1927
IN ACCORDANCE with law the National Bureau of Standards makes tests and carries out investigations for other

Government departments. Due to the large amount of this

official work it is impracticable for the bureau to make tests for private individuals if other laboratories can do the work. To

inform interested persons of the location of other laboratories,

the bureau has compiled a list of the 207 commercial testing

laboratories throughout the country, together with indications

of the types of commodities which they are prepared to test. Special care has been exercised to make this list complete.

There is also presented a list of the laboratories of 143 colleges

which are used not only for purposes of instruction but also to a considerable extent for research work.

An outline is given of the certification plan in accordance

with which there have already been compiled 48 lists of manufacturers who have expressed their willingness to certify to purchasers that material supplied on orders based on the indicated

48 United States Government master specifications complies

with the requirements and tests of these specifications.

COMMERCIAL TESTING LABORATORIES

In recognition of the desirability under present conditions of independent commercial

testing service and in anticipation of a marked increase in the demand for such service

in both domestic and export trade, the National Bureau of Standards has compiled the

accompanying list of laboratories throughout the country that are prepared to test various

kinds of commodities to determine whether or not they comply with purchase specifications.The existence of a thoroughly classified list of commercial testing laboratories will have a number of beneficial effects in promoting the use of specifications, not the least important of which will be the inducement offered to the large number of purchasers who

have hitherto hesitated to buy on specifications.

Heretofore purchasers not individually equipped to make their own acceptance tests have been reluctant to adopt the specification method of buying commodities because of

the fixed belief that many manufacturers work off " seconds " on such customers. The

knowledge that they can at any time, when they so desire, call upon testing laboratories

to check the deliveries made to them on contracts based on specifications will induce a

large number of such purchasers to take full advantage of the specification method of

purchasing.

The outstanding fact in the specification situation at the present time is that a very

great majority of the purchasers who should be using specifications are not doing so. It

is to this great group of purchasers that the accompanying lists of laboratories will prove

most beneficial. If, in addition to obtaining copies of as good specifications as can be

written at the present time, all purchasers are able to secure lists of firms willing to manufacture to these specifications and to certify to compliance therewith, and lists of testing

laboratories and checking agencies, many of these purchasers will readily adopt the

specification method of buying. This is especially true of the purchasers of States and

municipalities who are anxious to use specifications, but have not thus far felt justified in

doing so because of inability to determine whether or not the commodities comply with

the specification requirements.

The application of the plan here outlined will mean that more manufacturers than

at present will be in need of testing and inspection services upon which to base such certifi- cates as they may be asked to issue to consumers buying upon nationally recognized

specifications. Moreover, to the extent that the application of the plan will result in the

use of specifications by purchasers not now buying on specifications, it will create a demand

for testing service on behalf of the buyers. In any event, numerous consumers will resort

to such tests as may be considered necessary or desirable to satisfy themselves that the

commodities do actually comply with the specifications. It seems evident, therefore*

that the widespread application of the plan must result in a greatly increased need for

testing service by both the producers and consumers. In the accompanying list of commercial testing laboratories the laboratories have

been arranged alphabetically in accordance with the geographical locations of the laboratories. Numerical references are used to indicate the types of commodities tested, and

alphabetical references indicate the nature of the tests. SYMBOLIC REFERENCES TO NATURE OF TESTS

COLLEGE RESEARCH LABORATORIES

It has seemed desirable to supplement the list of commercial testing laboratories with

a list of the laboratories in colleges. These laboratories are used not only for purposes of instruction, but also to a considerable extent for research work. In fact, many important

industrial research problems are being solved in the college laboratories.

The inclusion of a college laboratory in the accompanying list is to be interpreted

merely as showing that the laboratory is equipped to test the types of commodities indicated

for research and instructional purposes.

In almost all of the college laboratories a certain amount of commodity acceptance

testing is being done on either a commercial basis or for the purchasers of the States,

municipalities, public institutions, or the colleges themselves. However, there is a very

wide diversity in the methods of conducting such work with special reference to the

responsibility of the colleges for the tests made in the laboratories.

It is suggested that public purchasers and other persons interested in ascertaining

whether or not commodity acceptance testing will be undertaken by certain colleges, and

the conditions under which such testing will be carried on, communicate directly with

the proper officers of the colleges or with the individuals in charge of the laboratories.

In the accompanying list the laboratories have been arranged alphabetically in

accordance with the geographical location of the colleges. Explanations of the symbolic

references to the types of commodities that can be tested and the nature of the tests made are given on pages 1 and 2. GEOGRAPHICAL LISTING OF COLLEGES

FACILITATING THE USE OF SPECIFICATIONS

An analysis of the status of the making and the utilization of specifications reveals

the fact that many excellent specifications 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 great impetus to the popularizing of the use of specifications can be

given by eliminating this disadvantage to the small-quantity purchaser.

