BS EN 4180 standard is part of the series of EN metallic material standards for aerospace applications.
BS EN 4180 specifies the dimensions and tolerances of circular tubes, for fluids in titanium and titanium alloys wide tolerances diameter 4 mm ≤ D ≤ 40 mm for aerospace applications.
BS EN 4180 on dimensions and tolerances of circular tubes is useful for:
Pertaining to circular tubes, BS EN 4180 includes the form; recommended dimensions in terms of diameter, thickness, mass, length; tolerances like dimensional tolerances in terms of diameter, thickness, and length; geometric tolerances like straightness in terms of method of measurement and symbols, tolerances; roundness in terms of method of measurement and symbols, tolerances; and eccentricity in terms of method of measurement and symbols, tolerances.
The testing method in BS EN 4180 can serve as a guide to testing agencies, organizations and manufacturers of circular tubes.
