Application
Corrosion resistant CLEAR pressure pipe, IPS sizes 1/4” through 12”, for use at temperatures up to and including 140 °F. Pressure rating (70 psi to 570 psi) varies with schedule, pipe size, and temperature as stated on this specification. Generally resistant to most acids, bases, salts, aliphatic solutions, oxidants, and halogens. Chemical resistance data should be referenced for proper material selection. Pipe exhibits excellent physical properties and optimum clarity. Typical applications include process, sight glass, and dual containment piping as found in chemical processing, high purity applications, food processing, pharmaceuticals, laboratory use, waste treatment, plating, and other applications involving fluid transfer where visual monitoring of process lines is warranted.

Scope
This specification outlines minimum manufacturing requirements for CLEAR Polyvinyl Chloride (PVC) Schedule 40 and Schedule 80 iron pipe size (IPS) pressure pipe. This pipe is intended for use in systems where the fluid conveyed does not exceed 140°F. This pipe meets and or exceeds applicable industry standards and requirements as set forth by the American Society for Testing and Materials (ASTM).

PVC.Materials
The material used in the manufacture of the pipe shall be a rigid polyvinyl chloride (PVC) compound, with a Cell Classification of 12454 as defined in ASTM D1784. This compound shall comply with the provisions of  Title 21 United States FDA Code of Federal Regulations and shall be safe for use with food contact applications. This compound shall be transparent in color, and shall be approved by NSF International for use with potable water (NSF Std 61).

Dimensions
PVC Clear Schedule 40 and Schedule 80 pipe shall be manufactured in strict accordance with the dimensional requirements of ASTM D1785 to Schedule 40 or Schedule 80 dimensions and tolerances as applicable. All PVC Clear pipe/valves shall meet the minimum burst pressure requirements and water pressure rating requirements of PVC Type II, Grade I, established for PVC 2110 as defined in ASTM D1785. Each production run of pipe shall also meet or exceed the test requirements for materials, workmanship, flattening, and extrusion quality defined in ASTM D1785. All belled-end pipe shall have tapered sockets to create an interference-type fit, which meet or exceed the dimensional requirements and the minimum socket length for pressure-type sockets as defined in ASTM D2672.

Marking
All Clear PVC Schedule 40 and Schedule 80 pipe shall be permanently embossed with the manufacturers name or (or the manufacturers trademark when privately labeled), pipe size, dimension (i.e. Sch 40 or Sch 80), and date and time of manufacture.

Sample-Specification:

All PVC Schedule 40 & Schedule 80 CLEAR pipe shall be manufactured from a Type I, Grade I Polyvinyl Chloride (PVC) compound with a Cell Classification of 12454 per ASTM D1784. The pipe shall be manufactured in strict compliance to ASTM D1785, consistently meeting and/or exceeding the applicable Quality Assurance test requirements of this standard with regard to material, dimensions, workmanship, burst pressure, flattening  and extrusion quality. The pipe shall be manufactured in the USA by an ISO 9001 certified manufacturer. All PVC CLEAR pipe shall be packaged immediately after its manufacture to prevent damage, and shall then be stored indoors at the manufacturing site until shipped from factory.
