Starting after 1970, what was modern carpet manufactured in the US required to do?

Starting after 1970, modern carpet manufactured in the United States was required to comply with specific fire resistance standards. This regulation arose from increased awareness and concern for fire safety, particularly in residential and commercial settings. The standards addressed the flammability of materials and aimed to reduce the likelihood of fire spread, which was crucial in safeguarding lives and property.

The development of these fire resistance standards involved testing materials for their ability to prevent ignition and to limit flame spread once ignited. Compliance with these standards would require manufacturers to incorporate materials and treatments into their carpet products that significantly enhance their fire performance, thus protecting consumers from potential fire hazards.

The focus on fire resistance takes precedence over aesthetic qualities or the specific use of synthetic versus natural fibers. While those factors may contribute to the overall quality and appeal of carpet products, the safety aspect became paramount in regulations established after 1970, reflecting evolving safety standards in response to changing fire safety concerns.
