24、oses Method of test for flammability1 ScopeThis International Standard specifies a method for assessing the flammability of hoses, except for hoses intended for use with petroleum fuels for combustion engines. The method is restricted to hoses of sizes up to and including nominal bore of 50 mm.NOTE

25、1 The user is referred to the applicable hose standard for flame/afterglow requirements.NOTE 2 The method of test for flammability of hoses for use with petroleum fuels is given in ISO 137741.2 Normative referencesThe following referenced documents are indispensable for the application of this docum

26、ent. For dated references, only the edition cited applies.

28、re important to note that the results obtained can only be indicative and do not allow the prediction of behaviour in a fire. It is above all a screening or quality control test and has been used for many years to assess the suitability of hoses for underground use in particular.Attention is drawn t

29、o the need for ensuring that the test specified in this International Standard is carried out under suitable environmental conditions and that personnel are adequately protected against risk of fire, and inhalation of smoke and/or toxic products of combustion.4 Apparatus4.1 Draught-free cabinet, wit

30、h, a hole at the top for the escape of fumes, a hand-hole and flap for handling the burner and a sliding door with a viewing panel of toughened soda glass or any suitable transparent material. The arrangement and approximate dimensions of the cabinet are shown in Figure 1.Alternatively, the test cou

31、ld be done under a laboratory fume chamber.4.2 Gas burner (Bunsen type), having a burner tube of inside diameter of (10 0,5) mm, as illustrated in Figure 2.4.3 Commercial propane gas, as specified in ISO 9162.4.4 Stand, for supporting the test piece in a horizontal position above the burner (see Fig

33、e, as specified in ISO 8056-1 or its equivalent.5 Test pieceThe test piece shall be a 300 mm long sample of hose. Six test pieces shall be tested.6 ConditioningNo test shall be carried out within 24 h of manufacture of the hose. Test pieces shall be conditioned at standard temperature and humidity (

34、see ISO 23529) for at least 3 h before testing. This may be part of the 24 h period after manufacture.7 Procedure7.1 Place the test piece in the test rig (see Figure 3), and then place the test rig in the cabinet (see Figure 1).7.2 Light the burner and preheat it for 2 min. Adjust the air and gas fl

35、ow to give a total flame height of between 150 mm to 180 mm, with an inner flame length of approximately 50 mm.Position the thermocouple in the hottest part of the flame (i.e. just above the inner flame cone as shown in Figure 2) and check that the temperature is 1 000 C 20 C.If necessary, adjust th

36、e burner flame so that the temperature recorded is 1 000 C 20 C.Other temperatures can be used when specified in the hose product standard.7.3 Place the burner at 45 (see Figure 3) at the midpoint position of the test piece with the top of the burner tube approximately 50 mm below the bottom edge of

37、 the test piece so that the flame produces the set temperature of 1 000 C 20 C at this point.7.4 After 60 s + 1 s, remove the burner from the test rig, record the duration of flame persistence and the afterglow time.7.5 Test the further five test pieces as described in 7.1 to 7.4.NOTE It may be nece

38、ssary to shade the area to observe the afterglow.8 Expression of results8.1 Record for each test pieces tested the duration of the persistence of flame and the afterglow time.8.2 Calculate and record the mean duration of flame and the afterglow time and if any the presence of burning droplets.8.3 No

41、a means of assessing the potential fire hazard of the hose in use.”b) a statement that the test was carried out in accordance with ISO 8030:2014;c) the nominal bore of the hose;d) the hose type and standard, the date of manufacture and batch number or reference, if known;e) the method of manufacture
