Polysmart Pty Ltd, a leading Australian polyethylene welding training
organisation and ISO weld testing facility, has officially received NATA accreditation
for tensile testing of butt fusion and electrofusion polyethylene welded joints.
The National Association of Testing Authorities (NATA) accreditation
officially approves Polysmart for conducting tensile tests of polyethylene welded
product according to ISO 13953, Bend Tests to ISO 21751,
and Peel Decohesion Tests on pipe and related products including pipe
fittings to ISO 13954. This recognition makes Polysmart part of a very select
group of internationally recognised laboratories in Australia eligible to offer
these testing services.
The NATA recognition also ensures that the mechanical testing of
polyethylene welded joints and products conducted by the Polysmart laboratory
meet a very stringent and demanding set of protocols. Companies requiring
testing can be assured that the Polysmart processes and reporting activities
are among the best practices utilised anywhere in the world and meet NATA
standards. The NATA accreditation also assures clients that Polysmart test
methods meet the exacting requirements of the International Standards
Organisation (ISO) and also those of the Australian and New Zealand Standards (AS/NZ).
With the increasing use of polyethylene piping in infrastructure and
construction, testing of welds has seen a corresponding rise over the last few
years making NATA accreditation more important than ever for quality assurance.
The integrity of piping welds is critical as welded joints are considered the
weak points of a pipeline.
The Australian Pipeline Industry Association (APIA) and its Coal Seam
Gathering (CSG) code of practice now requires testing to be carried out on a number
of welds cut out of existing pipelines prior to commissioning as an industry
Industry stakeholders need to have confidence that the welds joining the
pipes delivering gas or water are completely safe and free of defects. Polysmart’s
NATA accredited testing can assist by testing and determining whether weld
standards have been met.
