Unless otherwise specified, the latest issue of referenced documents applies. The following documents form a part of this specification to the extent specified herein. 2.1 GOVERNMENT-FURNISHED DOCUMENTS Military SAE-AMS-1424 Anti-Icing and Deicing - Defrosting Fluid MIL-DTL-83133 Turbine Fuels, Aviation, Kerosene Types, NATO F-34 (JP-8), NATO F-35 and JP-8 + 100 MIL-PRF-5606 Hydraulic Fluid, Petroleum Base, Aircraft, Missile and Ordnance MIL-PRF-7808 Lubricating Oil, Aircraft Turbine Engine, Synthetic Base, NATO Code Number 0-148 2.2 Other Publications American Society for Testing and Materials (ASTM) ASTM D412 Standard Test Methods for Rubber Properties in Tension ASTM D910 Standard Spec. for Aviation Gasolines ASTM D2240 Standard Method of Test for Indentation Hardness of Rubber and Plastics by Means of a Durometer ASTM D2671 Standard Methods of Testing Heat-Shrinkable Tubing for Electrical Use ISO 846 Plastics - Evaluation of the Action of Microorganisms (Copies of ASTM publications may be obtained from the American Society for Testing and Materials, 1916 Race Street, Philadelphia, Pennsylvania 19103). 3.0 3.1 REQUIREMENTS MATERIAL The tubing shall be fabricated from a stabilized, flame resistant, modified Chlorinated Polyolefin and shall be radiation crosslinked. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams, cracks and inclusions. 3.2 Color The tubing shall be black. 3.3 PROPERTIES The tubing shall meet the requirements of Table 3.

All rights reserved Page 2 SPECIFICATION RT-510 ISSUE 11 4.0 4.1 QUALITY ASSURANCE PROVISIONS CLASSIFICATION OF TESTS 4.1.1 Qualification Tests Qualification tests are those performed on tubing submitted for qualification as a satisfactory product and shall consist of all tests listed in this specification. 4.1.2 Acceptance Tests Acceptance tests are those performed on tubing submitted for acceptance under contract. Acceptance tests shall consist of the following: Dimensions Longitudinal Change Tensile Strength Tensile Stress Ultimate Elongation Heat Shock Flammability Low Temperature Flexibility Physical property tests performed at this time qualify subsequent sleeving lots produced from the same batch of compound. Statistical process control data may be used to demonstrate conformance for dimensions. 4.2 4.2.1 SAMPLING INSTRUCTIONS Qualification Test Samples Qualification test samples shall consist of 50 feet (15 m) of tubing of each size. Qualification of any size within each size range specified below will qualify all sizes in the same range. Size Range 1/8 through 7/8 1 through 4 4.2.2 Acceptance Test Samples Acceptance test samples shall consist of not less than 16 feet (5 m) of tubing selected at random from each lot. A lot shall consist of all tubing of the same size, from the same production run and offered for inspection at the same time. 4.3 TEST PROCEDURES Unless otherwise specified, tests shall be performed on specimens which have been fully recovered by conditioning for 10 minutes in a 175 5C (347 9F) oven. All ovens shall be of the mechanical convection type in which air passes over the specimens at a velocity of 100 to 200 feet (30 to 61 m) per minute. Tubing shall be allowed to cool to room temperature prior to testing. The Heat Shrinkable Sleeving and Measurement Gages shall be at room temperature with ambient relative humidity prior to testing before or after heat shrinking.

All rights reserved SPECIFICATION RT-510 ISSUE 11 4.3.1 Page 3 Dimensions and Longitudinal Change Three 6 inch (150 mm) specimens of tubing, as supplied, shall be measured for length 1/32 inch ( 1 mm) and inside diameter in accordance with ASTM D2671, conditioned for 10 minutes in a 175 5C (347 9F) oven, cooled to 23 3C (73 5F) and then re-measured. Prior to and after conditioning, the dimensions of the tubing shall be in accordance with Table 1 and the longitudinal change shall be in accordance with Table 3. Longitudinal change shall be calculated as follows: C = Where: C L0 L1 = = = L1 - L0 x 100 L0 Longitudinal Change [Percent] Length Before Conditioning [inches (mm)] Length After Conditioning [inches (mm)] 4.3.2 Tensile Strength, Tensile Stress and Ultimate Elongation Test three specimens of tubing for tensile strength and ultimate elongation in accordance with ASTM D2671 and for tensile stress in accordance with ASTM D412. The rate of jaw separation shall be 20 2 inches (500 50 mm) per minute. 4.3.3 Copper Stability Three 6 inch (150 mm) specimens of tubing shall be slid over snug fitting, straight, clean, bare copper mandrels, either solid or tubular. The specimens on the mandrels shall be conditioned for 24 hours in a desiccator or similar humidity chamber at 90 to 95 percent relative humidity and 25 3C (77 5F). The specimens on the mandrels then shall be conditioned for 168 hours in a 121 2C (250 4F) oven. After conditioning, the specimens shall be removed from the oven, cooled to 23 3C (73 5F). The copper mandrels shall then be removed from the tubing, then the tubing and copper mandrels shall be examined. Darkening of the copper due to normal air oxidation shall not be cause for rejection. The tubing shall be tested for Ultimate Elongation in accordance with 4.3.2. 4.4 REJECTION AND RETEST Failure of any sample of tubing to comply with any one of the requirements of this specification shall be cause for rejection of the lot represented. Tubing which has been rejected may be replaced or reworked to correct the defect and then resubmitted for acceptance. Before resubmitting, full particulars concerning the rejection and the action taken to correct the defect shall be furnished to the inspector. 5.0 5.1 PREPARATION FOR DELIVERY PACKAGING Packaging shall be in accordance with good commercial practice. The shipping container shall be not be less than 125 pound-test fiberboard. 5.2 MARKING Each container of tubing shall be permanently and legibly marked with the size, quantity, manufacturer's identification and lot number.
