It also certifies the requisite number and type of fittings
and the date of manufacture.
Productivity Engineering and Services Consultants
(PESC), an independent third-party auditing company
appointed by ARMSA, will regularly audit tank
manufacturers who choose to comply.
If compliant, PESC will issue a certificate giving
independent assurance of a manufacturer’s claim that their
products meet the SANS 1731:2017 criteria. Compliant tank
manufacturers will be able to market their compliance with
an ARMSA/SANS-approved sticker on their tanks, as well as
using the certificate and sticker in their general marketing
programmes.
A word of warning from Wiid, “Any tank manufacturer
can claim to meet the SANS 1731:2017 standard, but
without formal certification there is no guarantee. We
therefore urge all stakeholders and home owners to
request the PESC certificate from the manufacturer
prior to purchase for peace of mind that tanks delivered
to sites or homes have been thoroughly tested and
certified.”
Any queries relating to the adoption of the standard or
information on compliant manufacturers can be sent to
[email protected], or to the appointed tank standard auditor
at [email protected]. u
The Association of Rotational Moulders of Southern Africa
(ARMSA) announced the publication of a South African
National Standard, SANS 1731:2017, for polyethylene
chemical and water storage tanks, developed in conjunction
with the South African Bureau of Standard (SABS).
“The SANS 1731:2017 tank standard is proof that the
polyethylene tank you purchase has been properly designed and
manufactured to be fit for purpose for the length of its warranty
life. It compels tank manufacturers to conform to world best
practise,” explains Wayne Wiid, ARMSA chairperson, “and it
protects members of the broader construction, architecture,
plumbing, landscaping, and built industries, as well as
consumers, against tanks of lesser quality.”
The SANS 1731:2017 tank standard provides specific
criteria in terms of the source of raw material, ultraviolet
protection, overall weight, wall thickness, light penetration,
stress crack resistance, and impact strength for a range of
different sizes.
It ensures that the production methods used to
manufacture the tanks comply with best practise, while
requiring that traceability is built into the manufacturer’s
control systems.
The standard includes an audit check for actual storage
volumes versus stated volumes and it evaluates the overall
appearance of the finished tanks.
