4.6.1.3.1 Group B Sampling plan. Statistical sampling and inspection shall be performed on an inspection lot basis
with a random sample of components selected in accordance with table VI. Acceptance shall be based upon the
zero defective sampling plan. No failures shall be permitted. Sample sizes are for standard Military component
reliability and for higher level reliability (intended for space flight applications).
