NOTICE:
drafting of the following internal standards is underway:
- ZN-G-3870 Guidelines for pipeline design in mining areas,
- ZN-G-3871 Pipelines – Pipeline curves laid down in the ground – requirements and tests
- ZN-G-3872 Pipelines – Ballasting pipelines laid down in water or watered ground – calculations.
The internal standard ZN-G-3150:1996 Gas pipelines – polyethylene pipes – requirements and tests is expected to go out of force in the near future.
