Pipe marking according to ISO 20560-1 standard
Installing pipe line marking with clear and universally recognisable formats is essential to global and local safety and maintenance.

The key points
An Industry Standard pipe marker consists of 4 basic elements:
1. Basic identification colour
2. Name of the substance/content
3. Flow direction indicators (arrows)
4. Warning symbols, GHS symbols (or both)

Hazardous substances | Alkalis |
Gas (liquid or gaseous) | Fire fighting medium |
Liquids & solids (powder/granulate) | Water |
Acids | Air |
A significant benefit of the ISO 20560-1 standard is the establishment of basic identification colours, the colour coding will be used worldwide. This is essential for both industry and emergency services

Pipes up to 150mm

Pipes from 150mm ~ 500mm

Pipes from 500mm
Other guidelines and rules
There are a few additional guidelines that determine the layout, positioning and visibility of a pipe marker.
• The minimum letter height is 7mm and symbols must be at least 20mm high
• The minimum height of the flow indicator (arrow) is 10mm
• Pipes that are visible on two sides require (pipe) markings on both sides
• Pipe markings should be placed at key locations such as junctions, valve breaks and branch points, on both sides of walls and other zone boundaries and at the beginning and end of pipe racks etc.
