§ 241.6 Classes of barrels for tolerance 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:

Effective diameter of head..
Distance between heads___
Circumference of bulge, outside meas-

urement.--.

Error,

inches

(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 proviso reading: "Provided, That any barrel of a different form having a capacity 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:

[blocks in formation]

(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%). 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.

(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 5%). 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.

§ 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 sponsored by professional, technical, or industrial organizations or associations. Such participants, when so sponsored, are designated "Research Associates". § 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.

Sec.

260.1

Definitions.

260.2 Scope and application. General requirements.

260.3

260.4 Detailed requirements.

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 a 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.

§ 260.2

Scope and application.

This standard shall apply to devices furnished with household refrigerators manufactured and introduced or delivered for introduction into interstate commerce after the effective date which enable such refrigerators to be opened from the inside. The requirements of this standard shall apply to household refrigerators in their normal operating position only. The releasing feature(s) of the device shall be accessible from all spaces which (a) are bounded by interior walls or shelving, (b) are directly accessible when the exterior hinged door(s) is (are) opened, and (c) have a minimum dimension of 8 inches or more and a volume of two cubic feet or more either with all shelving in place or as the result of the removal or the rearrangement of any or all of the shelving. § 260.3 General requirements.

§ 260.4

Detailed requirements.

(a) Releasing forces. As determined by the tests called for in § 260.5, the device (1) shall permit the refrigerator door to be opened on the application of a force equivalent to one which, if directed perpendicularly to the plane of the door and applied anywhere along the latch edge of the inside of the closed door, shall not exceed 15 pounds, (2) shall permit the refrigerator door to be opened on the application of clockwise or counterclockwise turning moment of not more than 5 in.-lb. to a knob on the door through an angle of rotation of 45° (±15°) in either direction, or (3) shall function automatically to permit the door to be opened with a force of 15 pounds or less applied as described in subparagraph (1) of this paragraph whenever space(s) exist or is (are) created with dimensions and volumes. exceeding the dimensions and volumes. imposed by § 260.2.

and (b) Description location of knob(s). The knob (s) shall resemble a conventional doorknob in shape and size, and shall be mounted near the latch side of the door extending into the cabinet at least 4 inch beyond any inner door surface within a six-inch radius of the knob center. The knob(s) shall be mounted in such a manner that there is a minimum of 3/4 inch clearance between the inner periphery of the knob(s) and adjacent inner door surfaces. The knob(s) shall be located so as to provide the accessibility required by § 260.2.

(c) Wear. The device shall comply with the requirements of paragraph (a) of this section after 300,000 cycles of operation of the door as determined by the tests called for in § 260.5.

(d) Protection against adverse effects from spillage, cleaning, defrosting, and condensation. Devices shall be designed so that spillage of foods or beverages, cleaning or defrosting in accordance with manufacturer's recommendations, or normal condensation will not so adversely affect the operation of the device as to result in its failure to meet the requirements of paragraph (a) of this section, as determined by the tests called for in § 260.5.

Household refrigerators shall be equipped with a device enabling the doors thereof to be opened easily from the inside, either by the application of an outwardly directed force to the inside of
