Conformity evaluation
11.1
General
Conformity of special cement with the requirements specified in this standard shall be evaluated in accordance with DIN EN 197-2 (excluding clause 8) and certified as specified in subclauses 11.2 and 11.3. 11.2
Granting and withdrawal of certificate of conformity
The inspection body shall provide the certification body with the following documentation: a) a report on initial inspection (if any; cf. subclause 5.5.5 of DIN EN 197-2); b) a report giving at least the results of the third party inspection tests carried out on the first sample taken for initial testing (cf. subclause 5.6.3 of DIN EN 197-2).
11.2.1
If the inspection report indicates that the requirements specified in subclause 5.5 of DIN EN 197-2 are met, and if the results mentioned in subclause 11.2.1, item b) fulfill the requirements specified in clauses 4 to 7 and the conformity criteria specified in clause 9, the certification body will issue a certificate of conformity. 11.2.2
Throughout the rest of the initial period, the results of third party inspection testing and of factory production control (including in-process testing) shall be evaluated and reported to the certification body (cf. subclause 5.6.3 of DIN EN 197-2). 11.2.3
If the evaluation referred to in subclause 11.2.3 is satisfactory, the certificate of conformity remains valid as long as the specifications of DIN EN 197-2 or the manufacturing conditions are not changed (unless it is to be withdrawn for the reasons listed in table 1 of DIN EN 197-2). 11.2.4
When production of a particular cement type is discontinued, the manufacturer shall notify the inspection and certification bodies as soon as the stock of cement is depleted. The relevant certificate of conformity shall then be withdrawn without delay. The certificate of conformity is also to be withdrawn if third party inspection can no longer be carried out. 11.2.5
Cement which is similar to a certified cement produced at the same factory, but which has a significantly different composition or properties within the specified limits, may be identified and treated as a different type of cement. 11.2.6
11.3
Marking
Conformity of a special cement with this standard shall be declared in a certificate of conformity issued by the certification body and indicated by an inspection mark applied to the product by the manufacturer. 11.3.1
11.3.2 The certificate of conformity shall include the information given in the Muster für Übereinstimmungs zertifikate nach § 24b MBO (Specimen form for certificate of conformity under article 24b of the German Model Building Code). 11.3.3 As proof of conf ormity of a cement, bags or delivery notes shall bear the inspection mark in addition
to the information specified in clause 10. This mark shall include the following details: a) name of manufacturer; b) number of DIN Standard (DIN 1164) forming the basis of the evaluation of conformity, and standard designation; c) logo or identification of certification body.
12 Requirements for dispatch centres Compliance of special cement with the requirements specified in this standard shall be assessed on the basis of clause 9 of DIN EN 197-2 (excluding table 2) and table 5 of this standard.

Explanatory notes Re subclause 4.4
In the case of low-alkali cement (NA type), a maximum alkali content (expressed as Na 2O equivalent) has been specified for technical reasons. In the case of Portland cement (CEM I type), it may be assumed that the whole alkali content becomes effective when the alkali reacts with silicic acid, which is no t the case with other NA type cements. Therefore, the limit values for the cements based on blastfurnace slag have been specified so as to make their performance equivalent to that of CEM I type cement.
