DIN 878:2006-06 (E)
Foreword This standard has been prepared by Technical Committee NA 152-03-07-02 Eindimensionale Längenprüftechnik of the Normenausschuss Technische Grundlagen Grundlagen (Fundamentals in Technology Standards Committee). DIN 878:1983-10 has been fully revised to reflect the publication of DIN EN ISO 463:2006, the latter being a framework standard that defines the most important design and metrological characteristics of mechanical dial gauges but does not specify numerical values for the metrological characteristics; Germany had been against the decision to delete these values. This new edition of DIN 878 has been published to ensure German industry continues to have access to the limit values of metrological characteristics. Amendments This standard differs from DIN 878:1983-10 878:1983-10 as follows. a)
Only numerical numerical values for for limits of metrological metrological characteristics characteristics are specified. specified.
b)
The title has been changed to reflect the content.
c)
The standard has been editorially revised.

Scope
This standard applies to mechanical gauges as in DIN EN ISO 463 having scale intervals of 0,01 mm and a measuring range of 0,4 mm; 0,8 mm; 3 mm; 5 mm and 10 mm. It specifies the numerical values for limits of metrological metrological characteristics. characteristics. This standard does not cover waterproof or watertight mechanical gauges, which are subject to special requirements.

Limit values for metrological characteristics characteristics
The limit values for metrological characteristics are to be taken from Table 1. They apply to all gauge orientations.
