Standards (consensus and/or regulatory) applicable to HILTI Direct Fastening tools

I'm looking for the applicable standards for HILTI direct fastening tools. I'm not looking for the OSHA standards. I know the Powder actuated tool falls under ANSI/ASSP A10.3-2020, "Safety Requirements for Powder-Actuated Fastening Systems". (I know the OSHA Standards 29 CFR 1926.302(e) still references ANSI A10.3–1970, "Safety Requirements for Explosive-Actuated Fastening Tools"), I'm looking for information on the applicable standards for:
HILTI Gas-Actuated Fastening Tool (GX 3) 

HILTI Battery-Actuated Fastening Tool (BX 3) 
If not an ANSI standard, whatever certification or consensus standard would be helpful.
