Dear Queriest,
Your query is not clear to me but to tell you specific on the basis of my understanding your query, the FA as such does not categorized any Industry.
Your login title indicates that you are a safety guy and probably you would like to know the different provisions under FA, industry wise in respect to safety.
If it so, please refer the sections 85 to 91 of FA under the chapter IX which deals with Special Provisions. Also refer the applicable rules under the said chapter IX. On reading this chapter, one can come to conclusion that the FA categories industry / factory in to:
i. aid of power industry & non aid of power industry;
ii. public institutions maintained for the purposes of education; training research or reformation etc.;
iii. industry / factory scheduled as per dangerous operations, hazards, certain diseases etc.
I do not know whether you wanted to know this or some thing different.
