DIN 2270:2017-02

DIN 2270:1985-04 has been fully revised in response to the publication of DIN EN ISO 9493:2011-03, which is a concept standard that only specifies requirements for the most important design and metrological characteristics. The limit values for errors of measurement are no longer included in this concept standard, although German industry had argued against the deletion of these values. However, to ensure that the limit values are not deleted and continue to be available to German industry, this new edition of DIN 2270 has been published, which contains only the limit values for the errors of measurement. The limit values for the errors of measurement specified in the present standard had been laid down in DIN 2270:1985-04 prior to the publication of DIN EN ISO 14253-1. With these limit values, proof of conformity with specifications as required in DIN EN ISO 14253-1:2013-12, 5.2 is normally not possible using the available test methods. For this reason, the method of proving conformity with the specification laid down in ISO/TR 14253-6:2012-11 has been specified here.
