DIN EN 13238:2010-06 EN 13238:2010 (E) 4 Introduction The Construction Products Directive requires products to be tested in their end use condition which, for the purpose of substrates, could lead to an economically unrealistic large variety of tests to be carried ou
20、t. This large spectrum has been reduced to a practical number of standard substrates that enables the majority of end use conditions to be represented. Rules for the selection of such substrates are given in this European Standard. This European Standard is intended for use in conjunction with Europ
21、ean Standards covering the reaction to fire test methods for the relevant construction products. DIN EN 13238:2010-06 EN 13238:2010 (E) 5 1 Scope This European Standard describes the conditioning procedures for test specimens which will be tested according to the European standards for reaction to f
22、ire. The rules for the selection of substrates for construction products when carrying out reaction to fire tests are also detailed in this European Standard. This European Standard does not contain requirements for the pre-drying of test specimens for the non-combustibility test according EN ISO 11
23、82; methods of cleaning (e.g. washing) and other methods for the assessment of durability aspects, which are dealt with in the relevant product standards. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、ral wool with uniformly dispersed binder or polymers 3.2 product material, element or component about which information is required 3.3 substrate product which is used immediately beneath the product about which information is required NOTE For a flooring, it is the floor on which the flooring is mo
31、unted or the material which represents this floor. 3.4 standard substrate product which is representative of the substrate used in end use applications 3.5 test specimen piece of the product which is to be tested together with or without any substrate or treatment NOTE The test specimen may include
32、an air gap. 3.6 conditioning exposure to a controlled atmosphere 4 Conditioning procedures 4.1 General Test specimens used by the laboratory to conduct tests according to EN ISO 1182, EN ISO 1716, EN ISO 9239-1, EN ISO 11925-2, EN 13823 and EN 14390 shall be conditioned at a temperature of (23 2) C
33、and a relative humidity of (50 5) %. NOTE This corresponds to the recommended atmosphere and normal tolerances given in ISO 554. Test specimens shall be arranged within the conditioning environment in such a way that air can circulate around each individual test specimen. Test specimens shall be con
34、ditioned either until constant mass is achieved (see 4.2) or for a fixed period (see 4.3). 4.2 Conditioning to constant mass Before testing, the test specimens shall be conditioned in the atmosphere specified in 4.1 for a minimum period of 48 h, until constant mass is achieved. Constant mass is cons
35、idered to be achieved when two successive weighing operations, carried out at an DIN EN 13238:2010-06 EN 13238:2010 (E) 7 interval of 24 h, do not differ by more than 0,1 % of the mass of the specimen or 0,1 g, whichever is the greater. A number of weighing devices may be necessary. At least one wei
36、ghing device shall have an accuracy of at least 0,1 g. 4.3 Conditioning for a fixed period Before starting conditioning for a fixed period, the test specimens shall be properly cured in accordance with manufacturers instructions and shall not contain excess water. The content of excess water shall b
37、e measured and shall be below 40 % before the test specimens are placed in the conditioning environment. Before testing the test specimens shall be conditioned in the atmosphere specified in 4.1 for the following minimum periods:. a) Minimum conditioning period of eight weeks: 1) fire retardant trea
38、ted wood and fire retardant treated wood based products; 2) cement based products; b) Minimum conditioning period of four weeks: 1) not fire retardant treated wood and not fire retardant treated wood based products; 2) calcium silicate products; 3) gypsum and gypsum based products; 4) all other prod
39、ucts containing hygroscopic materials; c) Minimum conditioning period of two weeks: all other products. 5 General rules for selection of substrates 5.1 General The substrates used by the laboratory to conduct tests according to EN ISO 9239-1, EN ISO 11925-2, EN 13823 and EN 14390, shall be evaluated
40、 when appropriate to determine their reaction to fire test performance and thus compliance with this standard. One indicative test shall be conducted on each batch of substrates. 5.2 Standard substrates for floorings 5.2.1 Test results using a standard substrate complying with the requirements of 5.
41、2.2 or 5.2.3 are applicable if the density of the end use substrate is at least 75 % of the nominal value of the density of that standard substrate. 5.2.2 End use substrates of classes A1 and A2-s1,d0 are represented by fibre cement board (in accordance with ISO 390) with thickness (8 2) mm, with de
42、nsity (1 800 200) kg/m3and with classification A2fl-s1, when insofar as for the EN ISO 9239-1 test the fibre cement board is tested as flooring but without a substrate. 5.2.3 End use substrates of wood and of classes A1 and A2-s1,d0 are represented by not fire retardant treated particleboard (in acc
43、ordance with EN 312) with thickness (20 2) mm, with density (680 50) kg/m3and with classification Cfl-s1 when tested (according to EN ISO 9239-1) as flooring but without a substrate. DIN EN 13238:2010-06 EN 13238:2010 (E) 8 5.2.4 When the end use substrates are not of wood and not of class A1 and no
44、t of class A2-s1,d0, the flooringshall be tested in end use condition. 5.2.5 The method of attachment (e.g. adhesive) of floorings shall be representative of end use application (see NOTE). The method of attachment in end use practice shall be reproduced in the preparation of the test specimens, i.e
45、. end use adhesive and end use quantities, etc. If the order in which the attachments are conducted is known, this shall also be reproduced in the test specimens, e.g. if in end use practice the adhesive is applied to the substrate and not to the flooring, then it shall be applied to the substrate d
46、uring the test specimen preparation. The same or greater time for curing and drying as used in end use practice shall also be allowed. If in practice different types of adhesive are used, test specimens with each of the different adhesives shall be prepared. NOTE Some floorings may also be tested wi
47、thout attachment (e.g. adhesive). 5.3 Standard substrates for construction products excluding floorings 5.3.1 A list of standard substrates is given in Table 1. 5.3.2 The choice of the substrate for the test specimens shall be made in view of the field of application of test results, taking into acc
48、ount the end use substrate and the following rules which apply together: 5.3.2.1 Each standard substrate represents end use substrates which have a density of at least 75 % of the nominal value of the density of that standard substrate. 5.3.2.2 Standard substrates of classes A1 and A2-s1,d0 represen
49、t end use substrates of classes A1 and A2-s1,d0 only. 5.3.2.3 The standard particleboard substrate and the standard plywood substrate represents end use wood based substrates and also any end use substrate of classes A1 and A2-s1,d0. 5.3.2.4 The standard gypsum plasterboard substrate is representative of end use gypsum plasterboard substrates and also any end use substrate of classes A1 and A2-s1,d0. The standard calcium silicate board substrate is not rep
