WearCheck Water operates under the umbrella of specialist condition monitoring company, WearCheck, which is the only oil analysis company in Africa with ISO 9001 quality certification and ISO 14001 certification for its environmental management programme, including ISO 17025 accreditation for its laboratory-centric quality management programme. WearCheck Water recently earned SANAS accreditation for AdBlue/ DEF (diesel exhaust fluid) testing.
General manager of WearCheck Water, Thelma Horsfield, is proud of her team’s achievements. “It is no easy task to set up the method and gain accreditation. We work for many months to fine-tune methods that we can present confidently to SANAS for approval. Our ISO/IEC 17025 accreditation is for the membrane filtration method used in detecting total coliforms and E. coli in water samples. This accreditation underscores the lab’s commitment to delivering precise and reliable water-quality testing services,” she says. “By securing ISO/IEC 17025 accreditation for this method, WearCheck Water’s Johannesburg laboratory demonstrates our technical expertise and commitment to safeguarding public health through accurate and dependable water quality testing.”
Horsfield elaborates, ‘”This accreditation not only reflects a high level of technical competence, but also entrusts the individual with substantial responsibility. A Technical Signatory (TS) holds the authority to validate and approve test results, ensuring they meet international standards of accuracy and reliability.
“The journey to becoming a TS is rigorous and demands extensive knowledge, experience and dedication. The process involves comprehensive training in quality management systems, proficiency in specific testing methods, and a thorough understanding of ISO/IEC 17025 requirements. Candidates must demonstrate their technical competency through assessments, internal audit, and continuous professional development. This role carries immense responsibility, as the TS is accountable for the integrity and validity of laboratory results. TS decisions directly impact public health, environmental safety and regulatory compliance. Upholding these standards requires unwavering commitment, attention to detail, and adherence to best practices.”
WearCheck Water provides professional water analysis services to multiple industries across southern Africa, including mining, agriculture, fleet management and manufacturing.
