What Is ASTM D8662/D8662M-26?
ASTM D8662/D8662M-26 is the Standard Specification for Plastic Temporary Ceiling Construction Barriers for Installation Below Automatic Sprinklers. It applies to temporary barriers made of panels connected by seams and used during roof or ceiling construction and renovation.
The specification is intended for barriers that protect occupants, workers, and equipment from dust and light debris. It does not cover protection from heavy falling debris.
What Does the Specification Address?
Sprinkler Access
The barrier must be able to open during a fire so it does not interfere with sprinkler operation.
Strength
It must withstand specified pressure loads associated with its temporary use.
Durability
It must withstand pressure changes over time
Fire performance
It must meet the fire test requirements identified in the specification.
Installation
It must be installed according to the specification’s requirements and the product’s instructions.
Duration
It is intended for use for no more than six months unless the authority having jurisdiction approves a longer period.
Why Does ASTM D8662/D8662M-26 Matter for Your Project?
- It gives you a specification written for this exact application. A general plastic sheet may catch dust, but that alone does not establish that it is suitable beneath sprinklers.
- It considers everyday performance and fire conditions. The barrier needs to remain in place during construction while being able to open when fire occurs.
- It helps your team ask for the right documentation. Contractors, facility managers, and fire protection teams can request evidence that a proposed system meets the specification’s requirements.
- It helps prevent a late change to the project. Reviewing the barrier and its installation before work begins is easier than replacing a system after a fire protection concern is identified.
