Amendments The following amendments have been made to the

10、 May 1981 edition. a) Additional requirements are specified for material classes A2 and B1. b) Smoke generation tests and toxicity tests are now included. c) The fire test using the Brandschacht apparatus is no longer included as it is now specified in DIN 41 02-1 6. Previous editions DIN 41 02-1 :

11、1977-09, 1981 -05. Dimensions in mm 1 Scope 1 .I This standard defines fire behaviour classes for building materials and specifies requirements and test methods for each class. It applies to sheet materials (including plates and slabs), composite materials, material assemblies, coverings, insulation

12、, coatings, pipes and fittings, decorative materials, curtains and other mate- rials suspended from ceilings, fire retardants, and intumescent coatings, whether or not these materials are designated as construction products (Bauprodukte) in the German Lander building regulations (cf. Explana- tory n

13、otes). 1.2 The classification specified in this standard serves to assess the fire behaviour of materials alone or in combination. Fire behaviour not only depends on the nature of the material, but also on its shape, surface characteristics, density, processing, and its combination with other materi

14、als, including any bonding agents or fasteners used. These factors are to be taken into account when preparing tests, selecting specimens, evalu- ating test results and marking the materials. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other publ

Materials wh

26、ich are designated as building products in the German Lander building regulations and which meet the general requirements of this standard for the relevant class still require additional proof I) when - the results of testing as in this standard are not alone sufficient for classification (cf. subcl

27、auses 5.1.2.1, 5.2.2.1 and 6.1.2.1), or - additional testing using other methods is required for classification. 4.2 Materials not requiring testing The building materials covered by DIN 41 02-4 shall be classed as specified therein without further testing. 5 Class A building materials 5.1 Class AI

28、materials 5.1.1 General requirements The test specified in subclause 5.1.3 provides a fire model describing the growth and full development phases of a fire. During these phases, class Al materials shall not release any ignitable gases or any considerable amount of heat. 5.1.2 Criteria for classific

29、ation 5.1.2.1 - pass the test specified in subclause 5.1.3 and - meet the requirements for class A2 materials (testing is not necessary here if it is evident beyond any doubt that these requirements are fulfilled). Materials may be classed as Al materials if they I) According to German building regu

30、lations, such materials either require general approval by the building inspectorate in the form of an agrment, or their suitability is to be verified on a case-by-case basis.

31、-05 The tests specified in this standard are not sufficient for assessing materials which are to meet additional requirements regarding the release of toxic gases; additional testing is required in this case.2) 5.1.2.2 The test specified in subclause 5.1.3 shall be deemed passed if - no flaming occu

32、rs (cf. subclause 5.1.4); - none of the specimens releases enough heat to cause the temperature in the furnace to rise by more than 50 “C above the initial temperature. 5.1.3 Furnace test 5.1.3.1 Five 40 mm x 40 mm x 50 mm specimens shall be tested (see figure 2 for tolerances). The specimens shall

33、be representative of the material. Specimens of materials delivered with a thickness less than 40 mm shall consist of several layers; in this case, each layer shall be cut to a length of 40 mm and a height of 50 mm, and thinned down, if necessary, so that the total thickness is 40 mm. The thickness

34、of compressible materials shall be that obtained under a load of 0,l kN/m2 per unit area. For materials containing varying quantities of combustible components (e.g. binders), the component with the highest combustibility shall be tested. For components with a lower combustibility, it is sufficient

35、to determine their quantity only (e.g. by checking ignition loss). Number and size of specimens 5.1.3.2 Coated materials Coatings applied at the works are to be tested along with the coated material. If both the material and its coating are to meet the requirements for class Al, the coating thicknes

Then, tie the specimen with a temperature-resistant wire (e.g. of NiCr) having a 0,2 mm diameter, binding the specimen in the middle so that the layers are held firm

39、ly together. Cut surfaces are not to face outwards (cf. figure 2). Place tied specimens in a wire holder weighing (5 I 0,5) g; this will help keep the specimen in the same position. Place specimens which may disintegrate during testing or which are of loose material in a basket of stainless steel wi

Specimens which could run out of the wire basket during testing are to be placed in a container of nickel sheet that is 0.2 mm thick. 5.1.3.4 Apparatus and procedure Apparatus Testing is to be carried out in an ele

44、 Normung E.V.- EnglishLicensed by Information Handling ServicesPage 6 DIN 41 02-1 : 1998-05 To measure the temperature inside the furnace, insert a thermocouple reaching down to the centre of the heating tube (cf. figure 1) at a distance of (1 O I0,5) mm from the tube wall. The thermocouple shall be

45、 made of a 0,5 mm thick wire with an open junction; sheathed thermocouples with an appropriate response charac- teristic may also be used. The temperature indicator shall have a limit of error no greater than 5 “C. A pilot flame of propane gas as in DIN 51 622 is to be located (20 Il) mm above the c

46、entre of the heating tubes top opening. To observe the specimen during testing, place a slanted mirror above the furnace. Procedure Pre-heat the furnace to (750 I 1 O) “C; this temperature is to remain constant to within I 1 “C without needing readjustment for at least ten minutes before testing. Th

47、e energy input to the heating element is to remain constant throughout the test. Suspend the specimen in the heating tube so that its centre is level with the junction of the thermocouple. The original specimen surface, or - in the case of asymmetrical specimens -the least favourable surface in term

48、s of fire behaviour is to face the thermocouple, which shall be located midway across this surfaces width (cf. figure 2). Multi-layered specimens are to be suspended as shown in figure 2. When suspending the specimen, do not open the furnace cover for more than five seconds. The test period begins w

49、hen the bottom edge of the specimen passes the top edge of the heating tube. Leave the specimen in the furnace until the maximum furnace temperature has been reached, and for at least 15 minutes. If the initial furnace temperature has still not risen after 30 minutes, only one specimen needs to be tested to the point where the maximum temperature is reached (but for no longer than 90 minutes), provided the other specimens behave in a similar manner during the first 30 minutes. If the pilot flame is extinguished by gases released by the specimen, an immediate attem
