The DOST IX - Regional Standards and Testing Laboratories (RSTL) offers testing and calibration services to various customers not only in the region but also to the other cities outside the area. With the effort of providing better metrological, microbiological, physical and chemical laboratory tests and analyses, RSTL had continually improved its services paving the way for the Microbiological Laboratory and Physical & Chemical Laboratory to maintain its ISO 17025 Accreditation.
ISO 17025 (General Requirements for the Competence of Testing and Calibration Laboratories) Accreditation is granted to laboratories that assures its customers of precision, accuracy and repeatability of test results. It is applicable to all organizations performing tests and/or calibrations.
Physical and Chemical Laboratory
The ISO 17025 accredited physical and chemical laboratory conducts quantitative analyses on the following types of sample: raw and processed foods, fruit and fruit products, water and wastewater, soap and related products, condiments and spices, feeds, charcoal, limestone, rubber latex and raw seaweeds.
The ISO 17025 Accredited Microbiological Laboratory offers analyses for raw and processed food products and water samples. Among these analyses are: Aerobic Plate Count – Total Coliform Count - Escherichia coli Count - Yeast and Molds - Salmonella Detection - Fecal Coliform Count - Staphylococcus aureus. - Vibrio cholera - Pseudomonas aeruginusa.
The metrology laboratory performs volumetric and mass calibrations. The volumetric calibrations included calibration of vehicle tanks, proving tanks, calibrating buckets and storage tanks. The mass calibration covers calibration of scales and test weights from 2 kg to 50 kg OIMLClass M.
The renewal of ISO 17025:2005 accreditations cover provisions for Microbiological Testing and Chemical Testing. The scope of accreditation for microbiological testings are aerobic plate count, heterotrophic plate count, total coliform count, fecal coliform test, yeast and molds for foods, beverages, water and effluents; while the chemical testings include crude protein, crude fat, moisture content, ash content for food (fish, crustaceans, mollusks and derived products and dried fish), soy sauce and fish meal.
