This document applies to type D and type SD hose assemblies with hoses made of elastomers and bonded plastics for the transport of gaseous, vaporous, liquid or powdery substances in the pharmaceutical and the biotechnological industries. It specifies the classification, manufacturing and testing of as well as the materials, requirements and quality surveillance for hose assemblies. These hose assemblies are intended to be used with the relevant substances at temperatures in the range from −30 °C to +100 °C, depending on the medium, and at operating pressures from −0,9 bar (vacuum) to 10 bar (see Table 2 and Table 3). For hoses with a lining made of PTFE and derivatives, temperatures from −30 °C to +140 °C are permissible. Hose assemblies in accordance with this document are classified into four types, A - D, A - SD. B - D, B - SD.

This document specifies the minimum requirements for inspection at time of filling of battery-vehicles and multiple-element gas containers (MEGCs) for compressed and liquefied gases. The elements of battery vehicles and MEGCs covered by this document are: - seamless steel or seamless aluminium alloy cylinders or tubes, and - composite cylinders or tubes (hoop-wrapped or fully-wrapped) with a water capacity up to 3000 l. This document is not applicable to MEGCs using tanks as elements. This document is not applicable to the automotive components of a battery trailer. Unless noted by exception the use of the word "cylinders" in this document refers to both cylinders and tubes. NOTE Acetylene battery-vehicles are covered by EN 13720.

This document specifies the requirements for the design, manufacture, identification and testing of battery vehicles and multiple-element gas containers (MEGCs) containing cylinders, tubes, or bundles of cylinders. This document applies also to battery vehicles and MEGCs containing bundles of cylinders connected by a manifold which are dis-assembled from the battery vehicle and filled individually. It is applicable to battery vehicles and MEGCs containing compressed gas, liquefied gas, and mixtures thereof. It is also applicable to battery vehicles for dissolved acetylene. This document is not applicable to battery vehicles and MEGC for toxic gases with an LC50 value less than or equal to 200 ml/m3. This document does not apply to battery vehicles and MEGCs containing pressure drums or tanks. This document does not specify requirements for the vehicle chassis or motive unit. This document is primarily intended for industrial gases other than Liquefied Petroleum Gases (LPG).
