Scoping and writing the standard began in 2018. The goal is to have a completed standard published by the end of 2019 or early 2020. If the time frame to create this standard seems fast, that is one of the benefits of the UL standards development process. The UL standard development process uses a small drafting committee to create the first draft version of the standard. That drafting committee includes UL standards experts and a small number of subject matter experts. Once that first draft standard is completed, a group of diverse industry stakeholders and a broader group of subject matter experts will be recruited to review and provide feedback on the draft standard. This group, the Standards Technical Panel (STP), is a consensus voting committee and is being formed in Spring 2019. The STP will begin the first review upon the completion of the first draft standard. Once the approved standard is published, it will be under continuous maintenance, meaning that we expect periodic updates to keep up with technological advances as often as every six months.
