Intent | Intent 1: To limit the probability that the performance of air filters,
with respect to flammability and smoke production, will fall significantly
below expectations, which could lead to their igniting and producing unacceptable
amounts of smoke under in-service temperatures, which could lead to harm to
persons. |