As a solution to the problem of eliminating the above-mentioned disadvantage and

thereby facilitating the use of specifications, use is being made of the so-called certifica- tion 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 willing

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 certification plan as effective as possible for " public purchasers,"

that is, purchasers for the Federal, State, and municipal governments who are spending

the money collected from the public in the form of taxes. There have already been compiled by the National Bureau of Standards 48 lists of such

firms as have expressed to the bureau (up to April 1, 1927) their desire to have their name

placed on the lists of manufacturers willing, when requested to do so, to certify to purchasers

that material supplied in accordance with the designated 48 United States Government

master specifications complies with the requirements and tests of these specifications and is so guaranteed by them. Copies of any of these lists of manufacturers, to which additions

are being made from time to time, can be obtained upon request. The specifications referred

to are as follows:

Organized for the purpose of securing economy in the procurement of material used by

the Government, the Federal Specifications Board makes a strenuous effort to adopt such

specifications as will cover commercial materials and supplies. Before the specifications are promulgated as official United States Government master specifications for the mandatory use of the departments and establishments of the Government, comments and criti- cisms from the manufacturers and interested engineering and technical societies are given

careful consideration. A list of the specifications thus far adopted by the board is given in

Bureau of Standards Circular No. 319, which can be obtained from the Superintendent of Documents, Government Printing Office, Washington, D. C, at 10 cents per copy.

Among the duties assigned to the board are not only the compilation and adoption of standard specifications for materials and services, but also the bringing of the Government

specifications into harmony with the best commercial practice whenever conditions permit,

bearing in mind the broadening of the field of supply.

Encouraging the maximum possible number of purchasing agents to make use of the

specifications of the Federal Specifications Board would broaden the field of supply by

inducing the maximum possible number of persons to manufacture commodities meeting the

requirements of the Federal Government. Moreover, the widespread use of specifications

of the Federal Specifications Board would serve to draw attention to such modifications

as might well be made therein in order to render them satisfactory to the buying public

and to bring them into harmony with the best commercial practice.

Reference is made herein specifically to United States Government master specifications as the lists referred to are those of manufacturers willing to certify to compliance with these

specifications. However, the plan outlined could readily be, and is being, applied to other

groups of nationally recognized specifications. It is to be expected that the application of

the plan will be of benefit not only in the general promotion of the use of specifications by

both the small and the large consumers, but also in the unification of specifications having

national recognition.

A DIRECTORY OF SPECIFICATIONS

Considerable economy can be realized in the purchase of commodities by the use of specifications.

Real competitive bidding can be invited, and the delivery of satisfactory material can be insisted upon. To an ever-increasing extent State and city governments, public utilities, and the better organized industries

of the country are adopting the use of specifications, which has been a feature of Federal Government

purchasing for many years. Information regarding the best known specifications for more than 6,000 commodities is given in convenient form in the National Directory of Commodity Specifications, which has been issued by the Bureau of Standards with the cooperation of the Bureau of Foreign and Domestic Commerce of the Department of Commerce. The book tells not only what specifications are in general use, but also by whom

they were prepared and where copies can be obtained. In it are conveniently indexed for ready finding

about 27,000 specifications prepared by the Federal Specifications Board and the separate departments

of the Federal Government, by State and city purchasing agents, public utilities, technical societies, and

trade associations.

# At the request of Secretary Hoover an advisory board was selected by these interests to represent them in supervising the preparation of the Directory.

The contents include: A statement and indorsement by the advisory board, a foreword by Secretary

Hoover, a thoroughly classified list of specifications for all types of commodities. There are also included an alphabetical list of commodities, which serves as an index to the specifications, and directions for obtaining copies of specifications listed in the Directory.

Whether you are a producer or a consumer, a seller or a buyer of commodities; whether you are inter- ested in the preparation or in the use of specifications, the Directory contains for you information which

you can not afford to do without. It is printed in small, but legible type, and thus the number of pages

has been kept at the minimum, 385, without sacrificing the usefulness of the Directory. It is bound in cloth.The cost of printing and binding the book at the Government Printing Office is $1.25.

DIRECTIONS FOR OBTAINING THE DIRECTORY OF SPECIFICATIONS

Copies of the National Directory of Commodity Specifications may be obtained from the Superin- tendent of Documents, Government Printing Office, Washington, D. C, by sending with the order a remit- tance either in the form of post-office money order, coupons (issued for the specific purpose of purchasing

Government publications), express money order, New York draft, or cash—at the sender's own risk. It is important to follow these directions explicitly to avoid delay and confusion. If the Directory is to be shipped to a foreign country (other than Mexico and Canada) , add one-third to the price, making the

total $1.67.
