In so doing SABS contributes to the economic growth of South Africa and Africa as a whole within a framework that protects consumers and the environment by promoting uncompromised quality of products and services.
SABS BUSINESS UNITS Chemicals Electro technical Food and Health Services SABS Mining and Minerals Mechanical and Materials Transportation 3 Purpose of PTS The SABS Commercial (Pty) Ltd (Food Chemistry), is a provider of a proficiency testing scheme (PTS) and recognized by a accreditation body SANAS (South African National Accreditation System) according to ILAC G 3 (Guidelines for the requirements for the competence of providers of proficiency testing schemes). It is recognised that schemes conducted may have primary aims such as establishing the effectiveness and precision of test methods, equipment and evaluating the individual performance of laboratory staff. 4
Purpose of PTS Proficiency testing schemes are used by laboratory accreditation bodies as part of an assessment process to verify competence of a laboratory. A high level of confidence is given to an accredited proficiency testing scheme (PTS) based on international acceptable requirements. Running a PTS Programme improves the quality system of the laboratory. 5 SABS WATER CHECK (PTS) SABS WaterCheck (PTS) is a high frequency interlaboratory Inorganic Chemistry Water proficiencytesting programme with the objective of providing a rapid reportback service to participants for selfevaluation SABS WaterCheck allows flexibility in participation and no specific methods or instrumentation are prescribed. The programme is divided into three categories, each category being scheduled on a quarterly basis. 6
PTS Provider, SABS is supply the following: Preparation of samples for the following groups Group Heavy metals in water: aluminium, barium, beryllium, boron, cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, silicon, strontium, vanadium, zinc, mercury, arsenic and selenium. Scheduled : January, April, July, and October. 7 Provides the following Group Nutrients and oxygen demand: kjeldahl nitrogen, nitrate, ammonia, total phosphate, orthophosphate, oxygen absorbed, chemical oxygen demand, dissolved organic carbon and total organic carbon. Scheduled : February, May, August, November. 8

Sample : Purified sewage effluent preserved with,5 ml / litre H SO 4 (conc).. * Dilution: Samples, 3, 4 and 5 are synthetic water samples. Dilute by pipetting 0 ml of the synthetic concentrate of samples,3,4 and 5 respectively into separate 000 ml volumetric flasks and dilute to volume with distilled/deionised water Use Grade A volumetric glassware. NB: Do not correct analytical results for these dilutions. 3. Testing: Please analyse by single test on a routine basis and express results as one decimal. 4. Ranges: The range values are only valid for the diluted synthetic samples. F5.9/04E 007/08
