ASTM F2534-17R22

1.1 This guide provides information and criteria for estimating the thickness of oil on water using only visual clues.

1.2 This guide applies to oil-on-water and does not pertain to oil on land or other surfaces.

1.3 This guide is generally applicable for all types of crude oils and most petroleum products, under a variety of marine or fresh water conditions.

1.4 The thickness values obtained using this guide are at best estimates because the appearance of oil on water may be affected by a number of factors including oil type, sea state, visibility conditions, view angle, and weather.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.
