ISO 16140:2003

ISO 16140:2003 defines the general principle and the technical protocol for the validation of alternative methods in the field of microbiological analysis of food, animal feeding stuffs and environmental and veterinary samples for the validation of alternative methods which can be used in particular in the framework of the official control, and the international acceptance of the results obtained by the alternative method.
It also establishes the general principles of certification of these alternative methods, based on the validation protocol defined in ISO 16140:2003.
Where an alternative method is used on a routine basis for internal laboratory use without the requirement to meet (higher) external criteria of quality assurance, a less stringent comparative validation of the alternative method than that set in ISO 16140:2003 may be appropriate.
