ASTM F3367-21a

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F3367 − 21 F3367 − 21a
Standard Practice for
Simplified Methods for Addressing High-Intensity Radiated
1
Fields (HIRF) and Indirect Effects of Lightning on Aircraft
This standard is issued under the fixed designation F3367; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers simplified methods for addressing High-Intensity Radiated Fields (HIRF) and the Indirect Effects of
Lightning (IEL) on aircraft. The material was developed through open consensus of international experts in general aviation. This
information was created by focusing on Aircraft Certification Level 1, Level 2, and Level 3 Normal Category aeroplanes. The
content may be more broadly applicable. It is the responsibility of the applicant to substantiate broader applicability as a specific
means of compliance. The topics covered within this practice are: Overview; Minimum Design Requirements; Aeroplane
Assessment Level; HIRF and IEL Safety Analysis; HIRF Compliance; IEL Compliance.
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 CAA) concerning the acceptable use and
application thereof. For information on which oversight authorities have accepted this practice (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 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this
standard.
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.
2. Referenced Documents
2.1 Following is a list of external standards referenced throughout this practice; the earliest revision acceptable for use is indicated.
In all cases, later document revisions are acceptable if shown to be equivalent to the listed revision, or if otherwise formally
accepted by the governing civil aviation authority; earlier revisions are not acceptable.
