ACCREDITATION’S, APPROVALS, CERTIFICATIONS AND RECOGNITIONS
A total of 55 test methods SANAS accreditations in terns of ISO 17025 and GPL compliance prescribed in accreditation to conformity assessment, calibration and good laboratory practices Act, 2006 (Act 19 of 2006). The lab aims to add a set of 72 new test methods (to the current scope of accreditation) over a period of five years starting in 2023/24FY in order to improve service offering.
Have a certified ISO 9001:2015 Quality Management System covering all lab activities plus supporting functions. Implementation of this system is driven by national supply chain requirements and by the management’s desire to maintain broad company’s quality requirements which cannot be fulfilled by ISO 17025 requirements.
A total of six (6) Natural Professional Scientist registered in terms of Natural Scientific Professions Act of 2003. Current scope of registration covers Chemistry, Physics, Radiation Physics, Microbiologist and Metrology. Other professional certifications/ recognitions include Engineers, Water Process Controllers, Nuclear Forensic Specialists, Radiation Professional Specialists, Radiochemists, Geohydrology, Radiation Physicist, Environmental Scientist; etc.
The ZAL 14 stationed at Necsa site is one of the 16 radionuclide laboratories in the world certified by CTBTO (Comprehensive Nuclear-Test-Ban Treaty) to measure air particulate samples. This lab is part of a unique global network (i.e. International Monitoring System) of facilities using state-of-the-art technologies to detect potential nuclear explosives tests. The relevant quality standard here is INF.96. In three years the scope of this service will expanded to include analysis of samples for Radio-Xenon.
Our personnel are trained in Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP). Our standard test methods (for radiopharmaceutical products) meet GMP/GLP requirements which guarantees that products are consistently and continually manufactured according to proven quality standards requirements. Additional labs are planned for GLP certification during 2024/25FY.
