Standards and compliance
The manufacturer documents the following:
- EN ISO 1307:2008.
The manufacturer states no electrical resistance for the hose, so it must not be used for combustible dust.

Help with material selection
Although this hose isn't ATEX-relevant, these two articles provide useful background on electrical resistance and industrial safety — important if you later combine the hose with electrical equipment or work in mixed environments:
The invisible weakest link
Why a conductive or antistatic hose isn't sufficient on its own — and what grounding means for the complete system.
Know your ohm
The difference between antistatic and conductive, which resistance limits apply where, and how to measure them correctly.
Industries that use it
The hose is used in:
Industry and agriculture for water, slurry and oils.
Custom lengths and assemblies
The hose can be cut to length and assembled with couplings. We advise on the assembly so the hose fits your installation.
Frequently asked questions
Is the hose antistatic?
The name contains AS and the manufacturer states an embedded copper wire, but gives no electrical resistance. The hose must therefore not be used for combustible dust. Contact us if you need a hose with documented resistance.
