Testing strength of glass panels. Washington, D.C., June 21. With glass blocks being used more and more these days in the construction [of] buildings, The National Bureau of Standards is conducting extensive tests to determine how much wind pressure the panels will stand. So far the panels have resisted 633 pounds wind load. Pictured conducting the tests are, left to right: Dr. C.H. Hahner, R.C. Carter, and A.S. Endler, all of the Bureau, 6/21/38
