12、Wa rme This European Standard was approved by CEN on 30 October 1997. CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographi
13、cal references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN
14、member into its own language and notified to the Central Secretariat has the same status as the official versions. CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, P

This European Standard shall be given the status of a na
16、tional standard, either by publication of an identical text or by endorsement, at the latest by May 1998, and conflicting national standards shall be withdrawn at the latest by May 1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countrie
17、s are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. This European Standard consists of the following parts:
18、 Part 1: Heat ageing Part 2: Photochemical ageing Part 3: Ageing in a reactive environment Consideration is being given to preparing further parts, to cover such processes as biochemical ageing. NOTE Persons using this standard should be familiar with normal laboratory practice. This standard does n
19、ot purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.Page 3 EN 12280-1:1997 BSI 1998 Introduction Ageing refers to
20、all “slow and irreversible” changes in the properties of a material resulting from its own instability, or from the effects of the environment. This alteration may affect the chemical structure of the polymers or additives, the composition of the material, or its physical condition. NOTE Combustion
21、is not considered to be an ageing process, as the deterioration happens very rapidly. Accelerated ageing methods are used as it is practically impossible to obtain experimental results under normal conditions of utilization. These methods involve simulations which reproduce the normal conditions of
22、utilization as closely as possible, but where the parameters are set so that ageing occurs more rapidly. This standard deals solely with accelerated ageing methods. 1 Scope This standard specifies three test procedures to assess the effect of heat ageing on the relevant physical properties of coated
23、 fabrics. 2 Normative references This European standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to
24、 or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. EN ISO 2231, Rubber- or plastics-coated fabrics Standard atmospheres for conditioning an
