✦ Synopsis

THE Bureau is issuing a supplement to Circular No. 38, on the testing of rubber. At a conference of manufacturers and users of rubber insulation, held in New York, December 7, 191 I, it was decided to take steps to improve and standardize methods for analyzing rubber compounds. In pursuance of the decision reached, a committee, now known as the Joint Rubber Insulation Conmaittee, was appointed to devise specifications and an analytical procedure for rubber insulating compounds.

After the first report of this committee had been adopted unanimously by the conference, it was submitted to the Bureau of Standards, at the request of the committee, for tentative approval and possible publication. Because of actual participation by the Bureau in the work of the committee, and because of the importance of the report it is now published as a supplement to Circular No. 38, " The Testing of Mechanical Rubber Goods." It is believed that the report is a long step in the direction of standard specifications and suitable methods of analysis, the preparation of which is peculiarly germane to the work of the Bureau of Standards, and that it should prove of great value to, consumer and manufacturer alike.

The Bureau of Standards is issuing a preliminary circular on " The Testing of Barometers." It is issued in advance of the final results of the Bureau's investigations only in response to repeated requests for information. It will serve to describe in a general way the testing of mercurial and aneroid barometers at the Bureau of Standards, and to announce the fees which are charged for the various tests.
