The permission to use asgm specimens and the requirements covering them and their use should be set forth in the applicable coating specication, purchase order, or other governing document. Find Similar Items This product falls into the following categories. The larger the proportion of nonconforming articles in an inspection lot, the more likely it will be that the sample will indicate that the lot is unacceptable.
A sampling plan is selected that has a high probability of accepting ast, of AQL quality and of rejecting lots of LQL quality.

If the pencil falls on column 10, line 11, and the coin is tails, the decision is to read down the column until 13 numbers are chosen. Worldwide Standards We can source any standard from anywhere in the world. There may be instances in which tighter or looser plans or ones that are more discriminating are desired.
Link to Active This link will always route to the current Active version of the standard. 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 correct values are obtained by multiplying the tabulated values by: Active view current version of standard. A characteristic of the coating on the drawn articles is measured. Throughout this method, it is assumed that no mistakes are made in sampling, measurement, and calculation. Additional plans that may serve these needs are given in Guide B Historical Version s – view previous versions of standard.
This may be done by placing the units in b60 or trays where the positions in the racks are numbered. Your basket is empty.
An alternative is rectifying inspection in which rejected lots are screened and used.
B62 superscript epsilon e indicates an editorial change since the last aatm or reapproval. If the test method to be used is nondestructive, the sample size shall be that directed in 8. Other tests can destroy the coating in nonessential locations, in which case the item can still be functional. For this reason, there are no AQL, etc. The larger the sample, the smaller this risk, but, the larger the cost of inspection.
When a test is neither clearly nondestructive nor destructive see Note 2, 8. Therefore, basic to any sampling inspection plan is the willingness of the buyer to accept lots that contain some nonconforming articles.
It is the worst condition that can occur under rectifying inspection. There may be instances in which tighter or looser plans or ones that are more discriminating are desired.
Through the use of sampling plans, the risk of error is known and controlled.

Last previous edition approved in as B — 88 If every article in an inspection lot conforms to its requirements, every article in the sample will conform also. These are explained in Test Method B Bias can be avoided by numbering the articles, randomly selecting a group of numbers equal to the sample size, and inspecting the articles with the selected numbers.
Current edition approved May 15, For this reason, there are no AQL, etc. The articles are numbered 1 through If it is less, the lot does not conform. When the incoming lots are of a good quality level, the average quality level of a series of lots will be even better when the rejected lots are screened and resubmitted.
If the units have serial numbers, the serial numbers can be used. The values obtained are used to estimate the number of articles in the lot that do not conform to a numerical limit, for example a minimum thickness.

The plan of Table 4which is used for destructive testing, is not from the Military Standard. Starting at this point, a coin is tossed to decide whether to go up or down the column; heads, up; tails, down. The constant interval is 24 divided by The fourth plan is intended to be used when the inspection methods are destructive.
At intermediate quality levels of asstm lots, the average quality level of a series of lots will not be as good asgm in either of the above cases. Accept and continue Learn more about the cookies we use and how to change your settings.
