DIN ISO 2859 - Part 1
The procedure of DIN ISO 2859 - Part 1 only applies to those test properties that have been allocated to a Test Property Set with the testing method of Counting (AQL).
The different setup pages are described in this section. Choose the 
icon, enter the setup page, and then choose the related link.
Allowed AQL Values
In the Allowed AQL Values page, the Acceptance Quality Level (AQL) values to be applied must be defined according to the requirements of the supplier and the receiver. The AQL logic is only to be used for component testing.
The values in this page are automatically transferred to the Sample Instruction Setup page.
Evaluation Levels
In the Evaluation Levels page, users can define the various evaluation levels that form the basis of the Sample Instruction Setup page.
Inspection Levels
By means of various inspection levels, the key letters for the sample size are allocated to a certain lot size (see Sample Size for Inspection Level). According to DIN ISO 2859 - Part 1, section 10.1 "Inspection Level", inspection level II must be used if nothing else has been specified.
Sample Size for Inspection Level
In the Sample Size/Inspection Level page, users can select the appropriate inspection level and then assign Key Letters for the sample size to the according lot size interval.
This page is accessed by choosing the Card action on the Inspection Levels page.
Sample Instruction for Evaluation Level
In the Sample Instruction Setups page, choose the View action to open the Sample Instruction Setup page for the selected Evaluation Level.
The fields on the Lines FastTab are described in the following table.
| Field | Description |
|---|---|
| Key Letter | Manual setup of the key letter for the sample size from the Sample Size/Inspection Level page. |
| Sample Size | Based on the AQL Values and the Key Letter for the sample size, the sample size must be gathered from the Sample Instruction of DIN ISO 2859 - Part 1. |
| AQL Values | Based on the values specified in the Allowed AQL Values page. |
The values in the matrix display the maximum allowable acceptance limits depending on the sample size and the defined AQL Values. Thus, the allowable acceptance number indicates how many error parts the sample is allowed to contain so that the tested quantity (= shipped quantity) is still accepted.
Inspection Severities
The switching rules between the various evaluation levels of items to be tested (simultaneously considering the vendor) are defined in the Inspection Severity page.
The Inspection Severities page displays all existing inspection severities. To open the Inspection Severity page, select the relevant line and then choose the Edit or View action on the Manage menu.
The respective current evaluation level / test number of an upcoming test order for an item is entered into the Test Status page (Item Card > Quality Assurance > Test Status) based on the result of the test order and the determined value of this page.
The fields in this page are described in the following table.
| Field | Description |
|---|---|
| Current Test Type | The current evaluation level (linked to the Current Test No.) that the item is tested with in the test order. |
| Current Test No. | The current test number which specifies the Current Test Type. |
| Next Test Type when OK | Indicates the next evaluation level (in connection with the next test number) if the testing has been classified as OK. |
| Next Test No. when OK | Indicates the next test number (in connection with the next evaluation level) if the testing has been classified as OK. |
| Next Test Type when not OK | Indicates the next evaluation level (in connection with the next test number) if the testing has not been classified as OK. |
| Next Test No. when not OK | Indicates the next test number (in connection with the next evaluation level) if the testing has not been classified as OK. |
| Description | Description of the respective line. |
| Default | If an item has not been tested yet, the evaluation level with this checkbox selected is automatically used (usually, this is the Normal 1 inspection type). |
| No Testing | If selected, the testing of the related line will be skipped (Skip-Lot-Logic) and no test order will be created automatically. |
