Technical Requirements a.ii. Technical documents to be submitted b Type testing requirements PRODUCTION REQUIREMENTS MARKING REQUIREMENTS BACKGROUND AND REFERENCE DOCUMENTS APPROVAL DATE AND REVISION NUMBER BACKGROUND INFORMATION / REFERENCES PRODUCT DESCRIPTION 1.a General description of the product (a) Cable splices shall consist of a conductor connector, replacement insulation, replacement cable sheath, and where applicable, replacement of armour and shielding. (b) Heat-shrinkable tubing means tubing that will reduce in diameter from an expanded size to a predetermined size by the application of heat. 1.b Application limitations (a) These rules are applicable only for cable splices using heat-shrinkable tubing. The other type of cable splices, e.g., cold shrink, moulding compounds and tape shall not be considered within this specific product. (b) These rules are not applicable to cable splices used for propulsion unit, high voltage circuits or used in dangerous spaces, e.g., Zone 0, Zone 1 and Zone 2 dangerous spaces, except for intrinsically safe circuits. (c) Cable splices shall have the original electrical, mechanical, flame-retardant and, where necessary, fire resistant properties of the cables. 1.c Intended use Cable splices approved by these rules are intended for use under the following conditions: (a) Joint of cables installed in structural sub-assemblies; Page 1 of 4

5 (b) Joint of cable circuits extended or shortened by modifying cable arrangement. (c) To replace damaged section of cables; (d) Joint of special type cable, e.g. submersible cable, and shipboard cable. 1.d System context See 1.c 2. DESIGN EVALUATION 2.a Engineering evaluation requirements 2.a i. Technical Requirements a) Cable splices shall be in accordance with IEC , ASTM F and ASTM D ; b) The Conductors are to be connected using a compression type butt connector. In such case, a one-cycle compression tool and proper dies shall be used. Long barrel butt connectors with conductor stops shall be used for conductor sizes of 6mm2 or larger. c) The cable splices for multi conductor cables are to be staggered in such a way that the connectors for each conductor are not contiguous to the connector of an adjacent conductor. In addition, the conductor insulation is to be removed no more than necessary to accept the connector. d) For screened cables, replacement screenings are to be provided and such screenings are to be secured by a method that does not exert more pressure than necessary to establish adequate electrical contact. Screened cables are to have at least a 13mm overlap between any replacement shielding material and original screening material. e) Replacement cable sheath materials shall have physical properties that are the same as, or equivalent to, the cable length. Replacement cable sheaths are to be centred over the splices and to overlap the existing cable sheaths by at least 51mm. Replacement cable sheaths shall be installed so that a watertight seal with the existing cable sheaths is created. 2.a.ii. Technical documents to be submitted (a) All documents shall be submitted in English; (b) The types and temperature range of heat-shrinkable tubing for which approval is requested; (c) Data sheet or specification of heat-shrinkable tubing; (d) Instruction manual how to repair the cables; Page 2 of 4

6 2.b Type testing requirements The following tests shall be carried out for cable splices in accordance with ASTM D in the presence of RO's surveyor. In case the tests are conducted at a Nationally Accredited Laboratory, the presence of the surveyor may be omitted: (a) Dimensions; (b) Restricted Shrinkage; (c) Dielectric Breakdown Voltage and Dielectric Strength: (d) Heat Shock; (e) Storage Life; (f) Low-Temperature Properties; (g) Tensile Strength and Ultimate Elongation; (h) Heat Resistance; (i) Colour; (j) Colour Stability; (k) Fluid Resistance; (l) Flammability; (m) Volume Restivity; (n) Water Absorption; (o) Secant Modulus; (p) Stress Modulus; (q) Corrosion Testing; (r) Thermal Endurance; (s) Adhesive Peel Strength; (t) Melting Point; 3. PRODUCTION REQUIREMENTS Refer to EU RO Product Quality Assurance (PQA)" procedure (Annex VI of EU RO Framework Document for the Mutual Recognition of Type Approval. 4. MARKING REQUIREMENTS Manufacturers of the approved equipment are, in principle, to mark the product before shipment for identification of approved equipment and, in addition, at least the following items to be marked at the suitable place: (a) Manufacturer s name or equivalent; (b) Type No. or symbol; (c) Serial No. and date of manufacture; (d) Particulars or ratings.
