Tyco Electronics Corporation 305 Constitution Drive Menlo Park, CA 94025 USA Raychem Tubing Specification This Issue: Date: Replaces: RW-2013 Issue 6 August 18, 2008 Issue 5 Raychem HRHF, HRNF, and HRSR High Shrink Ratio Heat Shrinkable Tubing 1. SCOPE This specification covers the requirements for three types of electrically insulating, extruded tubing whose diameter will reduce to a predetermined size upon the application of heat in excess of 120C. They are suitable for use with Hot Melt Adhesive /97 or Sealant /226. 1.1 HRSR. HRSR tubing is a semi rigid, flame retardant, cross-linked modified polyolefin. The standard color is black and can be supplied with a Sealant or Hot Melt Adhesive. 1.2 HRHF HRHF tubing is a highly flexible, flame retardant cross-linked modified polyolefin. The standard color is black (and clear for non-flame retardant material) and can be supplied with a Sealant or Hot Melt Adhesive. 1.3 HRNF HRNF tubing is a semi rigid, non-flame retarded, cross-linked modified polyolefin. The standard color is black and can be supplied with a Sealant or Hot Melt Adhesive. 2. 2.1 REQUIREMENTS Composition and Appearance The tubing shall be fabricated from thermally stabilized, modified polyolefin and shall be irradiation cross-linked. It shall be homogeneous and essentially free from flaws, defects, pinholes, bubbles, seams, cracks and inclusions. 3. PROPERTIES The tubing shall meet the requirements of Tables 1 and 2. 4. 4.1 4.1.1 QUALITY ASSURANCE PROVISIONS CLASSIFICATION OF TESTS Qualification Tests Qualification tests are those performed on the tubing submitted for qualification as a satisfactory product and shall consist of all the tests listed in this specification. 4.1.2 Production Routine Tests Production routine tests shall be carried out on every batch, unless otherwise specified and shall consist of the following: dimensions, longitudinal change, tensile strength, ultimate elongation, heat shock, low temperature flexibility and flammability. Flammability is not applicable for HRNF and clear tubings. 5. 5.1 SAMPLING INSTRUCTIONS Qualification Test Sample Qualification test samples shall consist of 50 feet (15m) of tubing. Qualification of any size qualifies all sizes. The color shall be black. If this document is printed it becomes uncontrolled. Check for the latest revision. Page 2 SPECIFICATION RW-2013 ISSUE 6 5.2 Production Routine Test Samples Production routine test samples shall consist of a sufficient length to perform all the tests in 4.1.2 selected at random from each batch. A batch shall consist of all tubing of the same size, from the same production run and offered for inspection at the same time. Physical property tests performed at this time qualify subsequent tubing lots produced from the same compound batch. 6. TEST PROCEDURES Unless otherwise specified the tubing shall be recovered in a forced air circulating oven for 10 minutes at 150 2C. All tests shall be performed without the adhesive. Uncoated samples are available upon request. 6.1 Dimensions and Longitudinal Change The test method shall be as specified in ASTM D 2671. The length and inside diameter of three 250 mm long specimens of expanded tubing shall be measured. The specimens shall be recovered and the length and inside diameter of each shall be measured. The longitudinal change shall be expressed as a percentage of the original length. The minimum and maximum recovered wall thicknesses shall be determined. 6.2 Tensile Strength and Ultimate Elongation The test method shall be as specified in ASTM D 638. For tubing of recovered inside diameter greater than 6 mm, five Type IV dumbbell specimens shall be tested. For tubing of recovered inside diameter less than or equal to 6 mm, five tubular specimens 150 mm long shall be tested. Rate of jaw separation shall be 500 10 mm per minute. The test shall be carried out at a temperature of 23 2C. 7. 7.1 PREPARATION FOR DELIVERY Form The tubing shall be supplied in cut lengths unless otherwise specified. 7.2 Packaging Packaging shall be in accordance with good commercial practice. 7.3 Marking Each container of tubing shall be permanently and legibly marked with the size, quantity, manufacturer's identification and batch number. If this document is printed it becomes uncontrolled. Check the latest revision. SPECIFICATION RW-2013 ISSUE 6 8.
