ICC-ES AC542
Full Name
ICC-ES AC542 – Acceptance Criteria for Precast Hemp-lime Infill Panels For Use In Light-frame Construction
Scope
ICC-ES AC542 outlines the acceptance criteria for evaluating precast hemp-lime infill panels for use in light-frame construction. AC542 is intended for manufacturers seeking approval for their products under the ICC-ES evaluation report program.
The scope of AC542 covers:
- Materials: defines the acceptable types of hemp hurd, binders (such as hydraulic lime and natural cements), and water additives that can be used in the production of precast hemp-lime infill panels.
- Performance requirements: specifies the structural, thermal, and durability properties that the panels must meet, including requirements for compressive strength, thermal resistance, and moisture resistance.
- Test methods: outlines the specific tests and procedures to be followed to evaluate the performance and compliance of the panels with the specified criteria. This may include compressive strength testing, thermal testing, and moisture resistance testing.
- Quality control: details the quality control measures that manufacturers must have in place to ensure consistent product quality and compliance with the acceptance criteria. This may include requirements for material testing, production monitoring, and record-keeping.
- Installation: provides guidance on proper installation methods and detailing for the precast hemp-lime infill panels to ensure optimal performance and integration with light-frame construction.
