We have purchased one heater, one junction box, one conduit, all Exd certified, for conduit with suffix "U".
Do we need to recertify the three things as a new product. there is confusion from description in IEC 60079-0:2011, Section 16.3 and Section 28.2
Section 16.3, looks like it is OK, because not change anything about the equipement.:
16.3 Cable glands
Cable glands, when installed in accordance with the instructions required by Clause 30, shall not invalidate the specific characteristics of the type of protection of the electrical equipment on which they are mounted. This shall apply to the whole range of cable dimensions specified by the manufacturer of the cable glands as suitable for use with those glands. Cable glands may form an integral part of the equipment, i.e. one major element or part forms an inseparable part of the enclosure of the equipment. In such cases, the glands shall be tested with the equipment.
Non-threaded cable glands shall be certified as Ex Components or certified with the complete equipment.
Threaded cable glands and cable transit devices shall be certified as Ex Cable Glands, certified as Ex Components, or certified with the complete equipment.
Cable glands, whether integral or separate, shall meet the relevant requirements of Annex A.
Section 28.2
28.2 Certificate
The manufacturer shall prepare, or have prepared, a certificate confirming that the equipment is in conformity with the requirements of this standard along with its other applicable parts and additional standards mentioned in Clause 1. The certificate can relate to Ex equipment or an
Ex Component.
An Ex Component certificate (Identified by the symbol “U” suffix to the certificate number) is prepared for parts of equipment that are incomplete and require further evaluation prior to incorporation in Ex equipment. The Ex Component certificate may include a Schedule of Limitations detailing specific additional evaluation required as part of incorporation into Ex equipment. An Ex Component certificate shall clarify that it is not an Ex equipment certificate.
