A test in which solutions and test organisms are placed in chambers for the duration of the test is referred to as a static test. In a static test, the conditions of the test, such as the test solution and the organisms, remain constant over time. This means that the water or solution does not flow or change throughout the test period, allowing for observation and measurement of the effects of the substance being tested on the organisms in a fixed environment.

Static tests are often used to assess the toxicity, behavior, or effects of pollutants or other chemicals on aquatic organisms. By keeping the conditions stable, researchers can gather reliable data on how the organisms respond to the test substance over the course of the experiment, without any variable influences from changing water chemistry.

Other types of tests, such as flow-through tests or dynamic tests, involve continuous influx or changes in the test environment, which can lead to different results. In contrast, the static test's controlled environment is crucial for accurately assessing the impact of specific variables on the test organisms.
