ASTM F1970 defines the standard for fittings, appurtenances, and valves designed for PVC or CPVC plastic pipe systems, or as transitions to metal piping. These components are intended for use only with pressurized liquids that are chemically compatible with the piping materials. Because pneumatic testing may be restricted by some manufacturers due to inherent safety risks, users should check with the manufacturer for specific testing procedures.
ASTM F1970 Specification for Special Engineered Fittings, Valves for Use in Polyvinyl Chloride (PVC) or Chlorinated Poly (VC) Systems
What is ASTM F1970?
ASTM F1970 Sample Preparation Guide
All samples must be preconditioned for at least 40 hours at 73 ± 3.6°F (23 ± 2°C) before testing.
ASTM F1970 Testing Procedure and Requirements
In the ASTM F1970 standard (Standard Specification for Special Engineered Fittings, Appurtenances or Valves for use in Poly (Vinyl Chloride) (PVC) or Chlorinated Poly (Vinyl Chloride) (CPVC) Systems), the dimensions of the seal must conform to the manufacturer’s standard design specification and tolerances. The seal must be designed to apply a sufficient compressive force to the mating parts after assembly, ensuring a positive seal under all possible combinations of fitting and seal tolerances. Sockets must match the dimensions of the fittings that correspond to the pipe size being joined. When measuring thermoplastic threads using gauges, the tolerance must be 61.5 turns. When measuring metallic threads using gauges, the tolerance must be 61 turns. Fittings must meet the minimum standards for hydrostatic pressure resistance. Valves must be tested for conformity in both open and closed positions. Valves that do not have a specific flow direction must be checked in the shut-off position in all potential flow directions. The 1000-hour test on the valves must be undertaken only in the open (shell test) configuration at operating (test) temperatures over 145°F (63°C).
Analysis Results and Interpretation
It is stated that the product was manufactured, examined, sampled, and tested in accordance with the specification, and that it was found to meet the specification’s requirements.
ASTM F1970 covers fittings and appurtenances that are molded, manufactured, or assembled from molded or machined components. Rigid thermoplastics, thermoplastic elastomers, elastomerics, and metals are among the materials utilized in components. PVC, CPVC, PE, or PA are commonly used for the body or main component of a fitting, appurtenance, or valve (nylon).
