To ensure accuracy, NRM has a robust internal quality system. At the heart of this system is accreditation by UKAS to the internationally recognised standard for competence – ISO/IEC 17025. UKAS accreditation is specific to particular sample types and methods. The accreditation we hold covers a range of chemical tests in the agricultural and environment sectors.
NRM also participates in a range of performance testing schemes including Food Analysis Performance Assessment Scheme (FAPAS) and WEPAL. NRM is an appointed laboratory by the Organics Recycling Group for the testing of composted waste under the BSI PAS 100 Certification Scheme as well as the Renewable Energy Association for the testing of anaerobic digestate under the BSI PAS 110 Certification Scheme.
NRM holds an APHA (Animal & Plant Health Agency) licence to import, move and keep foreign soil and plant tissue for physical and chemical testing.
NRM has systems and protocols in place to assure the quality of all its analytical data. Quality assurance follows the sample from receipt, throughout its analysis, to the point at which results data are reported. It also covers the laboratory's analytical and data management systems.
ISO 17025 is the British, European and International Standard for quality assurance in analytical laboratories. In the UK, laboratories claiming compliance with this standard are inspected and accredited by UKAS.
Accreditation also means that the laboratory's management systems meet the principles of ISO 9001. Many laboratories achieve ISO 9001 but this certification should not be confused with full UKAS accreditation to ISO/IEC 17025. The full standard covers quality control procedures and method specific procedures.
Although laboratories achieving the standard are regarded as UKAS accredited, accreditation can only be claimed for individual methods that have been inspected and approved by UKAS. A list of accredited methods is given on NRM's UKAS schedule.
NRM currently participates in the following PT Schemes:
• Aquacheck (Agricultural Soil Inorganics Scheme)
• BIPEA (Inorganic & Organic Fertilisers Scheme)
• CONTEST (Contaminated Land Testing Scheme)
• FAPAS (Food Analysis Performance Assessment Scheme)
• ILVO (Flanders Research Institute for Agriculture, Fisheries and Food)
• NAPT (Agricultural soils PT scheme)
• RTC (BTEX and GROs in soil)
• WEPAL ISE (Agricultural Soils PT Scheme)
• WEPAL MARSEP (Compost, agricultural slurries, manures & organic fertilisers)
KEY NRM ANALYSIS & TESTS
Listed below are some of the most widely used tests provided by the laboratory. In addition to these NRM has an extensive portfolio of other tests and, where appropriate, can develop specific tests and analytical suites for your business.
