(a) Individual load cells or load cell systems must be accompanied by readout or indicating equipment and all associated cables and fixtures. (b) For the fee quoted, calibration will be made on one machine with up to 10 incremental loads applied consecutively without return to zero load. For each load in excess of 10, an additional fee equal to onetenth of the applicable fee will be charged. For any device requiring the use of more than one machine, a charge will be made covering the cost of the additional work involved. (c) When devices submitted are found to be unsuitable for test or unreliable, the test may be discontinued and a charge will be made to cover the cost of the work done. 213.042g Capacity exceeding 112,000 pounds but not exceeding 300,000 pounds: Compression. 213.042h Tension. 213.042i Tension and compression. 13.042j Capacity exceeding 300,000 pounds but not exceeding 1,000,000 pounds: Compression.

(b) The charge for special mechanical tests is made on the basis f the hours of service furnished by members of the staff. (c) The time shall be computed as the number of official working ours from the time the members of the staff leave the Bureau until they eturn to it plus any overtime spent on the tests. (d) Where tests require travel outside the limits of 30 miles rom the Bureau, transportation and subsistence charges will be added to he service charge. 13.043a Service of a member of the staff of grade GS-9, 13.043b grade, per hour. or any higher Service of a member of the staff of grades below GS-9, per hour. 213.044 Proving rings. (a) These fees apply to calibration or recalibration of proving suitable for use as laboratory or transfer standards in accordance th Sections I, II, III, and IV of the Appendix of NBS Circular 454.* ngs BS Circular 454, Proving Rings for Calibrating Testing Machines. See NBS Handbook 77, Precision Measurement and Calibration, Vol. II, Heat d Mechanics, p. 573. so ith up to 10 independent loads for compression or tension applied. Fees for complete calibrations apply to rings submitted for initial calibration. For each load in excess of 10, an additional fee equal to one-tenth of the applicable fee for complete calibration or recalibration will be charged. For any device requiring the use of two or more machines, a charge will be nade covering the cost of the additional work involved. (c) When devices submitted are found to be unsuitable for test or unreliable, a test may be discontinued and a charge will be made to cover the cost of the work done.
