Test
Surface quality
All tubes shall be free of excessive mill scale, suitable for inspection. A slight amount of oxidation will not be considered as scale. Any special finish requirements shall be subject to agreement between the manufacturer and the clients.
Tubes shall be delivered with square cut ends. The ends are free of excessive burrs.
The tubes are bundled in the waterproof plastic sheet and packed in the wooden cases
The case is most suitable for hanging by forklift.
EN10204-3.1 MTC shall be issued
EN10204-3.2 MTC is as option
