All other materials shall be testedand classified in accordance with EN 13501-1.5 TestingTesting, except for reaction to fire, shall be carried out as specified in EN 14016-2.6 Evaluation of conformity6.1 GeneralEvaluation of conformity is carried out by declaring conformity of binders for magnesite screeds, caustic magnesiaand magnesium chloride, with the requirements of this standard on the basis of:¾ Initial type testing (ITT);¾ Factory production control (FPC).The conformity criteria and assessment procedure are given in clause 9.
2)See Commission Decision 96/603/EC, as amended.
EN 14016-1:2004 (E)76.2 Initial type testing (ITT)An initial type testing shall be carried out to show conformity of the product to this standard. Additionally, an initialtype testing shall be carried out at the beginning of production of a new product type. Before starting productionand introduction of the product into the market, suitable initial type testing shall be carried out to confirm that thepredicted product properties conform to the requirements in this standard and correspond to the declared values.Initial type tests shall also be carried out if the specification for the binders or the manufacturing method have beenchanged.Tests previously performed in accordance with the provisions of this standard may be taken into account providedthat product characteristic(s), test method, sampling procedure and system of attestation of conformity are identi-cal.6.3 Factory production control (FPC)Factory production control means the permanent internal control of production exercised by the manufacturer or hisagent under the responsibility of the manufacturer himself.The purpose of the factory production control is to ensure that binders for magnesite screeds placed on the marketconform to their technical specifications given in clause 4. Sampling and tests shall be carried out as described inEN 14016-2, except as provided for in 6.4.The manufacturer shall record the results of production control (manufacturer’s record). These records shall includeat least the following:¾ identification of the product tested;¾ date of sampling;¾ test methods used;¾ test and inspection results;¾ date of tests;¾ identification of the person responsible for the tests;¾ calibration records.An FPC system conforming to the requirements in EN ISO 9001 and corresponding to the requirements in thisstandard is considered as a system
