Full title and description
ISO 7246:1984 — Pipes and fittings of acrylonitrile/styrene/acrylester (ASA) — General specification for moulding and extrusion materials. This International Standard specifies the basic designation properties for ASA plastics intended for pipe and fitting applications (acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength and flexural modulus).
Abstract
Specification of ASA plastics for pipe applications. The standard identifies the material properties to be used when designating ASA grades for moulding and extrusion of pipes and fittings — including acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength (Izod or Charpy) and flexural modulus. Normative test methods referenced include ISO 1133, ISO 178 and ISO 179.

Scope
This International Standard establishes a general specification for acrylonitrile/styrene/(substituted styrene)/acrylester (ASA) materials intended for use in the manufacture of pipes and fittings by moulding and extrusion. It defines the key property requirements and the basis for designating ASA grades for piping applications; the numerical values are indicative and not intended for direct design calculations. The standard does not replace specific product or system standards which set design and installation requirements.
Key topics and requirements
- Designation properties for ASA used in pipes and fittings: acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength (Izod or Charpy) and flexural modulus.
- Reference to test standards for property determination: ISO 1133 (melt flow rate), ISO 178 (flexural properties) and ISO 179 (Charpy impact).
- Applicability to materials for moulding and extrusion processes used in pipe and fitting manufacture.
- Values are given for specification and identification of ASA grades; they are not intended as engineering design data.
Typical use and users
Used by plastics material suppliers, pipe and fitting manufacturers, product designers, quality and testing laboratories, compliance and standards departments, and procurement/specification engineers who need to identify or specify ASA grades suitable for moulded or extruded piping components. National standards bodies and conformity assessment organizations may also reference the standard when developing product standards or test protocols.
Related standards
Normative and related references commonly cited with ISO 7246:1984 include ISO 1133 (Determination of melt flow rate), ISO 178 (Determination of flexural properties), ISO 179 (Charpy impact), and other plastics piping standards and guidance documents developed under ISO/TC 138 and related committees. Product/system standards for ABS/ASA piping systems (for soil/waste or other applications) and regional standards may also be relevant.

FAQ
Q: What is this standard?
A: ISO 7246:1984 is an ISO International Standard that provides a general specification for acrylonitrile/styrene/acrylester (ASA) materials intended for the moulding and extrusion of pipes and fittings.
Q: What does it cover?
A: It covers the designation properties used to identify ASA grades for pipe applications (acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength — Izod or Charpy — and flexural modulus) and references the test methods used to determine those properties. It is a material specification, not a system-design or installation standard.
Q: Who typically uses it?
A: Materials suppliers, pipe/fitting manufacturers, test laboratories, product designers, standards writers and specification engineers who need to classify or specify ASA plastics for piping components. Standards bodies and conformity assessors also refer to it.
Q: Is it current or superseded?
A: The published edition is from 1 November 1984 (Edition 1). The ISO catalogue shows the publication was reviewed and confirmed (last confirmation recorded in 2021), so this edition remains the current ISO publication unless a future revision is issued.
Q: Is it part of a series?
A: It sits within the body of ISO plastics piping and materials standards handled by ISO/TC 138 (and subcommittee SC 5 for general properties of pipes, fittings and valves). It is related to other ISO standards that specify materials and test methods for plastics used in piping systems.
Q: What are the key keywords?
A: ASA, acrylonitrile/styrene/acrylester, pipes, fittings, moulding materials, extrusion materials, melt flow rate, Vicat, impact strength, flexural modulus, ISO 7246.
