Goals 2018
Grandfather Exception Certification1 application in 2017 and certification released
MILK ANALYZERS CERTIFICATION
New Model Instrument Certification
According ICAR protocol and ISO 8196-3 IDF 128-3
Objective evidences of the instrument performance
Indications on the best use for ICAR purposes
ICAR LABs
Conclusions
ICAR is offering this initial Quality Assurance tools in milk analyses to create technical connectionsvaluable exchange of practical aspects regarding the protocols application
The network is useful to collect also the future needs of DHI milk laboratoriesFor the coming analytical challenges !
...new activities and service will come
