Notice: The ANSI Board of Standards Review has approved ANSI/ISANTA SNT-101, 2024, Safety Requirements for Portable Compressed-Air-Actuated Fastener Driving Tools. The approved standard replaces the 2015 version of SNT-101 as of its September 19, 2025 effective date.  SNT-101, 2015 remains effective until that date. 

The 2024 standard makes significant advancements toward the goal of promoting the safe use of hand-held fastener driving tools. The 2024 edition places additional responsibilities on manufacturers, employers and users of pneumatic fastener driving tools. Manufacturers, employers and users should familiarize themselves with the additions and modifications. ISANTA thanks its members and all of those who served to review and revise the proposed standard. 

This standard (when adopted by a country) specifies the safety requirements for hand-held non-electric fastener power tools. Copies are available for purchase on the ISO website. Click the following link to be redirected. ISO-11148-13:2017
