Announcing New Standard ICC/BSR/PCI 155-202x: Specification for Test Method of Precast Concrete Insulated Wall Panel Wythe Connectors
This standard will establish test method protocol for the determination of wythe connector properties.
The Precast/Prestressed Concrete Institute (PCI), in collaboration with the International Code Council (ICC), is developing a new standard, ICC/BSR/PCI 155-202x: Specification for Test Method of Precast Concrete Insulated Wall Panel Wythe Connectors, to establish test method protocol for the determination of wythe connector properties.
Currently, designers rely on design properties, or entire insulated wall panel system design from wythe connector suppliers that may not be verified through a consistent test method across different connector types.
This standard provides test method protocol requirements for fabricating specimens and testing wythe connectors, typically used in precast concrete insulated wall panels, to develop wythe connector properties. This will aid designers in creating backbone curves to be used in insulated wall panel design.
A notification of intent has been submitted to the American National Standards Institute (ANSI). This notification was published in ANSI Standards Action Notice on Nov. 28, 2025, with inquiry and comment end date of Dec. 28, 2025.
More information about the proposed standard may be found at ANSI Standards Action, here.
