Materials and storage: All material lifespan (ie not corroded) in storage conditions (temperature -30 °C to +35 °C, relative humidity 60%) has to be at least 10 years.
Packing and marking
- Basic package (for one roll): Must ensure smooth cargo handling (loading, lifting) and prevent hand injuries by wire.
- Transport package marking: Transport package has to contain min. of 10 and max. 50 basic package (one roll). Basic packages has to be packed in to transport package in a way that ensures smooth and safe handling.
