NCIDQ Interior Design Professional Exam (IDPX) Practice Exam

Question: 1 / 400

What is the purpose of the CAL 133 test?

To evaluate flame resistance of individual materials

To test for sound absorption of upholstery

To assess fire behavior of entire pieces of furniture

The California Technical Bulletin 133, commonly referred to as CAL 133, is specifically designed to assess the fire behavior of entire pieces of furniture rather than just individual materials. This test simulates real-life scenarios to determine how upholstered furniture will react in the event of a fire. By evaluating factors such as ignition time, heat release rates, and smoke production, CAL 133 helps ensure that finished furniture pieces can resist fire to a certain degree, thereby enhancing safety for occupants in commercial and public spaces.

CAL 133 is mandatory for many applications, especially in settings like hotels, theaters, and other public venues where the risk of fire hazards is a significant concern. Therefore, its focus is on the performance of the complete assembly of the furniture item, making option C the correct choice as it reflects the intent and comprehensive scope of the CAL 133 test.
