International pipe marking standard ISO20560-1 officially published

On September 24th a new international standard for pipe marking, the ISO20560-1, was officially published. This standard will meet the need for a uniform identification of safety information of piping systems.

Many years of preparations, concepts, research and, above all, international consensus underlie this new standard for pipe marking. Almost all countries have a (technical) standard for the marking of piping systems, but all with differences. In today’s international workforce, a uniform communication tool such as this standard for pipe marking contributes to the comprehensibility and especially the recognition of risks.

The starting point of this standard is a safety information philosophy in which technical information can be integrated. By designing the standard based on these principles, logical connections are made with existing standards for safety signs and worldwide standards for indicating hazards.

The safety color yellow (ISO3864) in combination with the hazard pictograms from GHS, and hazard symbols according to ISO7010, plays a central role in the composition of the pipe markings.

In addition to this example, many other innovations have been incorporated into this new international standard for pipe marking.

Blomsma Signs & Safety has been actively involved in the development of this standard. Together with internationally operating companies based in the Netherlands, we have provided on behalf of NEN an expert committee member and the chairmanship of this ISO working group that developed the standard.

We are convinced that this uniform standard removes ambiguities – such as the GHS and ISO7010 symbols conflict – and contributes to a clear information system to prevent incidents, among other things.

The standard is available via ISO, to be found under this link.
