This document specifies a method to determine the resistance to slow crack growth (SCG) of thermoplastic materials, pipes, and fittings. The test is applicable to samples taken from compression moulded sheets, extruded rods, sheets or pipes and injection moulded fittings of suitable thickness. This document provides a method that is suitable for an accelerated fracture-mechanics characterization at ambient temperatures of 23 °C. This document specifies test parameters for polyethylene (PE), polypropylene (PP) and unplasticized polyamide (PA-U). Furthermore, this test can be applied to characterise the slow crack growth resistance of virgin, as well as non-virgin (reused, recycled) thermoplastic materials.[5] This test method can be adapted for other thermoplastics materials by developing the procedure using different test parameters.

 

This standard provides requirements and guidelines on applying model-based testing (MBT) following the test processes defined in ISO/IEC/IEEE 29119-2. This document covers the following areas: Using MBT, the generation of a test case is systemized and automated. This standard assumes that test execution is also automated. The implementation of the generation algorithm is tool-dependent and, therefore, is out of the scope of this document. MBT tool selection is also out of the scope of this document. The test models and the information generated by the supporting MBT tools can be used, in part or whole, to satisfy the documentation requirements of ISO/IEC/IEEE 29119-3. Many MBT tools implement one or more test techniques and associated measures defined in ISO/IEC/IEEE 29119-4. These techniques are associated with individual tool implementation and are outside the scope of this document. This standard applies to MBT in all development lifecycle models.

 

 

This document defines a framework for the development of built environment information structures. The framework is a breakdown structure supporting the spatial, physical, process aspects along with relevant resources and support. This framework provides a set of recommended titles for classification structures for a range of information object groupings according to particular views, supported by definitions. This document applies to the complete life cycle of assets. It applies to both building and civil engineering work, including associated engineering services, landscaping and its natural environment. It is intended for use by organizations which develop and publish such classification structures and tables. This document aims to facilitate the harmonization of local classification structures and tables during their development. The management of the built environment above the level of complexes, entities and projects/programmes is outside the scope of this document. This document gives possible examples for the content of the tables. It also provides examples of current classification structures.

To articulate and present the semantic data model effectively, this document leverages the following standards: The initial edition of this semantic data model focuses on specifying object classes and their attributes and associations. These specifications are aligned with the functional requirements outlined in ISO 21378:2019, Audit Data Collection.

 

This document describes a method for determining the unidirectional apparent chloride diffusion coefficient and surface concentration of conditioned specimens of hardened concrete. The test method enables the determination of the chloride penetration after a specified length of curing and length of exposure to NaCl solution. Since resistance to chloride penetration depends on ageing which includes the effects of continual hydration and interactions with the chloride solution, then the apparent diffusion coefficient also changes with age. A procedure to determine this ageing, expressed here by an ageing exponent, is included in this document and described in Annex A. The test procedure does not apply to concrete with surface treatments such as silanes and it does not apply to concrete containing fibres (see E.1).

 

This document specifies a method of determining the carbonation rate of a concrete, expressed in mm/va. This document establishes a procedure where a standardized climate controlled chamber is used and where specimens are placed on a natural exposure site protected from direct rainfall. The standardized climate controlled chamber procedure is the reference method. These procedures are applicable for the initial testing of concrete, including those manufactured with slowly reacting binders, provided that the ages at which the carbonation depth is measured, the number of measurements required to calculate the carbonation rate, as well as the length of exposure to CO2, are appropriately selected, as described in this document. These procedures are not applicable for factory production control.

 

This document specifies procedures to determine the thermal resistance of products whose thicknesses exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. Most of the procedures described in this standard require apparatus that allows tests on specimens up to 100 mm thick . This document gives guidelines to assess the relevance of the thickness effect, i.e. to establish whether the thermal resistance of a thick product can or cannot be calculated as the sum of the thermal resistances of slices cut from the product, these guidelines complement the indications given in ISO 8302:1991[1] on the guarded hot plate apparatus. This document describes testing conditions which prevent the onset of convection which could take place in some products under the considered temperature differences and thicknesses.

 

This document describes a method for evaluating the carbonation resistance of concrete using test conditions that accelerate carbonation. After a defined period of curing and a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide. NOTE The test performed under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to curing under water of 28 days, a minimum preconditioning period of 14 days and an exposure period to increased carbon dioxide level of 70 days. This procedure is not a method for the determination of carbonation depths in existing concrete structures.

 

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of dry test specimens having a thermal resistance of not less than 0,5 m2·K/W. NOTE 1 The above limit is due to the effect of contact thermal resistances. An upper limit for measurable thermal resistance depends upon a number of factors described in this document, but a unique figure cannot be assigned. It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C. NOTE 2 Limits to the mean test temperature are only imposed by the materials used in the apparatus construction and by ancillary equipment. This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect). This document does not apply to cover measurements on moist products of any thermal resistance or measurements on thick products of high and medium thermal resistance.

 

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m2·K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2,0 W/(m·K). NOTE The lower limit for measurable thermal resistance is due to the effect of contact thermal resistances, which require special testing techniques described in this document. Although this document can be used for testing dry specimens of high and medium thermal resistance, i.e. on products having a thermal resistance, that is, on products with a thermal resistance of at least 0.5 m².K/W, the simpler procedures of EN 12667[3] are available for such specimen. This document does not cover methods to assess the hygrothermal transmissivity of materials in the over-hygroscopic range (i.e. when free liquid water occurs in the material in general above 95% of moisture). It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C. This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, suggested materials for vapour-tight envelopes when testing moist specimens, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect).

 

This document specifies the functional requirements for rail vehicle windscreens, including type testing, routine testing, and inspection methods for main line railway systems and urban guided transport. This document applies to windscreens made of laminated glass, which is the most commonly used material but also to other materials, subject to the performance requirements being satisfied. For on-track machines (OTMs) when in transport mode (self-propelled or hauled) the requirements of this standard are applicable. OTMs in working configuration are outside the scope of this document. Determination of the size, shape, orientation, and position of windscreens is outside the scope of this document. This document does not specify requirements for the interfaces between the windscreen and the vehicle. Accordingly this document does not address issues relating to installation, structural integrity, and crashworthiness.

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).
