NOTE 1: UN pressure receptacles and service equipment constructed according to standards
applicable at the date of manufacture may continue in use subject to the periodic inspection
provisions of ADR.
NOTE2: When EN ISO versions of the following ISO standards are available, they may be used
to fulfil the requirements of 6.2.2.1, 6.2.2.2, 6.2.2.3 and 6.2.2.4.

Design, construction and initial inspection and test

The following standards apply for the design, construction, and initial inspection and test of
