<i>Title:</i> New machine to test brake linings designed by Bureau of Standards. Washington, D.C., March 16. A new machine, both in design and operations, has been installed at the National Bureau of Standards for the testing of brake linings. The machine permits the study of brake linings under conditions closely approaching those of actual sevice and yet which can be accurately controlled. It will make less difficult the complex job of revising the Federal Government's specification for auto brake linings. Wil. Holt of the Bureau is shown in the photograph, 3/16/38
