Pump or pump unit: behavior check

Two types of tests can be carried out to verify the performance of a pump or pump unit: acceptance tests or development tests.

In acceptance testing, the aim is to check the quality of the product, both in terms of compliance with contractual requirements vis-à-vis a particular customer (acceptance testing), and in terms of methods decided by the company (e.g., in compliance with ISO 9000) to facilitate general external recognition of the quality of its products. In such cases, reference to standards and the use of acceptance criteria and methods recognized outside the company are essential.

In the case of development testing, verification is part of the product development process, and may take place during the product's development (for example, on a model or prototype). In such cases, the manufacturer is generally the only one to decide on the course of action to be taken, and reference to standards is not a necessity.

This article deals with acceptance testing, although certain methods can be used in both cases.
