4.1 General

Materials used in the construction of nozzles shall be chemically and dimensionally stable under known

service conditions. Materials likely to come into contact with fuels, both in liquid and vapour phases,

shall be resistant to attack by these fuels. Conformity shall be demonstrated by manufacturers'

declarations and by the tests detailed in Annex B.

The nozzle shall be explosion-protected and shall be Category 2, Group II, EPL Gb in accordance with

EN ISO 80079-36. Components fitted to the spout and within the vapour recovery path shall be

Category 1, Group II, EPL Ga in accordance with EN ISO 80079-36. The nozzle shall fulfil the

requirements for temperature class T3 and group IIA according to EN 60079-0 or EN ISO 80079-36. The

nozzle shall have a manually controlled operating device, which may incorporate an integral latch, to

control the liquid flow. Where a latch is provided, it shall be possible to disable the latching function.

The surfaces and mechanisms of the nozzle which, in normal operation, come into contact with the

operator shall be such that they present no risk of injury. Conformity to this requirement is

demonstrated by visual inspection of a nozzle.

Nozzles shall be classified as Type I or Type II according to the delivery characteristics given in Table 1.
