SABS conducts the following tests against the
specifications contained in SANS 1307. Conformance to
SANS 1307 requires testing to SANS 151 as
SANS 151 is referenced as a normative requirement
in SANS 13074:
• The performance of a geyser is tested against SANS
151.
• Safety tests are conducted against SANS 60335-
2-21 –
Safety of household and similar electrical
appliances Part 1, and requirements for storage
water heaters Part 2.
• Mechanical performance tests according to SANS
1307 – Domestic solar water heaters.
• Thermal performance tests (Efficiency or
performance or Q factor of systems) against SANS
6211-1 – Thermal performance tests.
• Tests for SANS 10106 – installation and
maintenance of solar water heating systems.
Testing for certification purposes
For the purpose of the SABS Certification scheme the
November 2019 Volume 25 I Number 9
SABS auditor will identify the samples to be taken to
the SABS Laboratories during the site assessment. It
is important to note that a self-sampled system may
not be used for certification purposes because there is
no traceability back to a batch that was manufactured.
Samples selected for testing need to conform to the
visual inspection criteria before it is submitted to the
Testing Laboratory.
Testing will be conducted on the samples against the
relevant SANS. Only successful test reports will enable
a manufacturer to proceed with the certification of the
geyser type.
Local content verification
SABS will conduct verification according to SANS
1286:2017 and local production and content
designation requirements as contained in the National
Treasury Instruction Note. This is to ensure that
local manufacturing takes place in the country and
that minimum local content threshold is achieved.
The Department of Trade and Industry (the dti) has
designated SWH components at 70% for solar collectors;
and 70% for storage tanks (geysers). PA
