Other than ISA for instrument identification (ISA 5.1/5.2 Alternatives?)

[AfigueredoU]

Hello Collegues, I have a question, is there any other instrumentation code different than ISA 5.1/5.2, I asked because I'd received some P&ID with a "strange" codification that does not fulfill the requirements of the clasic PIT-XXX, TIT-XXX used almost everywere.

Thanks;

AF.
