1.1 This test method defines a method and measurement criteria to quantify the performance of a stationary skimmer in ideal conditions in support of a device’s nameplate recovery rate (capacity). If a determination of a skimmer’s capabilities in realistic conditions (that is, advancing or waves) is required, testing should be performed according to Guide or equivalent.
1.2 This test method includes the option of testing to determine recovery efficiency.
1.3 This test method and parameters are intended to provide ideal recovery conditions allowing the skimmer system to operate and collect oil at its maximum possible recovery rate. Given ideal conditions, inherent mechanical and physical attributes of the system become the limiting factors.
1.4 This test method is intended to identify limitations of the skimmer system, such as performance of the skimming mechanism, the flow of oil within the skimmer and sump, the pump characteristics, and typical discharge head conditions.
1.5 It is accepted that the measured nameplate recovery rate as determined by this test method will not likely be achievable under actual conditions of a spill. The measured nameplate recovery rate should be used in conjunction with a de-rating factor to account for such issues as changing encounter rate, changes in other recovery conditions, changes in oil properties and slick thickness, number of daylight hours, operator downtime, less than ideal control of skimmer settings, and inclement weather.
1.6 This test method involves the use of specific test oils that may be considered hazardous materials. It is the responsibility of the user of this test method to procure and abide by necessary permits and regulations for the use and disposal of test oil.
1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
