Transcription

1 (800) (562) A Subsidiary of the International Code Council PMG LISTING CRITERIA FOR PERT-AL-PERT PIPE AND FITTINGS FOR REFRIGERATION APPLICATIONS Approved Date: November 2015 PREFACE Plumbing, mechanical and fuel gas (PMG) listings issued by ICC Evaluation Service, LLC (ICC-ES), are based upon performance features of the International Plumbing Code, International Mechanical Code, International Residential Code, Uniform Plumbing Code and Uniform Mechanical Code. Section of the International Plumbing Code reads as follows: Alternative materials, methods and equipment. The provisions of this code are not intended to prevent the installation of any material or to prohibit any method of construction not specifically prescribed by this code, provided that any such alternative has been approved. An alternative material or method of construction shall be approved where the code official finds that the proposed design is satisfactory and complies with the intent of the provisions of this code, and that the material, method or work offered is, for the purpose intended, at least the equivalent of that prescribed in this code in quality, strength, effectiveness, fire resistance, durability and safety. Similar provisions are contained in the Uniform Codes. ICC-ES may consider alternate listing criteria, provided the listing applicant submits valid data demonstrating that the alternate listing criteria are at least equivalent to the listing criteria set forth in this document, and otherwise demonstrate compliance with the performance features of the codes. Notwithstanding that a product, material, or type or method of construction meets the requirements of the criteria set forth in this document, or that it can be demonstrated that valid alternate criteria are equivalent to the criteria in this document and otherwise demonstrate compliance with the performance features of the codes, ICC-ES retains the right to refuse to issue or renew a listing, if the product, material, or type or method of construction is such that either unusual care with its installation or use must be exercised for satisfactory performance, or if malfunctioning is apt to cause unreasonable property damage or personal injury or sickness relative to the benefits to be achieved by the use of the product, material, or type or method of construction. Listing criteria are developed solely for use by ICC-ES for purposes of issuing ICC-ES PMG listings. Copyright 2015

3 Page 3 of BASIC INFORMATION 2.1 Product Description: Complete information shall be provided concerning material specifications, thickness, size and the manufacturing process. 2.2 Installation Instructions: Product shall be installed in accordance with the manufacturer's instructions and the requirements of the applicable codes and reference standards in Section Product and Packaging Identification The piping shall be permanently and legibly marked with the manufacturer's name or trademark, and the model number. The product shall also bear the PMG listing mark. The ICC-ES listing number shall be placed on the listed product's packaging or installation instructions. 3.0 GENERAL REQUIREMENTS 3.1 Fittings and Assembly: Tests shall be conducted using fittings that will be recognized in the evaluation report for use with the tube. Test specimens shall be assembled in accordance with the manufacturer s recommended methods. 3.2 Design: Pipe and fittings shall comply with the applicable design conditions and criteria in either Chapter II of ASME B31.5 and Section 4.1 of this LC or ASTM F PERT-AL-PERT tube complying with ASTM F1282 may also be recognized for installation with fittings complying with ASTM F 1974, provided fittings are recognized in a current ICC-ES evaluation report All pressure retaining components shall be of corrosion-resisting materials or shall be protected against external corrosion. 4.0 TEST METHOD AND PERFORMANCE REQUIREMENTS 4.1 Hydrostatic Design Basis: PERT-AL-PERT: PERT-AL-PERT tube shall have a pressure design basis (PDB) established in accordance with the requirements of PPI Technical Report TR-3 at 180 F (82 C), following the method of

4 Page 4 of 5 ASTM D 2837, with the following exceptions: Test pressure versus time shall be plotted following the methods of ASTM D 2837 and shall be extrapolated to 100,000 hours. The hydrostatic pressure basis shall be the pressure corresponding to 100,000 hours on the straight-line plot. The rated pressure of the tube shall be calculated as follows: P = PDB (DF) where: P = Rated pressure, psi. PDB = Pressure design basis, psi. DF = Design factor = The hydrostatic pressure basis must be established for all tube sizes for which recognition is sought. Alternate test proposals may be considered with written concurrence of ICC-ES. Exception: For PERT-AL-PERT products, the hydrostatic PDB may be determined in accordance with PPI Technical Report TR-3/92 for experimental grades at 180 F (82 C), provided the requirements of the standard grade at 180 F (82 C) are met, and data is submitted to ICC-ES, within the period of time specified in PPI TR Refrigerant Exposure Test Three 18 inches long samples of the pipe and fitting assemblies shall be prepared for this test. The inner tube shall be exposed to the liquid phase of each refrigerant intended to be handled for 30 days at 176 ± 4 F (80 ± 2 C). After the exposure, one sample shall be subjected to the vibration test specified in 4.3 of this criteria; one sample shall be subjected to the pull test specified in section 4.4 of this criteria; one sample shall be subjected to the pressure test of section 4.5 of this criteria. 4.3 Vibration Test Pipe and Fitting assembly shall be tested in accordance with clause of UL1963, and there shall be no leakage or failure. 4.4 Pull Test Pipe and Fitting assembly shall be tested in accordance with clause of UL1963, and force measured shall not be less than 120 lbs. 4.5 Pressure Test:
