English: Title: Bureau of Standards breaks up plates for a reason. Washington, D.C., May 23. Just about everything manufactured in this country is made the subject of tests in the Bureau of Standards here. Even the dinner plates used in restaurants go through a series of tests in order that the government may known just how long it can expect them to last in usage. R.F. Galler, Chief of the White Wear section, is here operating an impact machine to determine the amount of force necessary to cause those germ-concealing chips in a plate. Previous in this test, the plate is ground with porcelain to find out how long a plate may be handled before it loses its gleam, and samples are heated to find out how much heat is necessary to cause cracks to appear in the glazing
