Siding
Siding is the difference between the maximum and minimum wall thickness in a measured plane.
| Wall thickness | Maximum values siding |
| < 0. 80 mm | 7% of the wall thickness |
| ³ 0. 80 mm | 8% of the wall thickness |
Straightness
Straightness according to ISO 1101 is based on the following maximum values:
| OD | Maximum value t |
| 4-6mm | 4.0 mm/ 1500 mm |
| > 6mm | 1.0 mm/ 1000 mm |
Stress
| Longitudinal stress | max. 4.0 MPa |
| Edge stress | max. 4.5 MPa |
Stones and knots
Stones are opaque inclusions, knots are transparent inclusions. Stones and knots with a core diameter of ³ 0.5mm are regarded as faults. (Detailed information on permissible faults, definition of faults, testing methods and testing units is available on request.)
Airlines
Airlines are an elongated, gaseous inclusion along the length of the tubing, which is generally not visible to the naked eye. The aggregate airline length is defined by adding together the length of all airlines > 15 mm (or in the case of two or more overlapping airlines, the distance between the extremities of the airlines concerned). A cumulative airline length of > 1.25 m per 10m of tubing is regarded as a fault. (Detailed information on permissible faults, definition of faults, testing methods and testing units is available on request.)
Scratches
A scratch represents a slight surface defect which neither penetrates the depth of the wall, nor permeates it in any way and therefore has an insignificant effect on the mechanical stability. Tubing of 5-30 mm outside diameter can be coated for protection against scratches.
Tubing End Finishes
End finish: plain cut and fused
Standard: medium-fused with a fusing thickness of 0.15 mm
Other tubing end versions:
Fusing Thickness - Slightly
