TEST METHODS 3.1 Preparation of Test Specimens Page 3 of 8 Date Printed Unless otherwise specified, tests shall be carried out on specimens of sleeving in the as received condition. 3.2 Dimensions The test method shall be as specified in ASTM D876. Three specimens shall be measured for minor inside diameter, major outside diameter, pitch and wall thickness. 3.3 Breaking Load and Ultimate Elongation The test method shall be as specified in ASTM D638. For sizes 7/16 and smaller, three specimens of whole sleeving 150 mm in length shall be tested. For sizes larger than 7/16, three strip specimens 150 mm long and 5 mm wide shall be cut and tested. The specimens shall be tested using an initial jaw separation of 50 mm and a rate of jaw separation of 50 mm per minute. Mean values for ultimate elongation as established from jaw separation and the mean load to break shall be recorded. 3.4 Specific Gravity The test method shall be as specified in Method A of ISO 1183. 3.5 Crush Resistance Three specimens of sleeving of length as specified in Table 2 shall be crushed transversely between parallel plates of diameter 50 mm minimum in a suitable tensile testing machine at a rate of 5 mm per minute. The Crush Resistance shall be recorded as the mean force required to reduce the outside diameter of the sleeving by 25%. 3.6 Compressive Flexibility Three specimens of sleeving 300 mm long shall be compressed longitudinally in a suitable tensile testing machine at a rate of 5 mm per minute. The sleeving shall slide freely over a supporting mandrel of diameter 90  2% of the sleeving inside diameter. The Compressive Flexibility shall be recorded as the mean value of the force required to compress the sleeving by 25%. 3.7 Flexibility Three specimens of sleeving 300 mm long shall be secured to a flat horizontal surface such that each specimen extends 150 mm beyond a 90° edge. The free end of each specimen shall be loaded as specified in Table 2 and the vertical displacement shall be measured. The flexibility shall be recorded as the mean value of displacement.

The specimens shall then be wound and unwound on the mandrel for 10,000 cycles at a rate of 10 cycles per minute. After cycling the specimens shall be subjected to the dielectric withstand voltage test as specified in Clause 3.13. 3.9 Abrasion Resistance The abrasion resistance shall be determined using equipment similar to that described in MIL-T-5438. Three tubular specimens shall be tested. Each specimen shall be drawn onto a mandrel of diameter equal to the nominal inside diameter of the sleeving. The lengths of the specimens shall be as specified in Table 2. Each specimen in turn shall be abraded with grade 4/0 abrasive tape at a rate of 1.5m per minute under load and of length as specified in Table 2. After testing each specimen shall be examined visually for holes. 3.10 Low Temperature Flexibility Three tubular specimens of sufficient length to be wound totally around a cylindrical metal mandrel of 10 times the outside diameter of the sleeving under test shall be conditioned as specified in Table 1. While still at the conditioning temperature the specimens shall be wrapped 360° around the mandrel in approximately 30 seconds. Each specimen shall be visually examined for cracking and after stabilising to room temperature shall be subjected to the dielectric withstand voltage test as described in Clause 3.13. 3.11 Heat Shock Three tubular specimens 150mm long shall be suspended vertically in a fan assisted air circulating oven as specified in Table 1. After conditioning the specimens shall be allowed to cool naturally in air to ambient temperature and then examined for evidence of splitting, cracking, dripping or flowing. 3.12 Heat Ageing For sizes 7/16 and smaller, three tubular specimens 150 mm long shall be tested. For sizes larger than 7/16 three strip specimens 150 mm long and 5 mm wide shall be tested. The specimens shall be laid on an oven tray and conditioned in a fan assisted air circulating oven as specified in Table 1. After conditioning the specimens shall be removed, allowed to cool naturally to room temperature and tested for breaking load and ultimate elongation as described in Clause 3.3.

A conducting wire shall be inserted through each length of three 600 mm long specimens of sleeving which shall be formed into a ‘U’ shape. The two wire ends of each specimen shall be twisted together. The specimens shall then be filled with a 1% salt water solution serving as an inner electrode and immersed to within 150 mm of their ends in a container of 1% salt water solution serving as an outer electrode. The specimens shall remain immersed for one hour after which a potential of 5 kV shall be applied between the electrodes. The potential shall be gradually increased from zero to 5 kV within approximately 30 seconds and shall be held at that voltage for one minute. 3.14 Copper Mirror Corrosion The test method shall be as specified in ASTM D2671. 3.15 Flammability The test method shall be as specified in ASTM D876. 3.16 Water Absorption The test method shall be as specified in Method 1 of ISO 62. 3.17 Fluid Resistance The test method shall be as specified in ISO 1817. Five test specimens prepared as in Clause 3.3. shall be completely immersed in each of the fluids for the times and temperatures specified in Table 1. The volume of the fluid shall not be less than 20 times that of the specimen. After immersion, lightly wipe the specimens and allow to air dry at 23 ± 2°C for 1h ± 15m. The Breaking Load and Ultimate Elongation of each specimen shall be tested according to Clause 3.3. The test shall be repeated on the remaining specified fluids. 3.18 Fungus Resistance The test method shall be as specified in ISO 846 Method B. Specimens shall be conditioned for 56 days followed by testing as per Clause 3.3. If this document is printed it becomes uncontrolled.
