Testing Laboratory United States Testing Company, Inc. Est. 1880 Main Laboratories 1415 Park Ave., Hoboken, N. J. Philadelphia, Pa.--Chicago, III--Los Angeles, Caup.--Denver, Colo.--New York, N. Y.-- Woonsocket, R. I.--Boston, Mass.--Memphis, Tenn. The Untied States Testing Company, 7nc., 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 ami authoritative by every branch of American industry. Thermal Transmission Apparatus For measuring thermal conductivity o rigid, semirigid or loose types of inaulating materials. Boiler Testing We have all the necessary equipment to test and rate heating boilers in accordance with I.B.R.--SB.I.--A.SM.E. Codes Air Filler Duct 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. Rating tests are performed according to either the S.B.I. 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. SOUT^D 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.

Y. ditioning theory and applications in more than 300 current publications through out the world. Prepared by a staff of experts, it is invaluable for those en gaged in research, design, or in explora tion of unfamiliar fields. Five issues annually at $7.00. Subscriptions can be predated to include the January, 1946 issue. APPLICATION DATA SECTIONS TONG acknowledged the most au*-* thoritative periodical in the field. Refrigerating Engineering has added steadily to the practical value of its con tents, and its number of readers has grown in proportion. A wide variety of material is presented, all from the view point of its usefulness to the reader in his own business. This magazine is a must for men who keep in touch with all that is new and important in refrigeration and air conditioning. The annual subscrip tion price is $4. ASRE DATA BOOKS Are essential tools in the refrigeration and air conditioning industries. It has been published biennially since 1932 and appears in two volumes, published al ternately--the Basic volume, now in its sixth edition, a standard reference work which deals with refrigeration cycles, fundamental data, industrial, domestic, and commercial systems, and air con ditioning; the Applications volume, consisting wholly of practical how-it-isdone chapters on all the known applica tions of refrigeration and air condition ing. The current edition is dated 1946. Volumes sell for $7.00 and $6.00 respec tively in the U. S. REFRIGERATION ABSTRACTS A JOURNAL devoted to abstracts of -^-all worthwhile articles appearing on the subject of refrigeration and air con OOME 40 bulletins are available sepa^ rately at reasonable prices for single copies or quantity orders and can also be had bound with a paper cover, the com plete set for $10.00. The APPLICATION DATA Sections tell precisely how refrigeration is used in various fields, giving examples and spe cific information on the best practice up to date. Some of the subjects covered to date are: refrigeration of locker plants, fur storage, restaurants, liquids, apples and pears, skating rinks, butter and cheese making, citrus fruits, beer dispens ing, retail stores, wine making, load cal culations, operation of ammonia ma chines, meat packing plants, etc. CODES AND STANDARDS THE ASRE further contributes to refrigeration progress by its partici pation in establishing codes and stand ards in the industry. Among the recent codes made available are: Methods of Rating and Testing Air Conditioning Equipment, Mechanical Condensing Units, Self-Contained Air Conditioning Units for Comfort Cooling, Refrigerant Expansion Valves, Evaporative Con densers, Water-Cooled Refrigerant Con densers; Safety Code for Mechanical Refrigeration; Recommended Practice for Mechanical Refrigeration Installa tions on Shipboard. A complete set is available for $5.00. MEMBERSHIP ACTIVITIES IT is the policy of the ASRE to treat in its meetings current subjects touching upon all phases of the art of refrigeration. Membership is in several grades with dues from $10 to $18. Sec tions hold meetings in 29 principal cities. More detailed information will be sent if you wish.
