cold form steel truss fire damage

I have been asked to determine if a cold form steel roof truss has sustained fire damage. Visually the truss appears to be fine with no evidence of high heat except for smoke and fire retardant spray by the fire department.

Can someone direct me to a guide on the assessment of cold form steel trusses for fire damage?

Thanks in advance.
