测量航空燃料中燃料系统防冻剂(乙醚型)的试验方法

Standard Test Method for Measurement of Fuel System Icing Inhibitors (Ether Type) in Aviation Fuels

适用范围:<p>DiEGME is miscible with water and can be readily extracted from the fuel by contact with water during shipping and in storage. Methods are therefore needed to check the additive content in the fuel to ensure proper additive concentration in the aircraft.</p> <p>This test method is applicable to analyses performed in the field or in a laboratory.</p><p id="s00002">1.1 This test method covers a technique for measuring the concentration of Diethylene Glycol Monomethyl Ether (DiEGME) in aviation fuels. A measured volume of fuel, extracted with a fixed ratio of water, is tested with a suitable refractometer to determine the concentration of fuel system icing inhibitor (FSII) in fuel. Precision estimates have been determined for the DiEGME additive using specific extraction ratios with a wide variety of fuel types. The extraction ratios are high enough that portable handheld refractometers can be used, but not so high as to sacrifice accuracy or linearity, or both, in the 0.01 to 0.25 vol % range of interest.</p> <p id="s00064">1.2 DiEGME is fully described in Specification <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?D4171-HTML">D4171</a> and in other specifications.</p> <p id="s00003">1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.</p> <p id="s00004">1.4 <span class="italic">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. </span>
