As of 27th February 2015, 15 methods for microbiological water analysis are certified NF VALIDATION. The methods for quantification of Legionella using PCR are certified according to a protocol based on NF T90-471 and ISO/TS 12869 standards. The other methods are certified according to a specific technical protocol, developed by AFNOR Certification that compares the alternative method to a standard method.
During their meeting held on 26th February 2015:
The Water Technical Board “General protocol” validated a new method: Enterolert-E/Quanti-Tray or Quanti-Tray 2000 for the enumeration of intestinal enterococci in bathing waters. Other validation files are currently submitted to examination.
The Water Technical Board “PCR Legionella” revised the applicable validation protocol, in order to integrate the requirements of the new NF T90-471 standard (issuing very soon). The validation protocol draft and its transition modalities will be submitted to the approval of the NF Validation Experts Committee, before being published.
Next meeting of Water Technical Board “General protocol” : 8th June 2015.
Next meeting of Water Technical Board “PCR Legionella”: 14th September 2015.
