Short answer
End-to-end electrical continuity is evaluated between defined connection points on the completed hose assembly. Information given about the hose body or the metal reinforcement does not replace the measurement result for the finished assembly.
Technical explanation
Electrical behavior can depend on the internal construction, reinforcement, end fittings and contact conditions. ISO 8031 covers the relevant measurement methods in this area; the acceptance limit must be taken separately from the product and application source. A change of fitting or seal can affect the measurement path. The continuity result is an assessment separate from chemical compatibility and mechanical integrity. A single successful measurement is not a permanent guarantee for the entire service life.

| Instrument | Suitable method and measuring range |
| Criterion | Product- and application-dependent source |
How to evaluate it in practice
Write the assembly number and the two measurement points on the test record. Prevent the old report from being used automatically if the ends are removed or replaced. Record the source of the acceptance criterion and the instrument range. The suitability of the instrument for low-resistance or high-resistance measurements must be checked separately. The test is carried out under safe and defined conditions; do not use a live hazardous line as an improvised measurement setup. Store the result together with the method information, not just with a 'conductive' label. Do not interpret a continuity result as compliance unless the measurement path, the instrument and the acceptance limit valid for the product have been defined.

Frequently asked questions
Does a wire-reinforced hose make a continuity report unnecessary?
No. The actual measurement path, including the ends, and the completed assembly must be verified.
