标准简介

OVERVIEW

中文简介

该标准规定了工件上圆角的尺寸系列,旨在减少制造和检验所需的刀具、量具和测量仪器的数量。它提供了圆角在技术图纸中表示的示例,并指定了符合R5、R10和R20优先数系的圆角值。

English summary

This standard specifies the sizes of radii on workpieces to limit the number of tools, gauges, and measuring instruments required for manufacture and checking. It provides examples of representing these radii in technical drawings and defines preferred values based on R5, R10, and R20 series.

April 2002

Radii on workpieces and their representation in technical drawings

DIN

250

ICS 17.040.30

Supersedes
July 1972 edition.

Radien

In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker.

Foreword

This standard has been prepared by Technical Committee Technisches Zeichnen of the Normenausschuss Technische Grundlagen (Fundamentals in Technology Standards Committee).

The objective of this standard is to limit the number of tools, gauges and measuring instruments needed for the manufacture and checking of radii. Therefore, only the radii specified in this standard should be used in the design of workpieces.

Amdments

This standard differs from the July 1972 edition in that it has been editorially revised and the examples have been brought into line with current practice.

Previous editions

DIN 250: 1922-01, 1924-04, 1939-12, 1972-07.

All dimensions are in millimetres.

1 Scope

This standard specifies radii on workpieces and gives examples of their representation in technical drawings. The radii conform to the preferred number series R 5, R 10, and R 20 as in DIN 323-1, with some of the values taken from the corresponding rounded value series R" 5, R' 10, and R" 10.

2 Normative references

This standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the titles of the publications are listed below. For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references, the latest edition of the publication referred to applies.

DIN 323-1 Preferred numbers and preferred number series – Basic, calculated and rounded values

DIN 406-11 Engineering drawing practice – Dimensioning – Principles of application

Continued on pages 2 and 3.
