The

12、 initial certificate submitted shall be substantiated by evidence of the agents authority to bind his principal. Substantiation of the agents authority will not be required with subsequent certificates unless, during the course of the contract, this authority is vested in another agent of the certif

13、ying organization, 4.1.2 Government verification.-Using the contractors written quality assurance procedure, this detailed specification, the applicable drawings and other contractual documents as a guide, the Government inspector shall verify at unscheduled intervals, all quality assurance operatio

14、ns performed by the contractor. Verification shall be performed to the extent necessary to assure compliance with the contractual requirements, Severity of Government inspection of individual characteristics will be directly related to the seriousness of the classification assigned. In no instance w

15、ill a characteristic classified “critical“ be accepted solely on the basis of the contractors records. 4.2 Inspection provisions. 4.2.1 Lot formation. -The term “lot“ as used throughout this specification refers to an inspection lot, which is defined as an essentially homogeneous collection of units

16、 of product from which a representative sample is drawn and inspected to determine conformance of the lot with applicable requirements. The sample selected shall represent only that quantity of units from which the sample was drawn and shall not be construed to represent any prior or subsequent quan

17、tities presented for inspection. Homogeneity shall be considered to exist provided the lot has been produced by one manufacturer, in one unchanged process using the same materials and methods, in accordance with the same drawings, same drawing revisions, same specifications and same specification re

18、visions. Changes to the process, specifications, or drawings, not affecting safety, performance, inberchangeability, or storage, as determined by the Government, shall not be deemed to alter the homogeneity of the lot. In- spection lots shall comply with MIL-STD-105. Unless otherwise approved by the

19、 contracting officer, the inspection lot size of end items deliverable under the contract shall be not less than the smallest weekly estimate of quantities contractually scheduled for production during the contract period nor more than the largest monthly quantity contractually scheduled for deliver

20、y during the contract period. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-HC v) Ma, Id *oa HkE HC cd k rn a da, CG Ud rl k OE o rncd a, rl aE EO cdFi vlk rn aa, oc kd rl k OC o rncd H Cu0 Hri aE 2 5: m vlbi 4 E a, rl .P Ji, a, xa, G Ed Od k kA

Dissolve the sample in the acetone by

24、 stirring with a stirring rod. pour the residue in the beaker into a tared 50 ml. fritted glass crucible and aspirate with air. Dry the crucible in an oven at 100 t 5 degrees C for one hour. Remove the crucible from the oven and place in a desiccator to cool. After the crucible 1s cool, weigh the cr

25、ucible and contents and record the weight. Place the crucible and its contents on an aspirating assembly. While aspirating, pour hot water into the crucible until all the ammonium nitrate is dissolved. Then place the crucible and its contents into an oven at 100 t 5 degrees C for one hour. Remove th

26、e crucible from the oven andplace in a desiccator to cool. Remove from the desiccator and weigh the crucible with its contents and record the weight. as the percent ammonium nitrate. Calculate the gain in crucible weight as the percent of aluminum. aluminum and ammonium nitrate and subtract from tot

The overall specific gravity of the charge in each samgle

29、 bomb shall be determined as follows: Weigh each sample bomb empty. Fill each sample bomb with water and weigh, making allowance for the weight of the water displaced by the components (e.g., auxiliary booster sleeve, auxiliary booster, adapter-booster) which are added during the loading. Empty each
