3.2 hose tail part of the coupling that is inserted into the hose during assembly NOTE 1 to entry: On small couplings, a hose tail is called a hose spigot. [SOURCE: EN ISO 8330:2014, 2.2.20] 3.3 coupling connector fitting, usually made of metal, attached to the end of a hose to facilitate connection to equipment NOTE 1 to entry: A female coupling carries the internal fastening; a male coupling carries the external fastening.

NOTE The following materials fulfil this requirement — Brass according to — EN 12164; — EN 12165; — ISO 197-1; — ISO 197-3; — plated steel; — and stainless steel. 5.2 Length of assembly The length of the assembly shall be equal to the nominal length within a tolerance of ± 2 %. 5.3 Securing of couplings on hoses or tubing Both ends of hose or tubing shall be secured to the hose tails by means of clamps, crimps, or clips and shall conform to the ‘pull-off’ requirements specified in Annex C.3. NOTE Attention is drawn to national regulations relating to the use of fixing devices on hoses and tubing and users' obligations there under. 5.4 Design of couplings for use in assemblies The dimensions of the hose tail shall be compatible with the dimensions of the hose or tubing. The method of attachment of the hose tail shall be such that the hose or tubing assembly complies with the requirements of 6. Information related to the main types and dimensions of the couplings and coupling tails used are given in Annex B. The design of the coupling shall be such that the assembly can be secured at a minimum of one end without the necessity of turning the hose or tubing relative to its mating piece and without the use of additional fittings.
