ICS 03.120.30

MSD 03

Reaffirmed 2022

NATIONAL FOREWORD

This Indian Standard (Part 8) which is identical with ISO 7870-8 : 2017 ‘Control charts - Part 8: Charting techniques for short runs and small mixed batches’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Statistical Methods for Quality and Reliability Sectional Committee and approval of the Management and Systems Division Council.

This Indian Standard is published in several parts. The other parts in this series are:

Part 0 Guidelines for selection of control charts

Part 1 Control charts for variables

Part 2 Control charts for attributes

Part 3 Specialized control charts

Part 4 Cumulative sum chart

Part 5 Acceptance control charts

Part 6 EWMA control charts

This series of standards was originally published in 1980 and revised in 2003. The philosophy of the control chart approach and the basic principles and concepts underlying control charts have been covered in IS 397 (Part 1) which is a necessary adjunct to this standard. This Part is new in the series.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
