This European Standard shall be given the statu

17、s 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of an identical text or by endorsement, at the latest by March 2002, and conflicting national standards shall be withdrawn at the latest by March 2002.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 Standard is one of a series of standards which specify test methods for determining di

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 Mem

19、ber 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 and industrial installations, but it may also be applied to products used in other ar

40、 d, of the test specimen and its inside and outside diameter, 4 and Do, from one of the following pairs of measurements: a) Outside circumference and inside diameter; b) Inside diameter and outside diameter; c) Inside diameter and thickness; d) Outside diameter and thickness; e) Outside circumferenc

41、e 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 concentricity be obtained. NOTE 2 For pipe insulation with large inside diameter and small t

42、hickness attention should be paid to the required accuracy. Method c) or d) or e) should be used. Determine the length, I, deviation from squareness, v, and deviation from linearity, L, in accordance with 7.2.3, 7.2.4 and 7.2.5. NOTE 3 Determination of deviation from squareness and deviation from li

43、nearity 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 measurements below. During the measurement any longitudinal joints shall be kept close toget

44、her. 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 1 O0 mm from each end. Measure pipe insulation, with a length larger than 600 mm, as above with one ext

45、ra 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 measurement. The reading accuracy of the measurements shall correspond to the accu

46、racy 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

47、the test specimen at the selected locations. The readings of the outside diameter shall also be made at right angles to each other. 9 EN 13467:2001 (E) 7.2.2.2 Incide diameter Measure the inside diameter, Q, using either a metal tape or a caliper. Each measurement shall consist of two readings at ri

48、ght angles to the longitudinal axis of the test specimen at the selected locations. The readings of the inside diameter shall also be made at right angles to each other. Alternatively the inside diameter may be measured with a conical mandrel moved into position along the major axis of the pipe insu

49、lation. NOTE For inside diameter greater than 55 rnm the use of a conical mandrel may be impractical. 7.2.2.3 Thickness Measure the thickness, d, using either a metal tape, a caliper or a thickness gauge. Each measurement shall consist of four readings at right angles to each other at the selected locations. When a thickness gauge is used on a metal pipe (see 5.1.2) the pipe insulation shall be supported (see Figure 2). Before making measurements on the pipe insulation the thickness gauge shall be read with the measuring plate resting on the metal pipe. The pipe insul
