What does ATP stand for?
| Full form | Acceptance Test Procedure |
|---|---|
| Category | Science & engineering |
| Type | Initialism |
The initialism ATP stands for Acceptance Test Procedure in engineering test documents. In this usage it identifies the procedure used to carry out an acceptance test.
NASA’s historical glossary records this expansion, and a 1999 NASA report identifies a particular ATP procedure by document number. A procedure specifies how a check is carried out; the recorded result describes what happened. The same letters can also mean Acceptance Test Plan, so keep the full document title and identifier rather than inferring its role from ATP alone.
Meaning in context
- Acceptance Test
- The testing context in this document name, not a statement that acceptance has already occurred.
- Procedure
- The instructions for carrying out the check, rather than its recorded outcome.
Practical examples
Separate instructions from evidence
- Before
We have the ATP file, so the display test passed.
- After
The procedure describes the check; a separate execution record is needed to show the observed result.
Having instructions establishes neither execution nor outcome. This original example uses a simple display check rather than the source report’s engineering equipment.
State the observation
- Before
The display should show READY, therefore it did.
- After
Expected display: READY. Observed display: WAIT. Record the difference before assessing the criterion.
Expected and observed values are distinct fields. A mismatch must not be rewritten as the expected result.
Original illustrative examples, not quotations or reports of actual events.
Use ATP with clarity
Does an ATP procedure document show that the test was actually performed and passed?
See all guidance
Identify the document
Expand the letters using the document’s own title.
Acceptance Test Procedure, with its identifier and revision.
Read the steps
Separate the action and expected observation.
Which action is followed by which expected display?
Read the result
Look for the actual execution record and observed outcome.
The procedure file is not the result record.
This compares two entered observations. It runs no test, creates no official record and decides no engineering acceptance.
