Under 16 CFR 1632, the flammability of mattresses and mattress pads is tested by exposing the material to a smoldering cigarette.
The maximum allowable char length is 2 inches (51 mm).
This standard ensures that the material does not ignite or propagate fire.
Larger char lengths indicate excessive flammability and would fail the standard.

I remember 2 inches being mentioned, but I thought that was for older standards. I hope I’m not mixing it up!

I’m leaning towards 5 inches, but I can't recall if that was for a different standard. It’s confusing with all the regulations we studied.

I feel like I saw a question similar to this in our practice exam, and it might have been 3 inches. I need to double-check my notes.

I'm a little confused by the technical details in this question. I'll make my best guess, but I might need to come back to it if I have time at the end of the exam.

This seems like a straightforward question, but I want to double-check the units to make sure I'm interpreting them correctly. I'll convert the measurements to the same unit to help me compare the options.

Okay, let me think this through step-by-step. The question is asking about the maximum char length, so I'll need to focus on that specific detail in the standard. I'll eliminate any answer choices that don't seem to match that criteria.
