16、 is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supports a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on t
17、he approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements. This European Standard has been drafted for applications in building, but it may also be used in
18、other areas where it is relevant.

BS EN 1609:2013EN 1609:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedures for determining the short-term water absorption of test specimens by partial immersion. It
31、is applicable to thermal insulating products. NOTE It is intended to simulate the water absorption caused by a 24 h raining period during construction work. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
32、application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

33、, Accuracy (trueness and precision) of measurement methods and results Part 2: Basic method for the determination of repeatability and reproducibility of a standard measurement method 3 Terms and definitions This European Standard contains no terms and definitions. 4 Principle A test specimen is pla
34、ced with its lower part in water, for a period of 24 h, and its change in mass is measured. The excess water adhering to the surface but not absorbed by the test specimen is removed by drainage (method A) or taken into account by deduction of the initial water uptake (method B). 5 Apparatus 5.1 Bala
35、nce, capable of determining the mass of a specimen to an accuracy of 0,1 g. 5.2 Water tank, with a device for keeping the water level constant to within 2 mm, and a device to keep the test specimen in position. The device to keep the test specimen in position shall not cover more than 15 % of the cr
36、oss-sectional area of the test specimen, which is exposed to water. An example is shown in Figure 1. 5.3 Tap water, adjusted to a temperature of (23 5) C. In case of dispute, deionised water shall be used. 5.4 Equipment for drainage. Examples are shown in Figures 2a) and 2b). 6 Test specimens 6.1 Di
37、mensions of test specimens The thickness of test specimens shall be the original product thickness. The test specimens shall be prisms of square cross section having a side length of (200 1) mm. BS EN 1609:2013EN 1609:2013 (E) 6 6.2 Number of test specimens The number of test specimens shall be as s
38、pecified in the relevant product standard. If the number is not specified, then at least four test specimens shall be used. In the absence of a product standard or any other European Technical Specification, the number of test specimens may be agreed between parties. 6.3 Preparation of test specimen
39、s The test specimens shall be cut so that they do not include product edges. The test specimens shall be prepared by methods that do not change the original structure of the product. Any skins, facings and/or coatings shall be retained. Special methods of preparation, when needed, are given in the r
40、elevant product standard or any other European Technical Specification. 6.4 Conditioning of test specimens The test specimens shall be conditioned for at least 6 h at (23 5) C. In case of dispute, they shall be conditioned at (23 2) C and (50 5) % relative humidity for the time stated in the relevan

In case of dispute, it shall be carried out at (23 2) C and (50 5) % relative humidity. 7.2 Test procedure 7.2.1 General The choice of the method (A or B) shall be as specified in the relevant product stand
42、ard. In the absence of a product standard or any other European Technical Specification, the method may be agreed between parties. The dimensions of the test specimens shall be measured in accordance with EN 12085. 7.2.2 Method A (drainage) Weigh the test specimen to the nearest 0,1 g to determine i
43、ts initial mass, m0. Testing shall be carried out with half the number of specimens with one larger face up and the other half with the same larger face down. Place the test specimen in the empty water tank and apply a sufficient load to keep it partially immersed when water is added. Carefully add
44、the water to the tank until the bottom face of the test specimen is (10 2) mm below the surface of the water (see example in Figure 1). Ensure that the water level remains constant during the test. BS EN 1609:2013EN 1609:2013 (E) 7 After 24 h 30 min, remove the test specimen; drain it for (10 0,5) m

Place the test specimen in the water tank in such position that it is partially immersed in water with its bottom face (10 2) mm below the water level. Remove the test specimen after 10 s holding it horizontally and place it,
48、within 5 s, in a plastic tray of known mass. Weigh this tray with the test specimen to determine the test specimen mass including the initial water uptake, m1.

After 24 h 30 min remove the test specimen, holding it horizontally, and place it, within 5 s, in the plastic tray of known mass to determine its mass, m24. Method B is only applicable if the initial water uptake is less than or equal to 0,5 kg/m2, where this is calcula
