bulkhead fire rating 1

[wilber]

I have been asked if a Underwriter's Laboratories Type MC cable will compromise a A-60,H-60 fire-rating of bulkheads when making a multi-cable transit (MCT's) when passing through them. This job is on offshore platform project near Kuala Lumpur, Malaysia.
I am familiar with "through penetration" for walls in the US, but not an A-60 and H-60.
Does anyone know where I can get information on maintaining to these ratings?
