Test methods are specified for complete or parts of devices. If deviations from the test method given in this part

22、of ISO 16900 are necessary, these deviations will be specified in the relevant performance standard.The following definitions apply in understanding how to implement an ISO International Standard and other normative ISO deliverables (TS, PAS, IWA): “shall” indicates a requirement; “should” indicates

23、 a recommendation; “may” is used to indicate that something is permitted; “can” is used to indicate that something is possible, for example, that an organization or individual is able to do something.3.3.1 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a requirement as an “expressio

24、n in the content of a document conveying criteria to be fulfilled if compliance with the document is to be claimed and from which no deviation is permitted”.3.3.2 of the ISO/IEC Directives, Part 2 (sixth edition, 2011) defines a recommendation as an “expression in the content of a document conveying

25、 that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others or that a certain course of action is preferred, but not necessarily required, or that (in the negative form) a certain possibility or course of action is deprecated but not prohibit

Except for temperature limits, values

33、 which are not stated as maxima or minima shall be subjected to a tolerance of 5 %. Unless otherwise specified, the ambient temperature for testing shall be between 16 C and 32 C, (50 30) % RH and any temperature limits specified shall be subjected to an accuracy of 1 C.Where the assessment of the p

34、ass/fail criterion depends on a measurement, an uncertainty of measurement as described in Annex A will be given.6 Test methods6.1 Resistance to hot particles (embers/sparks/ash)6.1.1 PrincipleTo determine the effect of the exposure, the test consists of exposing those parts specified in the perform

35、ance standards to a heated wire.6.1.2 ApparatusThe test rig consists of a loop of Nichrome wire as shown in Figure 1.The Nichrome wire shall be connected to a power supply. A wire temperature of (500 +500) C shall be maintained.6.1.3 ProcedureThe RPD shall be mounted on the manikin (e.g. RPD torso a

36、nd head form in accordance with ISO 16900-5) to simulate the correct wearing position.The RPD test locations chosen shall include each material and material interface that is exposed during use.The heated wire shall be placed on each test location for (3 +10) s.Carry out a visual inspection during t

37、he test in order to establish whether the test specimen ignites or melts through as specified in the RPD performance standard.Observe whether or not the specimen melts or ignites.6.1.4 Test reportThe test report shall include information regarding those parameters specified in Clause 4, together wit

39、incipleThe test consists of exposing the specimen specified in the performance standards to a flame of an array of six burners at (950 50) C for the required time exposure of 5 s.6.2.1.2 ApparatusThe test rig consists mainly of a propane cylinder with flow control device, flow meter, pressure gauge,

40、 flashback arrester, RPD head form size medium in accordance with ISO 16900-5, and six propane Teclu burners which are adjustable in height. Figures 2 and 3 show schematic diagrams of the apparatus and the top view of the arrangements of the burners. The purity of the propane shall be a minimum of 9

41、5 %.6.2.1.3 ProcedureMount the specimen on the RPD head form size medium or any suitable alternative such that the external parts have direct exposure to the flame. Before lighting the burners, position the specimen centrally above the array of burners and individually adjust the height of each burn

42、er such that the distance between the burner tip and specimen is 250 mm. Figure 2 shows the adjustment of the burner tips of one example of specimen.Determine the leakage of the test specimen for type T respiratory interfaces by applying 1 000 Pa negative pressure and measuring the pressure drop wit

43、hin one minute.For type L respiratory interfaces, the pressure in the respiratory interface prior to the flame exposure shall be measured when a positive pressure is applied by a flow of 1,5 l/min.With the specimen removed from above the burners, fully open the propane control valve on each of the b

44、urners. Initially, close the air control valve on each of the burners. Ignite the burners and adjust the propane cylinder output regulator to a pressure such that a flow meter in the main propane supply line indicates a total flow to all burners of (21 0,5) l/min propane.A mineral insulated thermoco

45、uple probe with a diameter of 1,5 mm shall be used to measure flame temperature. The temperature shall be measured at a point 250 mm above the upper tip of any burner in the centre of the flame. All burners shall give flame temperature within the tolerance required (950 50) C. The burners shall be a

46、djusted to their correct position (height) before measuring any flame temperature.In order to achieve the correct temperature, it may be necessary to adjust the air control valve on each burner to an optimum and to shield the whole test rig from the effect of external air flows.
