BS EN 417-2003 pdf download.Non-refillable metallic gas cartridges for liquefied petroleum gases, with or without a valve, for use with portable appliances — Construction, inspection, testing and marking.
Five containers shall be taken from every batch at random and subjected to the test described in clause C.2.
If any one of these containers does not satisfy the test, 10 additional containers shall be taken at random from the same batch and subjected to the test described in clause C.2.
If any one of these containers does not satisfy the test, the entire batch shall be rejected.
If the manufacturer of the cartridge Is also the filler then the pressure test shall be carried out only once, after filling.
7.3 Test performed by the valve manufacturer
The test shall be performed In accordance with 6.8 on a random sample of three valves taken from a batch constituting hourly production.
It any valve fails the test. 10 further samples taken from the same batch shall be tested. Any additional failure shall result in rejection of the batch.
Valves used for testing purposes shall be destroyed after the test.
7.4 Tests and Inspection performed by the filler
7.4.1 The cartridge gas charge shall be verified on one cartridge, taken at least every 10 mm. It the maximum charge specified in clause 5 is exceeded, the gas charge of each cartridge filled since the last sampling shall be checked to eliminate over-filled cartridges.
NOTE The cartridge gas charge may also be verified using the techniques of statistical process control. In order to minimize the quantity of overfilled cartridges, it Is recommended to verity the gas charge delivered by each filling head before filling commences. The weighing devices and manometers used in the filling of cartridges should be verified at least once per day.
7.4.2 The filler shall ensure that threaded centre boss valves comply with the requirements for mechanical strength (see 7.3) either by obtaining documented evidence from the manufacturer or by conducting the test in 6.8 on samples from each consignment of valves.
7.4.3 Each filled cartridge shall be immersed into a bath of hot water so that the pressure inside the container reaches at least 90 % of the pressure developed by the gas contained at 55 °C.
No leakage or visible deformation shall occur.
Defective cartridges shall be destroyed.
WARNING These tests are designed to sub)ect cartridges to relatively high pressures, and to detect gross over-filling. It is essential that adequate precautions should be taken to safeguard operators carrying out these tests.
7.4.4 In order to check that cartridges meet the requirements of 4.2.3, 4,2.4 and 4.2.5. the filler shall carry out the following tests on samples taken from either:
a) one uniform batch of cartridges, i.e. filled cartridges of the same design and construction filled in continuous production for half a day maximum: or
b) a batch constituting hourly production.
Five cartridges shall be taken from every batch at random, emptied of gas, and subjected to the test described in C.2.
If a single one of these cartridges does not satisfy the test, 10 additional cartridges shall be taken at random from the same batch, emptied of gas, and subjected to the test described in clause C.2.
If any one of these cartridges does not satisfy the test, the entire batch shall be rejected.
8 Marking
8.1 General
The markings on cartridges shall be durable, in characters which are easy to read (size, colour) and in the
language(s) of the country where they will be marketed.
8.2 Marking applicable to all cartridges
a) risk, safety phrases and hazard symbol(s) according to the appropriate current regulations;
NOTE Since the first edition of this European Standard, a number of Directives relating to the classification, marking and handling of cartridges covered by this standard have come into force, of which users of this standard should be aware.
b) TMprotect from direct sunlightTM
C) TMdo not expose to temperatures exceeding 50 °C°’;
d) name or mark of the company responsible for putting the product on the market;
e) commercial designation and type of the cartridge;
I) type of gas contained in letters not less than 3 mm high. (for example: butane or butane/propane mixture);
g) net weight of gas contained In grams;
h) indication (possibly coded) for identification of the filling batch:BS EN 417-2003 pdf download.
