American Standard Association

ANSI Reporter and Standards Action American National Standards Institute The monthly M/V.97 Eeporternews of poHcy-level actions on standardization taken by ANSI, the international organizations to which it belongs, and the government. Standards Fiction biweekly, Hsts for pubHc review and comment standards proposed for ANSI approval. It also reports on final approval actions on standards, newly pubUshed American National Standards, and proposed actions on national and international technical work. These two pubHcations replace The Magafine of Standards which ANSI, formerly The American Standards Association, discontinued in 1971.

Because of the versatility of roller chain drives, certain standards have been established. With these standards, interchangeability of chains is possible between one manufacturer and another. As long as chains are identifiable, they can be cross-referenced easily without any serious operational problems arising. Table 58.7 shows the standard roller chain American Standards Association (ASA) number by pitch length for single, double, and triple strand chains.

Responding to an evident need and at the request of The American Society of Mechanical Engineers, the American Standards Association initiated Project B31 in March 1926, with ASME as sole administrative sponsor. The breadth of the field involved required that membership of the Sectional Committee be drawn from some 40 engineering societies, industries, government bureaus, institutes, and trade associations. 

Flash Point (flash p). This is the lowest temperature at which a liquid will give off enough flammable vapor at or near its surface such that in intimate mixture with air and a spark or flame it ignites. The flash point of liquids is usually determined by the Standard Method of Test for Flash Point with the Tag Closed Cup Tester (ASTM D56-52, available from the American Society for Testing Materials, 1916 Race St, Philadelphia, Pa). This method is also the standard of the American Standards Association (ASA Z 11.24-1952, available from the American Standards Association, 70 East 45th St, New York, NY). The Interstate Commerce Commission uses the Tag Open Cup (TOC) Tester giving results 5—10°F higher (less flammable). Other methods frequently used are... 

ANSI is the premier USA standardisation body and, in being the official ISO representative, is the counterpart of BSI. It was previously known as the American Standards Association. ANSI does not itself write standards but approves as American standards those produced by ASTM and other similar organisations. More details can be found at www.ansi.org. 

As much as possible the symbols used in the text follow the recommended practice of the American Standards Association. However, special symbols had to be introduced, the idea of avoiding confusion being the criterion. In selecting the letter d to represent particle-size, rather than r the radius of a particle, I was motivated by considerations of particle-measurement. This step naturally resulted in some difficulty since it can be confused with the differential d. Wherever the two appear together, their separate meanings have been denoted by writing particle-diameter as d) thus, d(d) means the differential of the particle-diameter. The letter r for the radius of a particle was retained in only one instance, in order to conform to accepted procedure. 

Iron and steel pipes were originally classified on the basis of wall thickness as standard, extra-strong, and double-extra-strong. Modem industrial demands for more exact specifications have made these three classifications obsolete. Pipes are now specified according to wall thickness by a standard formula for schedule number as designated by the American Standards Association. 

Schedule number is defined by the American Standards Association as the approximate value of... 

Currently the American Standards Association Sectional Committee Z39 on Library Work and Documentation, Subcommittee on Abbreviations for Periodicals, is working on a standard which will serve as a guide for abbreviating periodical titles. In 1954 the International Standards Organization issued the first edition of ISO Recommendation R4, International Code for the Abbreviation of Titles of Periodicals. This standard was rejected by the American Standards Association on the basis that the general principles established by it were too broad and would lead to varying interpretations and would not achieve the standardization desired. Since ISO R4 became an international standard it has been the subject of several changes or amendments which have been proposed at the ISO Technical Com-...

Physicist and electrical engineer. Attended Universities of Nebraska and Rochester. Joined Eastman Kodak at Rochester, New York in December 1912. Appointed Director of the Camouflage Research Center in the Eastman Kodak Research Laboratories, serving as a Lieutenant USNR from March 1918 to February 1919. Became Superintendant in Charge of the Physics Department, Eastman Kodak from 1929. Noted for his research into sensitometry (film speed behaviour). This led to the establishment of film speed criterion which has been employed internationally - since 1934 by Eastman Kodak, from 1943 by the American Standards Association and from 1947 by the British Standards Institute.
