6. Scope of the Licence: “Licence is granted to use Standard Mark as per IS 15450: 2004 with the following scope: Name of the product Polyethylene/Aluminium/Polyethylene composite pipes for hot and cold-water supplies Pipe Designation PM/ IS 15450/ 1/ April 2020 2

Grouping Guidelines 1. IS 15450 :2004 covers Polyethylene/Aluminium/Polyethylene (PE-AL-PE) composite pipes for hot and cold-water supplies. 2. PE-AL-PE composite pipes are designated by nominal inside and outside diameters. The Pipes are grouped as under based on Pipe Designation: Group I II III Pipe Designation 0912, 1014, and 1216 1620 and 2025 2532, 3240 and 4050 3. Considering the above, following grouping guidelines is developed for GoL/CSoL: • One sample with highest Pipe Designation from each group shall be tested for all requirements to cover all Pipe Designation from that particular group in the scope of licence. 4. The Firm shall declare the varieties of pipes they intend to cover in the licence. The scope of the Licence may be restricted on the Manufacturing and Testing capabilities of the Manufacturer. 5. During the operation of the licence, BO shall ensure that all the varieties of Pipes covered in the Licence are tested in rotation to the extent possible. PM/ IS 15450/ 1/ April 2020 3
