The work of preparing International Standards is normally carried out thr

11、ough ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabo

12、rates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standar

13、ds. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of thi

14、s document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 18098 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 1, Test and measurement methods.ISO 1

15、8098 includes the original EN 13470 prepared by Technical Committee CEN/TC 88, Thermal insulating materials and products.

32、ethods for determining dimensions and properties of thermal insulating materials and products. The original EN 13470 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, regulati

33、ons, and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through the consideration of the essential requirements.This International Standard has been prepared for products used to insulate building equipment and industrial installations, but it

34、 may also be applied to products used in other areas. ISO 2013 All rights reserved viiBS ISO 18098:2013BS ISO 18098:2013Thermal insulating products for building equipment and industrial installations Determination of the apparent density of preformed pipe insulation1 ScopeThis International Standard

35、 specifies the equipment and procedures for determining the apparent overall density and the apparent core density under reference conditions. It is applicable to full-size thermal insulating products and test specimens of preformed pipe insulation.2 Normative referencesThe following documents, in w

36、hole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.

39、as the quotient of the mass and the volume of the test specimen.5 Apparatus5.1 Balance, capable of determining the mass of a test specimen to an accuracy of 0,5 %.5.2 Equipment, for the determination of the dimensions of preformed pipe insulation (see 7.2).INTERNATIONAL STANDARD ISO 18098:2013(E) IS

40、O 2013 All rights reserved 1BS ISO 18098:2013ISO 18098:2013(E)6 Test specimens6.1 Dimensions of test specimensThe test specimens shall be full-size products or parts of them, or test specimens used for other tests.When the apparent overall density is being determined using test specimens cut from a

41、product with surface skins formed during production, the ratio of the area of the surface skin to the total volume shall be the same for the test specimen as for the product.The size of a test specimen should preferably be as large as possible, commensurate with the apparatus available and with the

42、shape of the original product. The size of the test specimens may also be specified in other test methods.6.2 Number of test specimensThe number of test specimens for full-size products shall be as specified in the relevant product standard. If test specimens from other tests are used, the number sh

43、all be as specified in the test method. If the number is not specified, then at least three test specimens shall be used.NOTE In the absence of a product standard or any other international technical specification, the number of test specimens may be agreed between parties.6.3 Preparation of test sp

44、ecimensThe test specimens shall be cut by methods that do not change the original structure of the product.The location from which the test specimens are taken shall be such that the density obtained is representative of the density of the product.For determining the apparent overall density, any fa

45、cings and/or coatings shall be removed from the product. For determining the apparent core density, any surface skins formed during production and any facings and/or coatings shall be removed from the product.When it is not possible to remove the facings and/or coatings without influencing the appar

46、ent density of the product, the mass of the facings and/or coatings shall be deducted by calculation.NOTE Special methods of preparation, when needed, are given in the relevant product standard.6.4 Conditioning of test specimensThe test specimens shall be conditioned at (23 2) C and (50 5) % relativ

47、e humidity (RH) until constant mass is achieved.The time for conditioning and the required accuracy of the constant mass measurements shall be given in the relevant product standard.NOTE 1 If it can be shown that temperature and humidity has negligible influence on the determination of the density,

48、then the conditioning can be carried out at (23 5) C.NOTE 2 The conditioning time can be shortened by pre-drying the test specimen in a ventilated drying chamber at a prescribed temperature. Appropriate procedures may be given in the relevant product standard.In tropical countries, different conditi

49、oning and testing conditions can be relevant. In this case, the conditions shall be (27 5) C and (65 5) % RH.2 ISO 2013 All rights reservedBS ISO 18098:2013ISO 18098:2013(E)7 Procedure7.1 Test conditionsThe test shall be carried out at (23 2) C and (50 5) % RH.NOTE If it can be shown that temperature and humidity has negligible influence on the determination of the density, the testing can be carried out at (23 5) C.In tropical countries, different conditioning and
