Scope of Standards Developing Activity

UL Standards are developed using a procedure that provides for participation, review, and comment from groups representing a broad range of interests including industry, government, insurance groups, consumers, other interested parties, and the general public. This procedure takes into consideration the needs and opinions of a wide variety of interests concerned with the subject matter of the standard.
A majority of UL’s standards are recognized as American National Standards, or ANSI standards. ANSI/UL Standards are developed and reviewed through the UL Standards Technical Panel (STP). An STP is a balanced group of individuals representing a variety of interest categories, which is formed to review UL proposals and discuss UL Standards-related issues. The STP serves as the consensus body to review and vote on proposals prior to publication.
UL develops standards addressing the following types of equipment:

  • Electrical Components
  • Electronic Equipment
  • Wire and Cable
  • Appliances
  • Information Technology Equipment
  • Fire Protection Equipment
  • Fire Suppression Equipment
  • Signaling and Alarms
  • Equipment for use in Hazardous Locations
