Foreword
This standard has been prepared by Technical Committee NA 152-03-07-02 Eindimensionale Längenprüf-technik of the Normenausschuss Technische Grundlagen (Fundamentals in Technology Standards Commit-tee).
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 as follows.
a) Only numerical values for limits of metrological characteristics are specified.
b) The title has been changed to reflect the content.
c) The standard has been editorially revised.
Previous editions
DIN 878-1: 1941-02, 1943-08, 1959-06 DIN 878-2: 1955-12 DIN 878: 1970-06, 1979-01, 1983-10
1 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 characteristics.
This standard does not cover waterproof or watertight mechanical gauges, which are subject to special re-quirements.

3 Concepts
For the purposes of this standard, the concepts defined in DIN EN ISO 463, DIN EN ISO 14253-1, DIN EN ISO 14978 and the “International vocabulary of basic and general terms in metrology” (VIM) apply.
4 Requirements
4.1 Reference temperature
20 °C as in DIN EN ISO 1.
4.2 Limit values for metrological characteristics
The limit values for metrological characteristics are to be taken from Table 1. They apply to all gauge orienta-tions.
Table 1 — Limit values for metrological characteristics
Limit values for
errors of indication over a range of Measuring range
