ASTM F3005-22

Standard Specification for Batteries for Use in Small Unmanned Aircraft Systems (sUAS)

ABSTRACT
This standard specifies the requirements for batteries used in small Unmanned Aircraft Systems (sUAS). It covers the standard terminology for sUAS as well as the requirements with respect to cells, mechanical design and assembly, electrical design, and maintenance of the pack and the recording of maintenance data.
SCOPE
1.1 This standard defines the requirements for batteries used in small Unmanned Aircraft Systems (sUAS).  
1.2 This standard does not define requirements for the systems in which sUAS battery packs may be utilized.  
1.3 This standard is subordinate to Specification F2910.  
1.4 If allowed by a nation’s GAA, certain sUAS may be exempt from this standard and may use commercial off-the-shelf (COTS) batteries in non-safety-critical payloads (lithium chemistries may not be exempted). Air transport regulations still shall be adhered to when air transport is used for COTS cells or batteries in bulk.  
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.

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.

3. Terminology
3.1 Unique and Common Terminology—Terminology used in multiple standards is defined in F3341/F3341M, UAS Terminology
Standard and F3060, Aircraft Terminology Standard. Terminology that is unique to this specification is defined in this section.
3.2 Definitions and Acronyms—The standard terminology for sUAS as defined in higher level standards applies in general to this
standard except as noted below.
3.3 Definitions of Terms Specific to This Standard:
3.3.1 C-rating, n—maximum steady-state current (amps) at which the battery cell or pack may be discharged without having pack
temperature exceed the CTT of its constituent cell(s) or result in a reduction in cell life. C-rating is expressed as a multiple of the
capacity. For example, a battery with a nominal capacity of 4 Ah may have a C-rating of 5C, meaning that 20 A would be
considered its maximum safe current.
3.3.2 characteristic thermal threshold, CTT, n—the temperature beyond which a rechargeable battery cell of particular chemistry
and structure will exhibit permanent deterioration of its critical performance parameters as evident upon subsequent charge/
discharge cycles. Cell capacity and internal resistance are critical performance parameters. CTT is rated at both upper and lower
thresholds.
