JIS Instrumentation Symbols – Japanese P&ID Conventions

Japan has its own JIS standard for instrumentation symbols on process diagrams.

Specific symbol mappings are added after verification. Until then the shared InduDraft symbol is drawn, and the engineering data stays the same.

Engineering drawings are not drawn exactly the same way everywhere. Japan has its own JIS standards, including one for instrumentation symbols.

What is JIS Z 8204?

JIS Z 8204 defines instrumentation symbols used to represent measurement and control functions on process-related diagrams in Japan.

The current 1983 edition remains valid and was reconfirmed in 2024.

Why does this matter?

If you work with Japanese project documentation, you may meet conventions that differ from the ISA or ISO-based drawings you know. The equipment does the same job. Only the graphical language used to describe it changes.

How InduDraft handles JIS today

The JIS profile is available in the editor. JIS-specific symbol verification is in progress, so the profile draws InduDraft's shared engineering symbols where a verified JIS representation is not yet available. We won't draw a JIS symbol we haven't checked. See InduDraft's JIS P&ID editor.

The JIS profile uses shared InduDraft engineering symbols until JIS-specific mappings are verified.
