The inspection set forth in this document shall become a part of the contractors overall inspection system or quality program. absence uf any inspection requirements in the document shall not relieve the contractor of the responsibility of assuring that all products or supplies submitted to the
35、Government for acceptance comply with all requirements of the contract. Sampling in quality conformance does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to acceptance of defective material. The 4.2 Classification of inspection.
36、The inspection requirements specified herein are classified as follows: a. b. Quality conformance inspection (see 4.4).

The slope of grain may be determined by combining the grain direction of two adjacent faces of a square or rectangular piece. When one of these faces is straight gr
47、ained, the true slope of grain is shown on the other face. When there is a slope on both faces, the true or combined slope is greater-than the slope on either face. Slope of grain is shown on edge grained faces by the summer wood bands, by the direction in which a free flowing ink or dye spreads, or
48、 by the course taken by a narrow strip lifted by a knife point and torn out. Direction of fiber may also be measured by a slope of grain detector. Any size 1 pin, size 2 pin, or square or rectangular blank of the size 3 pin (see 4.4.2.1) having a slope of wood grain exceeding 1-inch in 10 inches sha
49、ll be classified as defective. 12 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-P-233H 3 = 9999706 0373043 2 MIL-P-2383H 5.
