1.1 This guide defines a procedure and measurement criteria to quantify the recovery rate and efficiency of a stationary skimmer system in drift ice conditions.

1.2 The suggested procedure and test parameters are intended to provide conditions typical of relatively sparse drift ice and relatively dense drift ice coverage.

1.3 It is accepted that the recovery rate as determined by this guide will not likely be achievable under actual conditions of a spill. The procedure in this guide does not account for such issues as changing recovery conditions, number of daylight hours, operator downtime, less than ideal control of skimmer settings, and inclement weather.

1.4 The procedure in this guide involves the use of specific test oils that may be considered hazardous materials. It is the responsibility of the user of this guide to procure and abide by necessary permits and regulations for the use and disposal of test oil.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This guide establishes test conditions that will provide a measured oil recovery rate and efficiency for a skimmer operating in drift ice.

4.2 End users need a procedure to quantify optimum performance data for planning and selection of equipment.

4.3 The procedure in this guide will assist in verifying and accurately reporting skimmer system performance.

4.4 Tests will be conducted under well documented conditions and provide repeatable results. Other detailed testing and collection of skimmer performance data are covered under existing standards (see Guide F631 and Test Method F2709).
