Annex H (informative) Acceptance test
Acceptance tests and verifications are carried out on the finished SSD by the manufacturer in the presence of the purchaser’s inspector before shipping, if specified in the order specification.
The tests are:
dimensional check and visual inspection in accordance with 7.1;
material check in accordance with 7.2;
external tightness test in accordance with 7.7;
internal sealing in accordance with 7.8;
set value of the trip pressure in accordance with 7.9.2 at ambient temperature.
Unless otherwise specified, the number of SSDs selected for an acceptance test should be as follows:
2 SSDs for batches of 2 to 4 pieces;
3 SSDs for batches of 5 to 8 pieces;
4 SSDs for a batches of 9 to 20 pieces;
5 SSDs for batches of 21 to 30 pieces;
6 SSDs for batches of 31 to 60 pieces;

Annex K (informative)
! Suitability of safety shut-off device for damp operating conditions
K.1 Test procedure, requirement and acceptance criteria
This type test should be applied to SSDs actuated by a levers system not immersed in the flowing gas.
It should be carried out on, at least, one size of SSD, which should be representative of all sizes of the relevant series of SSDs actuated by a levers system not immersed in the flowing gas.
The SSD shall be equipped with:
the over-pressure setting element for the lowest set range and set at mid-point pdso. The setting shall not be adjusted throughout the test and
vent lines, if any, as specified by the manufacturer.
The SSD is installed inside an appropriate chamber:
at most critical position specified by manufacturer,
with the inlet and outlet end connections sealed,
with only the controller under a pressure. Special provisions shall be adopted for SSDs that are internally impulsed from the inlet or outlet side,
latched at open position
and subjected 100 cycles of temperature and humidity as follows.
A cycle shall take a minimum period of 5 h from (60 ± 2) °C at minimum of 90 % relative humidity to (5 ±2) °C at a minimum of 90 % relative humidity to (60 ±2) °C at minimum of 90 % relative humidity.
After completion of 100 cycles, the SSD shall be brought to ambient temperature and subjected to the following test:
a) ensure that the body is at atmospheric pressure;
b) with the SSD in the open position, starting from approximately 80 % of the selected trip pressure, increase the monitored pressure at a pressure change rate not greater than 1,5 % of the selected trip pressure per second until closure of the SSD occurs.
The test requirements are met if the value of the trip pressure in b) is within:

Annex ZA (informative)
Relationship between this European Standard and the Essential Requirements of EU Directive 97/23/EC
This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the New Approach Directive 97/23/EC (PED).
Once this standard is cited in the Official Journal of the European Communities under that Directive and has been implemented as a national standard in a least one Member State, compliance with the clauses of this standard given in Table ZA.1 confers, within the limits of the scope of this standard, a presumption of conformity with the corresponding Essential Requirements of that Directive and associated EFTA regulations.
