EN 13121-1 specifies the requirementsfor the specification conditions and acceptance conditions for GRP and thermoplastic materials, which are necessaryin order to establish the chemical resistance properties of these materials in accordance with this Part of the standard.EN 13121-2 gives the requirements necessary to establish that the GRP material and any thermoplastic lining willlhave sufficient chemical and thermal resistance to service conditions. Part 2 defines the requirements for theprotective layer and the structural laminate as well as defining methods for proof of suitability to meet thechemical/thermal effects caused by the fluids and of determination of the partial design factor, A2, as required fordesign in accordance with prEN 13121-3. Five methods are described — use of Media Lists, use of resinmanufacturers data, use of thermoplastics manufacturers data, service experience and sample testing. Themanufacturer of the tank or vessel may choose any one of these methods subject to here being sufficient dataavailable in that method for the particular application.Together with the requirements and acceptance conditions for the raw materials determined in EN 13121-1, thedesign and workmanship requirements as determined in prEN 13121-3 and the delivery, handling, installation andmaintenance recommendations given in EN 13121-4, EN 13121-2 completes the total standard's requirements.

n. a. = not applicable5.2 Determination of partial design factor, A2 by using media listsThe media lists when used with protective layers in accordance with clause 4, at different temperatures andconcentrations, are given in annex A.Use of media lists is only applicable when considering use of a resin described in the resin groups in accordance withEN 13121-1. For other polyester, vinyl ester, furance and phenolic resins which are not in a resin group in accordancewith EN 13121-1, then methods 5.3, 5.5 or 5.6 shall be used.The list of media given in Annex A is not a comprehensive list of all media for which this Standard may be used.Additional data may be found using methods 5.3, 5.4 or 5.5

recommendedconditions of cure and post cure will be followed during manufacture.5.3.3 Partial design factor A2The partial design factor, A2, using SPL or CRL, shall be determined in relation to the resin manufacturer'smaximum temperature, Tm, for the service conditions and the maximum design temperature, Td.The interpretation of resin manufacturer's maximum temperature, Tm, data in terms of A2, is given in Table 3.Table 3 — Partial design factor, A2, relating to the maximum designtemperature, Td, and the maximum temperature, TmMaximum design temperature, Td°CA2post curedaTd = Tm1,4Td = Tm – 101,4Td = Tm – 201,3Td = Tm – 301,3Td = Tm – 401,2Td = Tm – 501,2Td = Tm – 601,1Td = Tm – 701,1aConditions as given in 5.2 or subject to agreement with the resin manufacturer.
