6.4 Safety in use 6.4.1 Thermal performance at normal operating conditions 6.4.1.1 Rigid liners and fittings When a liner and its fittings are tested according to the heat stress test method of EN 1859 with the exception of the test rig (Figures 4 and 5) which shall be (replaced by the test rig) described in A.7.2, they shall meet the gas tightness of 6.3. 6.4.1.2 Rigid connecting flue pipes and fittings When a rigid connecting flue pipe and its fittings are tested according to heat stress test method of EN 1859 with the exception of the test rig (Figures 4 and 5) which shall be replaced by the test rig described in A.7.2, the maximum surface temperature of combustible material adjacent to the test sample at the distance declared shall not exceed 85°C when related to an ambient temperature of 20°C and shall meet the gas tightness of 6.3. In addition, vitreous enamelled connecting flue pipe shall not exhibit any cracking or any sign of flaking of their surface after heat stress test according to EN 10209. 6.4.1.3 Flexible liners and fittings When a flexible liner and its fittings are tested according to heat stress test method described in A 7.4.2, they shall meet the gas tightness of 6.3. The test sample shall allow the test ball of A.7.3.1.2 to move freely down. 6.4.2 Accidental human contact In case of accidental human contact for a connecting part, individual member states regulations are applicable. 6.4.3 Thermal resistance Where connecting flue pipes are insulated, their thermal resistance value, declared by the manufacturer, shall be determined in accordance with 6.4.3 of EN 1856-1:2003.

10 Evaluation of conformity 10.1 General Clause 10 of EN 1856-1:2003 shall apply where the words «system chimney products» shall be replaced by «liners, connecting flue pipes and fittings». 10.2 General The compliance of a liner, connecting flue pipe and fitting product with the requirements of this document and with the stated values (including classes) shall be demonstrated by:  initial type testing;  factory production control by the manufacturer, including product assessment. 10.3 Type testing 10.3.1 Initial type testing Initial type testing shall be performed to show conformity with this document. Tests previously performed in accordance with the provisions of this document [same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.] may be taken into account. In addition, initial type testing shall be performed at the beginning of the production of a new system chimney product or at the beginning of a new method of production (where this may affect the stated properties). Where characteristics are determined on the basis of conformity with other product standards (for, metals including coatings, seals and sealants), these characteristics do not need to be reassessed provided that the designer ensures the validity of the results. Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated of them, although this does not replace the responsibility of the manufacturer to ensure that the liner, connecting flue pipe and fitting product as a whole is correctly designed and its component products have the necessary performance values. All characteristics defined in Clauses 5 and 6 shall be subject to initial type testing, with the following exception:  release of dangerous substances which may be assessed indirectly by controlling the content of the substance concerned.

- the operations referred to under i) and j),
- only the operations under i) or,
- only those under j). The operations under i) centre as much on the intermediate states of the product as on manufacturing machines and their adjustment, and equipment, etc. These controls and tests and their frequency are chosen based on product type and composition, the manufacturing process and its complexity, the sensitivity of product features to variations in manufacturing parameters, etc. The manufacturer shall have or have available the installations, equipment and personnel which enable him to carry out the necessary verifications and tests. He may, as may his agent, meet this requirement by concluding a sub-contracting agreement with one or more organisations or persons having the necessary skills and equipment. The manufacturer has responsibility to calibrate or verify and maintain the control, measuring or test equipment in good operating condition, whether or not it belongs to him, with a view to demonstrating conformity of the product with its technical specification. The equipment shall be used in conformity with the specification or the test reference system to which the specification refers. If necessary, monitoring is carried out of the conformity of intermediate states of the product and at the main stages of its production. This monitoring of conformity focuses where necessary on the product throughout the process of manufacture, so that only products having passed the sche
