18、e secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2002, and conflicting national standards shall be withdrawn at the latest by March 2002. This European
19、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 thermal insulating materials and products which derive from the Council Directive of 21 December 1
20、988 on the 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 prepared for products used to insulate building equipment
21、 and industrial installations, but it may also be applied to products used in other areas. No existing European Standard is superseded. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential req
22、uirements of EU Directive(s). According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxemb

38、lation product. The dimensions of the test specimens shall be measured including any surface skins, facings, and/or coatings on both the inner and the outer surfaces. NOTE For the measurement of circumference/outside diameter, inside diameter, and thickness the test specimen may be divided transvers
39、ely or longitudinally into several pieces; minimum dimension is 100 mm. Pipe insulation pieces (half sections or segments) which together form a complete pipe insulation layer, without visual deformation, shall be held in place by adhesive tape to facilitate measurement (see Figure 6). 2 half sectio

If the number is not specified, then at least three test specimens shall be used. NOTE In the absence of a product standard or an
41、y other European technical specification the number of test specimens may be agreed between parties. 6.3 Conditioning of test specimens The test specimens shall be stored for at least 6 h at (23 5) C. In case of dispute they shall be stored at (23 2) C and (50 5) % relative humidity for the time sta
42、ted in the relevant product standard.

In case of dispute it shall be carried out at (23 2) C and (5
43、0 5) % relative humidity. 7.2 Test procedure 7.2.1 General Determine the thickness, d, of the test specimen and its inside and outside diameter, Di and Do, from one of the following pairs of measurements: a) Outside circumference and inside diameter; b) Inside diameter and outside diameter; c) Insid
44、e diameter and thickness; d) Outside diameter and thickness; e) Outside circumference and thickness. Each set of measurements shall be performed at the same place on the pipe insulation. NOTE 1 The listed options are not equivalent. Only when thickness itself is measured, can an estimate of concentr
45、icity be obtained. NOTE 2 For pipe insulation with large inside diameter and small thickness attention should be paid to the required accuracy. Method c) or d) or e) should be used. Determine the length, l, deviation from squareness, v, and deviation from linearity, L, in accordance with 7.2.3, 7.2.
46、4 and 7.2.5. NOTE 3 Determination of deviation from squareness and deviation from linearity are not relevant for all materials and/or applications. 7.2.2 Circumference - outside diameter, inside diameter, wall thickness The appropriate apparatus, described in clause 5, shall be used for the measurem
47、ents below. During the measurement any longitudinal joints shall be kept close together. The pipe insulation shall not be visibly deformed due to the measuring process. Measure pipe insulation, with a length smaller than or equal to 600 mm, at two locations, either at the ends or 100 mm from each en
48、d. Measure pipe insulation, with a length larger than 600 mm, as above with one extra measurement for each additional 400 mm in length evenly distributed along the length, with a maximum of 5 measurements. NOTE The pipe insulation may be cut into smaller pieces at appropriate locations to facilitate
49、 measurement. The reading accuracy of the measurements shall correspond to the accuracy of the apparatus. 7.2.2.1 Circumference - outside diameter Measure the circumference, C, of the test specimen using a metal tape. Measure the outside diameter, Do, using either a metal tape or a caliper. Each measurement shall consist of two readings at right angles to the longitudinal axis of the test specimen at the selected locations. The readings of the outside diameter shall also be made at right angles to each other. Licens
