17、This European Standard 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 insulating materials and products which derive from the Council Directive of 21 Dece

18、mber 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (89/106/EEC) through the consideration of the essential requirements. This European Standard gives the reference method. Other methods may be used (e.g. for qualit

19、y control), provided a correlation has been established with this reference method; Annex B gives some examples of such methods. This European standard has been drafted for applications in building but it may also be used in other areas where it is relevant. This European test standard is one of the

34、cimen rests and a pressure plate resting freely on the top face of the test specimen. 5 Apparatus 5.1 Measuring device, comprising a dial gauge and a square pressure plate. An example of a suitable apparatus is given in Figure 1. 5.1.1 Dial gauge, capable of measuring to an accuracy of at least 0,5

35、mm1)and mounted on a rigid frame fastened to a flat rigid base plate which is at least as large as the test specimen. 5.1.2 Pressure plate, 200 mm square, which exerts a total pressure on the test specimen of either (50 1,5) Pa or (250 5) Pa (including the force exerted by the dial gauge). The press

36、ure shall be as given in the relevant product standard. Any test equipment which provides the same result with at least the same accuracy may be used. 1) If a higher accuracy is required, it is specified in the relevant product standard or agreed between parties.

In cases of dispute, they shall be stored at (23 2) C and (50 5) % relative humidity for the time specified in the relevant product standard. 6.4 Preparation of test specimens Any facings or coatings shall be retained. For compressed products, the pre
