STATISTICAL CONTROL OF QUALITY

IN this issue is brought to a conclusion the series of three articles on “ Quality Control in Production Engineering ” by MR. H. RISSIK who is one of the pioneers of the use of statistical charts for controlling the quality of products during manufacture. He is a member of the B.S.I. Committee on Statistical Methods in Standardization and Specifications, and was, we believe, responsible for the first experiment in the application of quality control to production engineering in England—at the Croydon works of MESSRS. CREED & CO.—in 1940. In addition to this, he has been occupied during the last six months or so in giving special lecture courses on the subject at Technical Colleges in various parts of the country.
