This International Standard specifies the characteristics of liquid hydrogen refuelling and dispensing systems on land vehicles of all types in order to reduce the risk of fire and explosion during the refuelling procedure and thus to provide a reasonable level of protection from loss of life and property.

This International Standard is applicable to the design and installation of liquid hydrogen (LH2) fuelling and dispensing systems. It describes the system intended for the dispensing of liquid hydrogen to a vehicle, including that portion of the system that handles cold gaseous hydrogen coming from the vehicle tank, that is, the system located between the land vehicle and the storage tank.

This document classifies denture adhesives used by wearers of removable dentures; it also specifies requirements, test methods and instructions to be supplied for the use of such products. This document is applicable to denture adhesives for use by the consumer and excludes the dental lining materials prescribed or applied by dental professionals.

This document defines terms for use in connection with the production and use of reference materials including certified reference materials.

This document describes test methods and methods for classification of wood and wood-based products for which a stage in the production process results in an improvement of the reaction-to-fire classification in accordance with EN 13501-1 for use in interior and exterior situations (use classes 1, 2, and 3 as defined in EN 335:2013). NOTE The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood or wood-based product will last. This document applies to - wood and wood-based products (specific wood species, wood treated with preservatives and modified wood, for example thermally and chemically modified wood) that have been treated with fire-retardant chemical(s) applied either by a penetrating process or by a superficial process, such as with a film forming fire-retardant coating. - wood-based products that incorporate fire retardant chemical(s) as part of the production process. This document also covers fire-retardant wood and wood-based products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood and wood-based products are not covered by this document. NOTE 2 This document is relevant for, but not limited to, products covered by these products standards: EN 13986, EN 14081-1, EN14374, EN 14915 and EN 16351. NOTE 3 EAD 350865-00-1106 covers fire retardant products (coating) applied in situ.
