Unless otherwise specified in the contract or purchase order, the supplier is responsible for the performance of all inspection require* eKtS as specified herein. Except as otherwise specified, the supplier may utilize his own facilities or any commercial laboratory acceptable to the Government, The Government reserves the right to perform any of the inspections set forth in the specification where such inspections arc deemed necessary to assure supplies and services conform to prescribed requirements. f*2 Sampling for quality conformance Inspection. Sampling for quality conformance in spection shall be poriormea in accordance with the provisions set forth in MIL-STD-105, ex cept where otherwise indicated hereinafter. For purposes of sampling, an inspection lot for Inspection and tests shall consist of all material offered for delivery at one time. -2.1 Examination of filled containers. A random sample of filled containers shall be taken from each lot in accordance with MIL-STD-105 at Inspection Level I and acceptable quality level 4.0 percent defective to verify compliance with requirements regarding fill Closure, marking and all other requirements not Involving tests. Containers shall be e x amined for defects of construction of the container and the closure, for evidence of leakage, and for unsatisfactory markings; each sample filled container shall also be weighed to determine the amount of contents. Any container in the sample, having one or more defects, or under required fill, shall not be offered for delivery. If the number of defective containers in any sample exceeds the acceptance number for the appropriate sampling plan of MIL-STD-1U5, this shall be cause for rejection of the lot represented by the sample. 4.2.2 Testing. From each inspection lot, sample containers shall be selected st ran dom, as follows, Tor the tests specified in 4.3, Lot 5izc 15 or loss 16 to 30U 301 to 800 801 and over Sample Site --T 2 3 4 There shall he no evidence of failure to meet tho specified requirements. 4.2.2.1 Thermal conductivity. The test of 4.3.9 need only be conducted for one of the following reasons: 2 J V. HH.-C- Il'ilD (n) If, within five years preceding the dnte of invitation for bids, the cement lias net been `tested by an acceptable testing laboratory and found in Compliance with tlie. requirementr. of 3.3. (b) If the cement offered for delivery is not the same in all respects as that previously tested. 4,S Test procedures. <3,1 Sulfur content. The sulfur content shall bo determined by cither the conhustic or evolution method. 4.3.1 W ntcr-ceacnt ratio for proper troweling consistency. A weighed quantity of dry cement shall qc" mixed'wt tii a weighed quantity of "water to determine the water cement ratio for satisfactory troweling consistency. For tests to determine compliance with this Specification the water-cement ratio shall lie that which (tires the measured eon;.i it-i.cy of 3$ to 45 percent by Method A, or 7 to 9 inches by Method h when *ietermini'! by the hrniTiliirr outlined in ASTM-C 405. 4.3.3 Cnverngo 1:111111 ity ami vo Ilimatrie shrinkurn.
