Valve Standards

Standards provide greater assurance of product performance and consistency, and are available to assist design engineers

in system specification. The most frequently referenced industry standards for plastic piping systems are ASTM Standard

Specifications and Practices. Along with ASTM Standards, additional product specifications and certifications form the basis

of product conformance to which Spears

valves are manufactured.

ASTM — American Society for Testing

and Materials

ASTM D 1784

Specifies compound physical requirements for PVC and

CPVC materials used in the manufacture of thermoplastic

valves, pipe, and fittings. The standard classifies compounds

on the basis of several physical and chemical properties.

Conformance to a particular material classification requires

meeting the minimum requirements specified.

ASTM D 1785 and F 441

Specifies physical dimensions, test requirements, and maxi-

mum operating pressures, for Schedule 40, 80 and 120 PVC

(D 1785) and CPVC (F 441) pressure pipe.

ASTM D 2466 and F 438

Specifies physical dimensions, test requirements, and work-

manship for Schedule 40 PVC (D 2466) and CPVC (F 438)

pressure fittings.

ASTM D 2464 and F 437

These standards have been incorporated into ASTM D 2467

and F 439, respectively.

ASTM D 2467 and F 439

Specifies physical dimensions, test requirements, and work-

manship for Schedule 80 PVC (D 2467) and CPVC (F 439)

pressure fittings.

ASTM D 2564, F 493, and F 656

Specifies requirements for PVC (D 2564) and CPVC (F 493)

solvent cement, including component compounds, minimum

resin content, viscosity, and physical performance. Standard

F 656 specifies requirements for primers to be used with

PVC solvent cements.

ASTM D 2846

Specifies physical dimensions, test requirements, and work-

manship for CPVC Hot-and-Cold Water Distribution Systems,

commonly referred to as CTS (Copper Tube Size).

ASTM D 2855

Specifies standard practice and procedures for making PVC

pipe and fitting joints with solvent cement.

ASTM D 4101

Specifies classification of injection molding and extrusion

grades of Polypropylene (PP) materials according to physical

characteristics. Conformance to a particular material classifi-

cation requires meeting the minimum requirements specified.

Individual Standards Overview

ASTM F 1498

Specifies dimensions and gauging of tapered pipe threads

on plastic pipe and fittings.

ASTM F 1970

Specifies performance criteria testing, and end connection

dimensions for products such as ball valves and check valves.

ANSI — American National Standards Institute

ANSI B1.20.1

Specifies basic thread form, taper, and tolerances of general

purpose tapered pipe threads (metal).

ANSI B16.5

Specifies standard bolt hole patterns and basic dimensions

for Class 150 steel pipe flanges.

NSF

International

NSF

is a third party product approval agency which tests

manufacturer’s product against a variety of health and product

performance standards. They are one of the most recognized

agencies for issuing approval of plastic piping system products

for potable water use.

NSF

Standard 14

Certifies product suitability for potable water use, product

conformance to applicable ASTM standards, and establishes

minimum requirements for manufacturer’s quality control

programs through routine testing and facilities inspections.

NSF

Standard 14 Special Engineering

Appurtenance Program (S.E.)

In addition to Standard 14 general requirements, the S.E. pro-

gram establishes product performance requirements where

no directly applicable ASTM specifications exist. NSF

S.E.

specifications are developed from a combination of applicable

portions of ASTM specifications and manufacturer’s design

specifications as a standard for conformance verification.

NSF

Standard 61

Developed to establish minimum requirements for the control

of potential adverse health effects from products in contact

with drinking water. Certifies product suitability for use in

potable water systems through toxicological testing for con-

taminates or impurities. NSF

Standard 61 compliance is a

prerequisite to NSF

Standard 14 certification.
