31、N ISO 2440:1999 + A1:2010 + A2:2014 (E) 5 WARNING Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish app

32、ropriate safety and health practices and to ensure compliance with any national regulatory conditions. 1 Scope This International Standard specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions

33、such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both openand closed-cell polyurethane foams, and closed-cell polyolefin foams. Condition

34、s for other materials will be added as required. The effect of the ageing procedures on any of the physical properties of the material may be examined, but those normally tested are either the elongation and tensile properties, or the compression or indentation hardness properties. These tests do no

35、t necessarily correlate either with service behaviour or with ageing by exposure to light. #If desired, the ageing conditions contained in this International Standard can be applied to composite structures containing any of the above types of cellular material. This can be helpful in the investigati

36、on of possible interactions between cellular materials and other substrates. Composite constructions can be in the form of complete finished products or representative small specimens cut there-from.$ 2 Normative references The following referenced documents are indispensable for the application of

37、this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. !ISO 23529, Rubber General procedures for preparing and conditioning test pieces for physical test methods“ 3 Apparatus 3.1 F

38、or heat ageing 3.1.1 Oven, with forced circulation, capable of maintaining the required temperature !to within 3 C“. NOTE It is recommended that a device be used to record the temperature, preferably continuously. 3.2 For humidity ageing 3.2.1 Ageing apparatus, of such a size that the total volume o

39、f the test pieces does not exceed 10 % of the free air space, and such that the test pieces are free of strain, freely exposed to the ageing atmosphere on all sides and not exposed to light. 3.2.2 Steam autoclave or similar vessel, capable of maintaining the required temperature !to within 3 C“ and

40、of withstanding absolute pressures up to 300 kPa. 3.2.3 Glass vessel, with a suitable closure, and a water-bath or drying oven for heating the vessel, capable of maintaining the required temperature !to within 3 C“. DIN EN ISO 2440:2015-02 EN ISO 2440:1999 + A1:2010 + A2:2014 (E) 6 3.3 For physical-

41、property measurements Use apparatus appropriate to the measurements of the physical property to be examined. 4 Test pieces 4.1 Number, size and shape The number of test pieces, and their size and shape, shall be appropriate to the property being examined. They shall be prepared, before ageing, to th

42、e dimensions used in the particular test. 4.2 Conditioning Material shall not be tested less than 72 h after manufacture, unless at either 16 h or 48 h after manufacture it can be demonstrated that the mean result does not differ by more than 10 % from those obtained after 72 h. Testing is permitted

43、 at either 16 h or 48 h if, at the specified time, the above criterion has been satisfied. Prior to the test, the test pieces shall be conditioned, undeflected and undistorted, for at least 16 h in one of the following atmospheres as given in !ISO 23529“: 23 C 2 C, (50 5) % relative humidity; 27 C 2

44、 C, (65 5) % relative humidity. This period can form the latter part of the period following manufacture. NOTE It is recommended that for reference purposes the test be performed 7 days or more after the cellular material has been manufactured. 5 Procedure 5.1 General After conditioning, the test of

45、 the required physical property shall be performed and the test pieces shall be brought rapidly to the ageing condition. If the test to be performed is destructive, for example the examination of tensile properties, it is recommended that the tests on both reference and aged material be performed at

46、 the same time, that is after the exposure of the latter to the ageing conditions. The ageing conditions shall be chosen from the following alternatives which should be appropriate to the material under test. It is recommended that materials differing in chemical composition should not be aged in th

47、e same enclosure. #If a finished product is being studied for interaction effects, ensure that the test enclosure contains only that finished product test specimen.$ 5.2 Dry heat ageing 5.2.1 Temperatures Polyolefin 70 C Latex 70 C or 100 C !Polyurethane 80 C, 125 C or 140 C“ DIN EN ISO 2440:2015-02

48、 EN ISO 2440:1999 + A1:2010 + A2:2014 (E) 7 NOTE The use of the non-standard temperature of 140 C is included for the following technical reason: the temperature of the ageing test should be as high as possible to enable results to be obtained in the minimum time, but above this critical temperature

49、 the changes which occur when polyurethane foam is tested are not those which are found in service, so that the ageing test will no longer discriminate between foams of different behaviour in service. 5.2.2 Duration of ageing Use 16 h, 22 h, 72 h, 96 h, 168 h, 240 h or some multiple of 168 h, with a tolerance 5 %, but not more than 4 h. 5.3 Humidity ageing 5.3.1 Humidity Use 100 % relative humidity or saturated steam. 5.3.2 Temperatures a
