This document is published as a dual log standard and provides guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gas-air mixtures or vapour-air mixtures under normal conditions of temperature and pressure (20 °C, 101,3 kPa) so as to permit the selection of an appropriate group of equipment. This document also describes a test method intended for use in the determination of the auto-ignition temperature (AIT) of a vapour-air mixture or gas-air mixture at atmospheric pressure, so as to permit the selection of an appropriate temperature class of equipment. Values of chemical properties of materials are provided to assist in the selection of equipment to be used in hazardous areas. Further data may be added as the results of validated tests become available. The materials and the characteristics included in a table (see Annex B) have been selected with particular reference to the use of equipment in hazardous areas. The data in this document have been taken from a number of references which are given in the bibliography. These methods for determining the MESG or the AIT may also be used for gas-air-inert mixtures or vapour-air-inert mixtures. However, data on air-inert mixtures are not tabulated. Keywords: classification of gases and vapours, measurement of the maximum experimental safe gaps (MESG)

 

This document specifies definitions, principles of construction, requirements and methods for testing the performance of UV devices (240 nm to 290 nm nominal) for potable water installations according to EN 806-2 which are permanently connected to the building’s supply. Devices described by this document can be installed at the point of entry (POE), within the water distribution system inside the building or at the point of use (POU).

This document specifies the design, minimum safety requirements, and inspection and testing procedures for liquefied hydrogen (LH2) marine transfer arms intended for use at onshore LH2 terminals handling LH2 carriers. It also covers the minimum requirements for safe LH2 transfer between ship and shore. Although the requirements for power/control systems are covered, this document does not include all of the details for the design and fabrication of standard parts and fittings associated with transfer arms. This document is mainly focused on hard pipe type transfer systems; hose type transfer systems are not described in detail in the general description of this document. However, hose type transfer systems can also be considered as reasonable vacuum insulated technology for the design of transfer arms for liquefied hydrogen.

 

ISO 14114:2017 applies to acetylene cylinder manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve.

This document describes a test method for the determination of the fracture toughness of monolithic ceramic thin plates at room temperature by the single-edge precracked plate method or the single-edge V-notch plate method. This document is intended for use with monolithic ceramics and whisker- or particulate-reinforced ceramics which are regarded as macroscopically homogeneous. It does not include continuous-fibre-reinforced ceramics composites. This document is applicable to ceramic thin plates with a thickness of 0,2 mm to =1,0 mm. The single-edge V-notch plate method can be applied to monolithic ceramics with a grain size larger than about 1 µm. The use of this method is inappropriate for yttria tetragonal zirconia polycrystal material (Y-TZP), which consists of homogeneous fine submicron grains. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch. This document is applicable for material development, material comparison, quality assurance, characterization, reliability and design data generation. The Scope clause is a mandatory element of the text. For rules on the drafting of the Scope, refer to the ISO/IEC Directives, Part 2:2018, Clause 14.
