Question: 1 / 400

Which class of material would a wallcovering material belong to if it has a flame spread rating of 125?

Class A

Class B

Class C

A wallcovering material with a flame spread rating of 125 would actually fall under Class B. The classification of wallcovering materials is based on their flame spread index as determined by standardized testing.

Class A materials are those with a flame spread rating of 0-25, indicating a very low rate of flame spread. Class B materials have a rating between 26-75, which allows for some flame spread but is still considered relatively safe. Class C materials, on the other hand, are assigned ratings from 76-200. Given that a rating of 125 falls within this range, it qualifies as Class B rather than Class C. The classification matters significantly for safety and compliance in building codes and regulations.

In summary, a wallcovering material with a flame spread rating of 125 is classified as Class B due to its performance characteristics in terms of flame spread.
