Abstract :
Standardization has been cited many times as one of the reasons for the extensive application and low cost of an article which is widely used by the public. It has become a factor of ever increasing importance to modern industry and is one of the foundation stones upon which large industrial and commercial enterprises are based. In the manufacture of everything from structual steel and automobiles to watches and chewing gum, it plays a large and important part — and in the lamp manufacturing industry, along with all the others, it has become a veritable watchword of progress and service.
