Testing Laboratory United States Testing Company, Inc. Est. 1880 Main Laboratories 1415 Park Ave., Hoboken, N. J. Philadelphia, Pa.--Chicago, III.--Los Angeles, Calif.--Denver, Colo.--New Yore, N. Y -- Woonsocket, R. I.--Boston, Mass--Memphis, Tenn. The United States Testing Company, Inc., is one of America's leading independent testing and research laboratories. Established in 1880, it is today an institution known and recognized from coast to coast--an institution whose scientific findings are accepted as impartial and authoritative by every branch of American industry. Thermal Transmission Apparatus For measuring thermal conductivity of rigid, semi-rigid or loose types of n*ulating materials. Boiler Testing We have all the necessary equipment to test and rate heating boilers in accordance with S.B.l --A.S.M.E. Codes Air FUter Duel Testing. Our Engineering Laboratory is equipped with all the necessary appara tus to conduct tests on domestic heating boilers for determination of fuel con sumption, draft-loss, stack temperature, steam quality, Btu output, flue gas analysis, and over-all efficiency. Eating tests are performed according to either the S.B.l. or I.B.R. codes, as well as under simulated operating conditions for development purposes. Water heaters can be subjected to capacity tests under wide temperature requirements and varied heating loads. Refractories, fuel additives, valves, pumps, burners, and heating accessories of many types are evaluated scientifically in our laboratories. Other facilities include all the neces sary equipment for conducting exhaus tive tests on air cleaning devices according to accepted impingement or the more recent discoloration methods. These tests may be performed . with either artificial or natural dusts, under an almost infinite variety of flow rates and dust feed. : Diffusers, grilles, registers, and duct ventilators are regularly tested and rated. SOUND MEASUREMENTS Measurements of sound absorption and sound transmission coefficients are but two of the typical tests made on a great variety of building materials. Field and laboratory tests are regularly conducted for determination of sound intensity in the audible range. Our experts are available for court, testimony in connection with any of the tests we perform, in support of our findings.
