worldwide federation of national standards bodies (IS0 member bodies) The work of preparing International Standards is normally carried out through IS0 technical committees Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee International organizations, governmental and nongovernmental, in liaison with ISO, also take part in the work IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization Draft International Standards adopted by the technical committees are circulated to the member bodies for voting Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote International Standard IS0 61 82-4 was prepared by Technical Committee ISO/TC 21 , Equipment for fire protection and fire fighting, Sub-Committee SC 5, Fixed fire extinguishing systems IS0 61 82 consists of the

elastomer sealing element, other than gaskets, shall have the following properties when tested in accordance with 6.3.3 and the appropriate clauses of IS0 37: a) maximum set of mm when 25 mm tong marks are stretched to 75 mm, held for min, and measured after release; and b) either: minimum tensile strength 00 bar (1 MPa) ) and minimum ultimate elongation 300 % (25 mm to 00 mm), or 2) minimum tensile strength 50 bar (1 MPa) and minimum ultimate elongation 200 % (25 mm to 75 mm), and after exposure to oxygen for 96h at (70 -t 1,5) “C and 20 bar (2,0 MPa), c) the tensile strength and

or seat seal) shall be capable of being flexed without cracking or breaking and shall have a change in volumetric expansion not greater than 20 % when tested in accordance with 6.3.3 4.6 Non-metallic components (excluding gaskets and seals) 4.6.1 After ageing of its non-metallic parts as described in 6.3.1 and 6.3.2, a quick-opening device shall meet the requirements of 4.9 when tested in accordance with 6.5 and 6.6 Separate samples shall be used when testing in accordance with 6.3.1 and 6.3.2 Clearances shall be provided between and between stationary and moving corrosion or deposits

and, when tested in accordance with 6.7, debris shall not pass through any antiflooding device, if provided 4.9 Gauge connection A connection shall be provided to the upper chamber (holding chamber) of a quick-opening device for a suitable pressure gauge which will facilitate the detection of a clogged pressure-equalizing orifice 4.1 Operation A quick-opening device shall operate a specific dry pipe valve when the rate of system air pressure drop exceeds a specific rate as a result of the operation of one or more sprinklers, at all water supply pressures from ,4 bar to the maximum working pressure, therefore hastening the operating time of the dry pipe valve as verified by testing in accordance with 6.6 4.1 Maintainability A quick-opening device (and its associated antiflooding component, if provided) shall be designed to permit cleaning and maintenance without the use of special tools which shall be demonstrated by testing in accordance with 6.7 4.1 Equilibrium time It shall be established that the device does not exceed the criteria specified in 6.8 Production testing and quality control It shall be the responsibility of the manufacturer to implement a quality control programme to ensure that his production continuously meets the requirements of this part of IS0 61 82 in the same manner as the originally tested samples Every quick-opening device manufactured shall pass an aerostatic test at a minimum of 3,5 bar IS0 61 82-4:1 993(E) Every quick-opening device manufactured shall pass a test of operation which verifies correct function with the results recorded against each quick-opening device serial number Performance tests 6.1 General Representative samples of each quick-opening device shall be subjected to the tests described in these requirements 6.2 Metallic materials, components 6.3.2 Warm water ageing for non-metallic components (excluding gaskets and seals) See 4.6 Immerse four samples of each component in tap water at (87 f 2) “C for 80 days For parts which are occasionally exposed to water when the device operates, the test shall be conducted for a duration of only days Remove from the water and allow to cool to room temperature for examination If a material cannot withstand the temperature indicated without excessive softening, distortion or deterioration, carry out a water ageing test at a lower temperature (but not less than 70 “C) for a longer period of time Calculate the duration of exposure D, in days, from: D = 74 857 emovosg3r See 4.5.2 where t is the test temperature, in degrees Celsius NOTE See note Examine the component for cracking and warping, creep or other signs of deterioration which may preclude the proper operation of the device 6.3 Non-metallic components 6.3.3 Elastomeric sealing element tests 6.3.3.1 Reinforced elastomeric sealing element test See 4.5.7 Subject samples of a spring and a diaphragm employed in a quick-opening device to 000 and 000 cycles respectively of normal operation The tests shall be conducted at a rate not exceeding cycles per 6.3.1 Air-oven ageing for non-metallic components (excluding gaskets and seals) See 4.6 Age four samples of each component in an air oven at (1 20 f 2) “C for 80 days Support the components so that they not touch each other or the sides of the oven Remove the samples from the oven and allow to cool in air at (23 f 2) “C and relative humidity (50 f 5) % for not less than 24 h before carrying out any test, measurement or examination If a material cannot withstand the temperature indicated without excessive softening, distortion or deterioration, carry out an air-oven ageing test at a lower temperature (but not less than 70 “C) for a longer period of time Calculate the duration of exposure D, in days, from D= 737 000 eso*o6g3 where t is the test temperature, in degrees Celsius NOTE This equation is based on the “C rule, i.e for every “C rise, the rate of a chemical reaction is approximately doubled When applied to plastic ageing, it is assumed that the life at a temperature, t, in degrees Celsius, is half the life at (t- 0) in degrees Celsius Examine the component for cracking and warping, creep or other signs of deterioration which can preclude the proper operation of the device Measure the volume of reinforced elastomer sealing ‘elements and identify each sample Expose six samples to an atmosphere of oxygen at a pressure of 20 bar for 96 h at 70 “C Submerge the remaining six samples in boiling distilled water for 70 h; remove the samples and allow to cool to room temperature Measure the volume of each sample before bending each through an arc of 80” three times 6.3.3.2 Non-reinforced elastomeric sealing element test See 4.5.6 Prepare test specimens in accordance with IS0 37 Use four to satisfy the test requirements in either 4.5.6 b) ) or 4.5.6 b) 2) and four to satisfy each of the test requirements in 4.5.6 a), 4.5.6 c) and 4.5.6 d) 6.4 Pneumatic static pressure The
