This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorse
18、ment, at the latest by September 2013, and conflicting national standards shall be withdrawn at the latest by September 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for ide

The revision of this standard contains no major changes, only minor corrections and clarifications of an editorial nature. This European Standard is one of a series of standards which specify test methods for determining
20、 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 the approximation of laws, regulations and administrative provisions of the
21、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 buildings but may also be used in other areas where it is relevant. This European test standard is one of the fo

DIN EN 12087:2013-06 EN 12087:2013 (E) 5 1 Scope This European Standard specifies the equipment and procedures for determining the long-term water absorption of test specimens. It is applicable to thermal insulating products. This European Standard specifies two op
35、tions: Method 1 - partial immersion Method 2 - total immersion The long-term water absorption by partial immersion is intended to simulate the water absorption caused by long term water exposure. The long-term water absorption by total immersion is not directly related to the conditions on site, but
36、 has been recognised as a relevant condition of test for some products in some applications. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

39、s determined by measuring the change in mass of a test specimen, the lower part of which is in contact with water for a period of 28 days. The excess water adhering to the surface, not absorbed by the test specimen, is removed by drainage in method 1A or taken into account by deduction of the initia
40、l water uptake in method 1B. 4.2 Total immersion (method 2) The long term water absorption by total immersion is determined by measuring the change in mass of the test specimen, totally immersed in water, over a period of 28 days. The excess water adhering to the surface, not absorbed by the test sp
41、ecimen, is removed by drainage in method 2A or taken into account by deduction of the initial water uptake in method 2B. 5 Apparatus 5.1 Balance, which allows the determination of the mass of a test specimen to 0,1 g. 5.2 Water tank, with a device for keeping the water level constant to within 2 mm,
42、 and a device to keep the test specimen in the required position. DIN EN 12087:2013-06 EN 12087:2013 (E) 6 Examples of test devices are given in the Figures 1, 2 and 3. The device to keep the test specimen in position shall not cover more than 15 % of the cross section area of the test specimen, whi
43、ch is exposed to water. The device shall be such that the original form of the test specimen is maintained.
