This document specifies a method for the determination of the preventive action of a wood preservative against the Reticulitermes species of European termites1 when the preservative is applied as a surface treatment to wood.
This method is applicable to:
— water-insoluble chemicals which are being studied as active ingredients;
— organic formulations, as supplied or as prepared in the laboratory by dilution of concentrates;
— organic water-dispersible formulations as supplied or as prepared in the laboratory by dilution of concentrates; and
— water-soluble materials, for example salts.
NOTE This method can be used in conjunction with an ageing procedure, for example EN 73 or EN 84.

This document describes a laboratory method for obtaining water samples from preservative treated wood exposed out of ground contact (wood held in the storage yard after treatment and which has been in conditions designed to simulate outdoor, out of ground contact situations), at increasing time intervals after exposure.

This document specifies the requirements for the design, manufacture and testing of cylinders, tubes and other pressure vessels of steel, stainless steel, aluminium alloys or of non-metallic construction material. These are intended for the stationary storage of gaseous hydrogen of up to a maximum water capacity of 10 000 l and a maximum allowable working pressure not exceeding 1 100 bar, of seamless metallic construction (Type 1) or of composite construction (Types 2, 3 and 4), hereafter referred to as pressure vessels. NOTE Additional requirements with regard to assemblies (manifolded cylinders and tubes and other pressure vessels) are not covered by this document. This document is not applicable to Type 2 and 3 vessels with welded liners. This document is not applicable to pressure vessels used for solid, liquid hydrogen or hybrid cryogenic-high pressure hydrogen storage applications. This document is not applicable to external piping which can be designed according to recognized standards.
