A°V ^ V . , Lists of manufacturers who hayb expressed their desire to supply material in accordance with certain $N£deral specifications promulgated hy the Fed- eral Specifications Board ,• and their willingness to certify to the porchas- ers, upon reqtiest, that the material thus supplied complies with the re- quirements and tests of these specifications, and is so guaranteed by them. The lists are continuously subject to revision and enlargement. From time to time additions are being made to both the number of lists of "willing- to-pertify" manufacturers and the number of manufacturers on the individ- , ual lists. Purchasers who might be inclined to do business with unknown or untried manufacturers whose names appear on the "wiliing-to-certify" lists should not fail to insist upon receiving from such manufacturers properly signed certificates guaranteeing compliance with the specification requirements. In order to avoid delay and confusion, when placing orders and requesting pert if ientes from "willing-to-certify" manufacturers, the correspondence should always be conducted with the individual officer of the company whose name appears on the "willing-to-certify" list. This officer can be assumed to be familiar with the specification and with the plan for issuing cer- tificates, whereas other officers of the same company may be unfamiliar therewith. It is to be definitely understood that tho certificates are to be issued by the manufacturers to the purchasers, and not to the Bureau of Standards, which assumes no responsibility of any kind in connection with the trans- action. The purchaser must take such steps a.s he considers desirable to determine whether or not the commodities delivered .do actually comply with the specifications. A list of all knowh ..commercial testing laboratories throughout the country, •classified according to commodities and localities, has been prepared by the Bureau of Standards for the convenience of both the producers .^nd the consumers - the manufacturers and the purchasers. This list, together with a list of college research laboratories, is issued as Bureau of Standards Miscellaneous Publication No. 9 ^, under the title, "Directory of Commercial Testing and College Research Laboratories" . It is for sale exclusively by the Superintendent of Documents, United States Government Printing Office, Washington, D. C. Price 15 cents per copy. February 15 , 1930 DEPARTMENT OF COMMERCE BUREAU OF STANDARDS WASHINGTON FAC ILITAT1ITG- THE USE OF SPECIFICATIONS An analysis of the status of the making and the utilization of specifi- cations reveals the fact that many excellent soecif ications well recognized throughout industry are not being widely used at the present time because of the inability on the part of most purchasers to determine whether or not commodities delivered correspond to the specification requirements. A grea impetus to the popularizing of the use of specifications could be given by eliminating this disadvantage to the small-quantity purchaser. As a solution to the problem of eliminating the above-mentioned disad- vantage and thereby facilitating the use of specifications, use is being made of the so-called "certification plan". Certification Plan In carrying out this plan there are compiled lists of manufacturers who have expressed their desire to supply material in accordance with certain selected specifications, and their willingness to certify to the purchaser, upon request, that the material thus supplied, is guaranteed to comply with the requirements and tests of the specifications. From time to time the State and other public purchasing agents have sought the assistance of the United States Department of Commerce in the formulation of standards, specifications, and methods of tests for their purchases. Every effort is, therefore, being exerted to make the certifi- cation plan as effective as possible for "public purchasers", that is, pur- chasers for the Federal, State, county, and municipal governments who are spending the money collected from the public in the form of taxes. , Below are indicated 248 of the Federal specifications to which the cer- tification plan has been applied. There have oeen compiled by the National Bureau of Standards 243 lists of such firms as have expressed to the Bureau their willingness, when requested to do so, to certify to purchasers that material supplied on contracts based on the designated 24-3 Federal specifi- cations complies with the requirements and tests of these specifications, and is so guaranteed by them. Additions and corrections to these lists are being made from time to time. These lists are not published; their distribution is limited to govern- mental and institutional purchasers, Federal, State, county, and municipal. They are sent to others only upon specific request or to officers of inter- ested associations and societies for comment and criticism. The groups of commodities covered by the specifications together with numerical reference to the individual specifications, are as follows: BRUSHES AND BROOMS GLASS 191 201 396a 4o6b 512a 123 192 202 397a 407 519a 193 203 398 511 520a INKS 194 204 399b 512a 521a 195a 205 400a 513a 522a I63 165 265a 379 196 206 401b 5l4a 523 164 166 266a 197 207 402a 515a 524b 193 20Sa 403a 5l6a 525a LEATHER GOODS 199 33.2 404b 517a 526a 200 333a 405a 37 133 134 24l BUILDERS!
