Test methods for determining the contribution to the fire resistance of structural members - Part 11: Applied protection to solid steel bars in tension based on mechanically loaded fire tests

This document describes the test and assessment procedure for determining the contribution of reactive fire protection systems to the fire resistance of solid steel bars used as tension members, when exposed to the standard temperature/time curve specified in EN 1363-1. In special circumstances, where specified in National Building Regulations, there can be a need to subject reactive fire protection systems to a slow heating curve (smouldering fire) as defined in EN 1363-2. The corresponding test and assessment procedure are described in Annex E. The fire protection performance is determined by testing mechanically loaded steel bars in horizontal orientation. Information regarding the testing of additional unloaded specimens is given to assess the influence of the bar orientation and smouldering fire behaviour. The principles of the testing and assessment procedure can also be applied for other section shapes such as angles, channels and flats. This document does not include steel bars used as reinforcement in concrete construction. The document is applicable to steel bars up to a maximum diameter of 130 mm. In the case of rectangular bars, the maximum edge length shall be limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter edge length. The test programme and the assessment are designed to cover: - a range of valid fire protection classification periods; - a range of thickness of the applied reactive fire protection system; - a range of steel bar dimensions and profiles; - a range of specified design temperatures; - a range of load utilisation factors in case of fire; - a range of bar orientation. This document also provides the assessment procedure, which prescribes how the analysis of the test data shall be made and gives guidance on the procedures by which interpolation shall be undertaken. The assessment procedure is used to establish: a) on the basis of data derived from mechanically loaded testing steel bar, any practical constraints on the use of the reactive fire protection system under fire test conditions (the physical performance); b) on the basis of the temperature data derived from testing steel bar the thermal properties of the reactive fire protection system (the thermal performance). The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes over the range of thicknesses of the applied reactive fire protection system tested.

Testing of ceramic materials - Determination of sulfur in non-oxidic ceramic raw materials and ceramic materials - Part 1: Infrared measurement methods (ISO/DIS 14720-1:2025)

ISO 14720-1:2013 defines a method for the determination of sulfur in powdered and granular non-oxidic ceramic raw materials and materials, such as silicon carbides, silicon nitrides, graphites, carbon blacks, cokes, carbon powders. If proved by the recovery rate, this method can also be applied for other non-metallic powdered and granular materials, e.g. silicon dioxide. ISO 14720-1:2013 is applicable for materials with mass fractions of sulfur from 0,005 % to 2 %. ISO 14720-1:2013 can also be applied for materials with higher mass fractions of sulfur after verification of the particular case.

Leather - Raw bovine hides and skins - Description, presentation and preservation

This document specifies the following for raw bovine hides and skins intended for use throughout the leather manufacturing supply chain: - Terms and definitions; - Rules for the presentation of raw hides and skins. It applies to fresh and salted bovine hides and skins. It is not the aim of this document to interfere with the normal commercial agreement between the buyer and the supplier of hides and skins, on the contrary, it should be able to be used as a basis. This document is intended to avoid disagreements between parties. It is the result of discussions with representatives of agriculture, slaughterhouses, skin trade and tanneries. It shows which parts of hides and skins can be used for leather production and which factors influence the quality of hides and skins. Furthermore, it gives recommendations on precautions to be taken for transport, preservation, loading and unloading, selection of tanned hides, classification of hides, weight, loss and tax exemption, identification of hides.

Testing of ceramic materials - Determination of sulfur in non-oxidic ceramic raw materials and ceramic materials - Part 2: Inductively coupled plasma optical emission spectrometry (ICP-OES) or ion chromatography (IC) after burning in the oxygen flow (ISO/DIS 14720-2:2025)

This part of ISO 14720 defines a method for the determination of sulfur in powdered and granular non-oxidic ceramic raw materials and materials, which are completely oxidized at a higher temperature in an oxygen atmosphere, e.g. carbon and graphite materials. For materials which are not completely oxidizable under these conditions, it is possible to determine sulfur that can be released under these conditions, e.g. the adherent sulfur. This part of ISO 14720 is applicable for materials with mass fractions of sulfur ≤ 10 % and mass fractions of ash < 20 %, The defined method is limited for materials with mass fractions of barium < 10 mg/kg, because the sulfur bonded in barium sulfate is not detectable with this method. For the lower detection limit of this method, a mass fraction of sulfur of 0,5 mg/kg in the case of inductively coupled plasma optical emission spectrometry (ICP/OES) and 5 mg/kg in the case of ion chromatography (IC) has to be considered as a recommended value.
