Ceiling systems which are more durable and damage-resistant, in addition to those that have various levels of cleanability, minimize the need for frequent replacement and disposal.

 Falling Ball Impact Test  (Modified ASTM D 1037 Procedure)

Ceilings in areas like school corridors or gymnasiums need to withstand abuse, including surface impact.  The Falling Ball Impact Test evaluates a ceiling's impact resistance.

 Hess Rake Test

In any areas where lay-in ceiling panels frequently need to be removed for plenum access, surface scratch resistance is highly desirable.  The Hess Rake Test evaluates surface scratch resistance.

Minimize Damage

Downward access for Vector panels minimizes panel damage from hanger wires and other obstructions. See products with Vector™ edge detail, pages 35, 36, 55, 56, 131-134, 159-160.



 Simulated Supply Air Diffuser Soiling Test

Dirt accumulation not only detracts from a ceiling's appearance, but can cost money by requiring painting or replacement of the ceiling.  In addition to reducing acoustical efficiency, soiling can cause a substantial reduction in light reflectance.  Most Armstrong Hi-LR ceilings provide excellent soil resistance for lasting value and performance.
The Simulated Supply Air Diffuser Soiling Test evaluates this soil-resistant property.

 Washability Test (ASTM D 4828)
Ceilings installed in laboratories, clean rooms, food preparation areas, and other sanitary applications are required to meet washability standards.  The Washability Test evaluates a ceiling's ability to withstand washing.

  Scrubbability Test (ASTM D 2486)
Ceilings installed in laboratories, clean rooms and food preparation areas are required to meet scrubbability standards - and, sometimes, other specific criteria.  The Scrubbability test evaluates a ceiling's ability to withstand scrubbing.
