1 Scope

This section GB/T 31971 specifies the skimmers quantitative performance data in the case of high-viscosity oil recovery method for determining, in order to use Households objective judgment, comparison and evaluation of different types of skimmers design and performance. The method of this Part shall apply to and need to be in the sink To control the oil slick and test characteristics. This section applies to the size of the sink in the test range of all types of skimmers. Test procedures specified in the provisions of this section control bar Lower member provides comprehensive test results to the device under test, applied to one or more high-viscosity oil. For the dedicated/embedded systems, test procedures prescribed in this section apply only to meet the test criteria skimming device, not suitable for Whole skimmer system.
