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of an identical text or by endorsement, at the latest by February 2003, and conflicting national standards shall be withdrawn at the latest by February 2003. This
16、 European Standard EN 12280 “Rubber- or plastic-coated fabrics - Accelerated ageing tests“ consists of the following parts: Part 1: Heat ageing Part 2: Physical ageing: effect of light or weathering Part 3: Environmental ageing This Part includes one informative annex A. Consideration is being given
17、 to preparing further parts, to cover such processes as biochemical ageing. WARNING: Persons using this standard should be familiar with normal laboratory practice. This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the
18、user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgi
19、um, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. EN 12280-2:2002 (E) 4 Introduction Ageing refers to all “slow and irreversible“ changes in the properties of a
20、material resulting from its own instability, or from the effects of the environment. This alteration can affect the chemical structure of the polymers or additives, the composition of the material, or its physical properties. NOTECombustion is not considered to be an ageing process, as the deteriora
21、tion happens very rapidly. Accelerated ageing methods are used as it is practically impossible to obtain experimental results under normal conditions of utilisation. These methods involve simulations which reproduce the normal conditions of utilisation as closely as possible, but where the parameter
22、s are set so that ageing occurs more rapidly. This standard deals solely with accelerated ageing methods. EN 12280-2:2002 (E) 5 1 Scope This European Standard specifies a method for the determination of light or weathering accelerated ageing effects on physical properties of coated fabrics. Colour f
23、astness to light or weathering is not dealt with by this standard. 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
