Summary: This Standard specifies the skimmers to quantitatively determine the performance data under dynamic conditions of the process water, so that end users can objectively judge, compare and evaluate different types of skimming device design and performance. This method is suitable for testing in the sink and the control requirements specified characteristics and properties of the oil slick. This Standard applies to the size of the equipment in the test water plant size to limit the scope of the various types of skimmers. Under controlled conditions, this test procedure provides a full range of results for the device under test and one or more oil.

1 Scope

GB/T 31971 This section provides skimmers quantitative performance data to determine water under dynamic conditions of the process, so that end users can Objective evaluation, compare and evaluate different types of skimming device design and performance. This method is suitable for testing in the sink and the provisions of the oil Control characteristics and properties of the oil slick requirements. This section applies to the size of the device in the test tank size to limit the scope of the various types of skimmers. Under controlled conditions, this test procedure Were tested device and one or more oil provides a full range of test results. NOTE. When using these test results are used to predict the skimmers performance under actual operating conditions need to be cautious.
