This data can be used to create many different chart systems, including percent charts, charts showcasing the number of affected units, count-per-unit charts, demerit charts, and quality score charts. The procedures and structure of ANSI/ASQ Z1.9 are essentially the same as for MIL-STD-414. This inspection method is generally used for two purposes: The most widely used standard for attributes sampling plans is ANSI/ASQ Z1.4, but this standard can also be used as the first approach. For the quality level of 1.5% defective, the average total number of pens inspected per lot is 266.2. For example, if out of a sample taken from a lot a predefined number of bullets fire, the lot is accepted otherwise rejected. Using the methods above, this sampling plan can be used to test for a single specification.
