Results Interpretation
Explanatory Information
1.These results are subject to change and must not be considered as final, unless this test report is
signed by appropriate laboratory technical signatories. Should any results change, you will be
informed thereof, before issuing the final test report.
2.Results and or determinands/parameters marked with an asterix (*) are not SANAS accredited and
are not included in the SANAS Schedule of Accreditation for this laboratory.
3.Results pertain to the sample/s as taken by you and in the condition received by this laboratory.
4.All laboratory testing is done at the Head Office laboratory. Any sub-contracted testing will be
clearly marked on the test report.
5.Information pertaining to the testing methods, is obtainable from the laboratory.
6.For SANS 241 conformance testing, acid extractable metals are analysed. All other results are
reported as total unless indicated otherwise.
7.In assessing the conformity of test results to the specification on the test report, Umgeni Water
Laboratory Services shall report test results using thefollowing decision rule: “A binary rule
(pass/fail) decision rule using the guard band as per ILAC G8_09_2019; at a 95% Confidence
Interval, shall apply to all reported results”. Therefore, the probability of reporting a false rejection of
a test result against a specification is at <2.5% Confidence Interval. When a statement of conformity
is not required, test results are reported as an absolute value.
8.Statement of Conformity of results: Based on the laboratory’s decision rule, all results that are
depicted in bold font shall be deemed as non-compliant to the defined specification per
determinand/parameter, where applicable.
9.Statements 7 and 8 (above) apply to accredited methods results only.
10.Samples are held for 7 working days, where possible, after the provision of results and unless
results are queried with a formal request for re-testing, it is implied that all test results are accepted
and the sample/s will be discarded.
11.Opinions and Interpretation of results are based on the test results obtained from the sample/s
tested and falls outside the scope of accreditation.
