by taking the difference between the actual measured dimension and the standard dimension. The error is an error in excess and is to be preceded by a plus sign when the measured dimension is greater than the standard dimension. The error is an error in deficiency and is to be preceded by a minus sign when the measured dimension is less than the standard dimension,

(a) The standard dimensions of a barrel for fruits, vegetables, and other dry commodities other than cranberries, and of a barrel for cranberries, with which the actual measured dimensions are to be compared, are as follows:

application. For the purpose of the application of tolerances, barrels for fruits, vegetables, and other dry commodities other than cranberries, are hereby divided into two classes as follows:

(a) Class 1 shall include (1) all barrels no dimension of which is in error by more than the following amounts, and (2) all barrels one or more of the dimensions of which are in error by more than the following amounts, and which in addition have no dimension in error in the opposite direction:

Error,

14 Distance between heads----

% Circumference of bulge, outside measurement.

142 (b) Class 2 shall include all barrels at least one dimension of which is in error by more than the amounts given above, but which in addition have at least one dimension in error in the opposite direction. (This class includes all barrels mentioned in section 1 of the law in the proyiso reading: "Provided, That any barrel of a different form having a pacity of seven thousand and fifty-six cubic inches shall be a standard barrel.") (Sec. 1, 38 Stat. 1186; 15 U.S.C. 234) § 241.7 Tolerances to be allowed.

(a) The tolerances to be allowed in excess or in deficiency on the dimensions of all barrels of Class 1 shall be as follows:

Tolerance

inches Diameter of head...

44 Effective diameter of head..

14 Distance between heads..

44 Circumference of bulge, outside measurement.

142 Length of stave..

% (1) If no dimension of a barrel of Class 1 is in error by more than the tolerance given above, then the barrel is within the tolerance allowed.

(2) If one or more of the dimensions of a barrel of Class 1 is in error by more than the tolerance given above, then the barrel is not within the tolerance allowed.

(b) The tolerance to be allowed in excess or in deficiency on all barrels of Class 2 shall be 11/2 inches (1.5) inches, and this tolerance is to be applied to the result obtained by the application of the following rule:

[merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][ocr errors][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small]

(1) Having determined the errors of each dimension and given to each its proper sign (see § 241.4), add the errors on the effective diameter of head and the distance between heads algebraically and multiply the result by 1.67 (or 5/3). Then add this result to the error on the circumference of bulge algebraically. If the result obtained is not greater than the tolerance given above, then the barrel is within the tolerance allowed; if the result is greater than this tolerance, then the barrel is not within the tolerance allowed.

NOTE: To find the algebraic sum of a num. ber of quantities having different signs, first add all those having one sign; then add all those having the opposite sign; then subtract the smaller sum from the larger, giving this result the sign of the larger quantity.

(c) The tolerance to be allowed in excess or in deficiency on the dimensions of all barrels for cranberries shall be as follows:

Tolerance,

% (1) If no dimension of a barrel for cranberries is in error by more than the tolerance given above, then the barrel is within the tolerance allowed.

(2) If one or more of the dimensions of a barrel for cranberries is in error by more than the tolerance given above,

then the barrel is not within the tolerance allowed.

(d) The tolerances to be allowed in excess or in deficiency on all subdivisions of the standard barrel for fruits, vegetables, and other dry commodities other than cranberries, and on all subdivisions of the standard barrel for cranberries, shall be the values given in the following table, and these tolerances are to be applied to the result obtained by the application of the following rule:

(1) Having determined the errors on each dimension and given to each its proper sign (see § 241.5), add the errors on the effective diameter of head and the distance between heads algebraically and multiply the result by 1.67 (or 53). Then add this result to the error on the circumference of bulge algebraically. If the result obtained is not greater than the tolerance given in the following table for the proper subdivision, then the barrel is within the tolerance allowed; if the result is greater than this tolerance, then the barrel is not within the tolerance allowed.

SOURCE: The provisions of this Part 256 appear at 32 F.R. 10252, July 12, 1967, unless otherwise noted. $ 256.1 Introduction.

This Part states policies and procedures concerning the Research Associate Program at the National Bureau of Standards. In the exercise of its functions as a major scientific agency of the Federal Government, the National Bureau of Standards may make its facilities available to persons other than Bureau employees to work with NBS scientists and engineers in collaborative research aimed at furthering the Nation's scientific, industrial, and economic growth. Such cooperative programs may be sponsöred by professional, technical, or industrial organizations or associations. Such participants, when so sponsored, are designated "Research Associates". 8 256.2 The Research Associate Program.

The Bureau provides its facilities, scientific competence, and technical supervision for defined scientific or technical research by a Research Associate when such research is complementary to and compatible with scientific or technical research being performed or to be undertaken by NBS under its statutory mission and authority. The Sponsors pay the salaries of their Research Associates and Sponsor-furnished technical assistants and secretaries of the Research Associates, if any, their travel costs, and other related expenses. Additionally, Sponsors reimburse NBS for the cost of research equipment, services, or materials obtained for the Research Associate.

Beginning in the third year of continued sponsorship, Sponsors also reimburse the Bureau for other costs such as, supervision and administrative expenses at a rate comparable to the cost experienced for NBS employees for similar services. § 256.3 Procedure.

Arrangements for collaborative research by NBS with a Research Associate generally begin through discussions or correspondence between NBS scientists and representatives of potential sponsoring companies, trade associations or professional organizations. These preliminary steps are followed by the consummation of

Memorandum of Agreement which is signed by NBS, the sponsoring organization and the Research Associate. The agreement sets out the respective responsibilities and obligations of all parties. § 256.4 Qualifications.

Each candidate selected to serve as a Research Associate must be determined to be scientifically qualified by the Sponsor and by the NBS, and found by NBS to be of good moral character and to possess suitable personal qualities. § 256.5 Duration of projects.

The work of a Research Associate is generally conducted on a full-time basis. Typically, Research Associates are in residence at NBS for 6 to 18 months; longer-term programs may be carried on by a succession of Research Associates. Agreements provide for cancellation by any of the parties. $ 256.6 Information concerning the Re

search Associate Program. Information concerning the Research Associate Program may be obtained from the Office of Industrial Services, National Bureau of Standards, Washington, D.C. 20234.
