ASTM F3397/F3397M-21

4.1?This specification provides designers of general aviation aeroplanes a process for evaluating and testing a fuel system under hot weather conditions to ensure safety during flight. The specification is applicable to kerosene-type turbine engine fuels and fuel systems for traditional general aviation aeroplanes.

1.1?This standard practice provides requirements for performing hot weather testing as a means of compliance to Subsection 7.7 of Specification F3063/F3063M for kerosene-type turbine fuels such as Jet A and Jet A-1 (Specification D1655). The appendix provides supplemental information and considerations for turbine fuel system hot weather operation. The material was developed through open consensus of international experts in general aviation.

1.2?An applicant intending to propose this information as Means of Compliance for a design approval must seek guidance from their respective oversight authority (for example, published guidance from applicable civil aviation authorities (CAAs)) concerning the acceptable use and application thereof. For information on which oversight authorities have accepted this standard (in whole or in part) as an acceptable Means of Compliance to their regulatory requirements hereinafter (the Rules), refer to the ASTM Committee F44 web page (www.astm.org/COMMITTEE/F44.htm).

1.3?The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.4?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. 1.5?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.
