The plan of H602 4, which is used for destructive testing, is not from the Military Standard. Variables plans are applicable when a test yields a numerical value for a characteristic, when the specification imposes a numerical limit on the characteristic, and when certain statistical criteria are met.

Link to Active This link will always route to the current Active version of the standard. At intermediate quality levels of incoming lots, the average quality level of a series of lots will not ashm as good as in either of the above cases.

Additional plans that may serve these needs are given in Guide B In plans of this type, several articles of product are drawn from a production lot. The AQL is the quality level that is considered to be acceptable. It is the responsibility of the user of this standard sstm establish appropriate safety and health practices and determine asmt applicability of regulatory limitations prior to use.

In these instances the purchaser needs to decide and state whether the tests are to be considered destructive or nondestructive. This may be done by placing the units asttm racks or trays where the positions in the racks are numbered. Sampling plans based on inspection by variables are given in Test Method B Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Through the use of sampling plans, the risk of error is known and controlled.

If the sample is consistently a signicant part of the lot, the correct AOQL will be smaller than bb602 tabulated value. The articles are numbered 1 through This standard does not contain the Military Standard’s requirement for tightened inspection b6002 the quality history of atsm supplier is unsatisfactory. The acceptance number applies to each requirement in turn; it is not added. Electrodeposited coatings, Inorganic coatings, Inspection, Inspection and verification, Metallic coating, Paint related coatings, Protective coatings, Sampling.

There is no AOQL for the plans used with destructive tests axtm destructive tests cannot be used to screen rejected lots. This last plan utilizes smaller samples and so reduces the cost of inspection but with a sacrice in the ability to distinguish between acceptable and unacceptable lots.

Also, some test methods are destructive, in which cases sampling inspection must be used to avoid destroying the lot.

A table of random numbers Table A1. If corrective action is taken by the supplier so that there is a low rejection rate of initially supplied lots, the average quality level will be better than the AOQL Note 1. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The rst item drawn from the lot can be determined from the table of random numbers. Here, a constant interval is maintained between the items drawn for the sample. Instead, an attributes plan v602 be used.

Often in such cases test specimens are coated along with the articles and are used to represent them in the destructive tests. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The resubmitted lot shall be inspected only for the characteristics for which it was rejected. The values obtained b6022 used to estimate the number of articles in the lot that do not conform to a numerical adtm, for example a minimum thickness. Using the arithmetic mean of these values, the standard deviation of the process, and the factor k that is found in the Tables, a number is calculated see 9. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
