerning colours. NOTE 3 It is the responsibility of the purchaser or specifier to make the appropriate selection from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes. In conjunction with CEN/TS 1401 2 [7] it is applicable to PVC-U pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended for buried piping systems for non-pressure underground drains and sewers. NOTE 4 Pipes, fittings and other components conforming to any of the plastics product standards listed in Annex C can be used with pipes and fittings conforming to this document, provided they conform to the requirements for joint dimensions given in Clause 10 and to the requirements of Table 16.

 

The method of classification given in this part of ISO 4433 serves to determine the chemical resistance of unplasticized polyamide (PA-U) pipes, fittings and valve components designed for the conveyance of fluids in the absence of pressure and stress (e.g. due to earth loads or traffic loads, dynamic or 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[1] and ASTM F 3524[2] that provides derating factor for hydrocarbons where the test method is shown by the publication[3] in the bibliography. 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 4433-1.
