REQUIREMENTS 3.1 MATERIAL The tubing shall be fabricated from an irradiated, thermally stabilized, modified poly(vinylidene fluoride) composition. It shall be homogeneous and essentially free from flaws, defects, pinholes, cracks, and inclusions. 3.2 COLOR The tubing shall be black. 3.3 PROPERTIES The tubing shall meet the requirements of Table 3. 4. QUALITY ASSURANCE PROVISIONS 4.1 CLASSIFICATION OF TESTS 4.1.1 Qualification Tests Qualification tests are those performed on samples submitted for qualification as satisfactory products 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: Visual Examination Dimensions Breaking Load Ultimate Extensibility Crush Resistance Compressive Flexibility Heat Shock 4.2 SAMPLING INSTRUCTIONS 4.2.1 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 Ranges 9/32 through 1/2 5/8 through 1-5/8 4.2.2 Acceptance Test Samples Acceptance test samples shall consist of not less than 10 feet (3 m) of tubing selected at random from each lot. 4.2.3 Lot Formation 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 4.3.1 Breaking Load and Ultimate Extensibility Three specimens 6 inches (150 mm) long shall be cut from sizes 7/16 and smaller. Three strip specimens 6 x 3/16 inch (150 x 5 mm) shall be cut from sizes larger than 7/16. The specimens shall be tested in accordance with ASTM D 638, using an initial jaw separation of 2 inches (50 mm) and a 2 inch (50 mm) per minute rate of jaw separation. The ultimate extensibility (jaw separation) and pounds (N) to break shall be recorded. If this document is printed it becomes uncontrolled. Check for the latest revision.
