What does CAL TB133 (NFPA 266) involve in its testing?

1. A theoretical model of furniture safety

2. An actual sample of furniture

3. General manufacturing quality of furniture

4. Assessment of aesthetic design in furniture

The correct answer is: An actual sample of furniture

CAL TB133 (NFPA 266) involves testing an actual sample of furniture to assess its flammability and response to fire hazards. This testing protocol requires the use of full-scale furniture pieces subjected to specific fire conditions to determine how they ignite, burn, and contribute to fire spread. The focus is on assessing the material's performance in real-life scenarios, which provides crucial data for fire safety regulations. The emphasis on testing actual samples underscores the necessity for practical evaluations in fire safety standards, as theoretical models or assessments of general manufacturing quality do not adequately represent how a piece of furniture will behave in a fire situation. Also, aesthetic design is not part of the evaluation criteria; rather, the goal is to ensure the safety and protection of building occupants by examining the flammability characteristics of the furniture itself under controlled test conditions.
