Description

Specifies ABS-plastics for pipe applications, the properties chosen to designate ABS plastics for pipes are: acrylonitrile content, Vicat softening temperature, melt flow rate, impact strength and flexural modulus. Reference is made to ISO 2580.

Scope

This International standard establishes a general specification for acrylonitrile-butadiene-styrene (or substituted styrene) for pipes and fittings. The values given shall not be used for design purposes.

This International standard does not apply to

• a) materials containing less than 20 % acrylonitrile in the continuous phase;
• b) materials containing more than 5 % of another comonomer or polymer in the continuous phase;
• c) materials containing flame retardants; d) materials containing fibres.
