Hi All, I am aware that ISA S5.1 has been the de-facto international standard for Instrument Symbols and Identification. However in Australia we had AS
1101.6 (modeled after ISA S5.1) as the national standard. This standard has now become OBSOLETE. If any Australian members of this group (Cameron??) are aware of a replacement standard for AS 1101.6, please let me know.As far as I know, there are no equivalent IEC standards to ISA S5.1. ISO has adopted a new standard ISO 14617.6 (ISO 14617 series) in 2002 and British Standards has adopted this as BS 14617.6 in 2004.
Has any one used ISO 14617.6 to define Instrument Symbols? Is it a one-to-one replacement for ISA S5.1? Back in 2004, ISA was considering updating S5.1 to cater for Fieldbus Instruments (Foundation Fieldbus, IEC
61508 / IEC 61511 compliant instruments, Profibus, ASi etc). Is anyone aware of where this standard update effort is headed? Any help or pointers in this regard will be much appreciated. Thanks and regards, Raj Sreenevasan
