Excerpt from Industrial Standards: Issues 101-130This publication is one of a series covering industrial standards for materials, which will include standards prepared by the Government and by technical societies and other organizations. The purpose of this series is to facilitate commerce between the United States and foreign countries by gathering together and making available standards for materials of various kinds, commercially acceptable and representing good American practice, through their translation into various foreign languages. In most cases such standards are the result of com promise. Their publication 1n this series is an indication that they are working standards, subject, however, to amendment as new scientific data are obtained. It is appreciated that the development of an ideal standard of quality usually requires service experience and experimental researches on each detail of the standard. In such work standardizing institutions, technical societies, individual investigators, and industrial laboratories cooperate in developing a true standard of quality.The standard printed in this number of the series was prepared by the American Society for Testing Materials, whose central offices are at Philadelphia, Pa. The objects of this society, as broadly stated in its charter, are the promotion of knowledge of the materials of engineer ing and the standardization of specifications and the methods of test ing. The society has existed under its present name and charter since 1902, superseding the American section of the International Association for Testing Materials, which latter had its origin in a conference held in 1882. In addition to the annual volume of its Proceedings, the society issues triennially, beginning with the 1918 edition, a volume of A. S. T. M. Standards devoted chie¿y to the publication of the standards adopted by the society.The standards of this society are drafted by committees on which both the consuming and producing interests are represented, either equally or with a majority of the former. After discussion and criticism at general meetings of the society the proposed standards may be referred by a two-thirds affirmative vote to a letter ballot of the society, subject to adoption by a two-thirds affirmative vote. The standards of the society are extensively used throughout the United States.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
