BS ISO 1161:2016 pdf download – Series 1 freight containers — Corner and intermediate fittings — Specifications 8 Required tests 8.1 General The test set forth in 8.3.1 to 8.3.12 are to be conducted on each fitting except for those produced using a batch process. For a batch process, a minimum of 2 % of the fittings in each batch shall be tested. Test pieces must be randomly selected by the Certification Society from the batch under heat treatment at the time. At the end of each test, the fitting shall show no permanent deformation. A full dimensional check to ensure compliance with this International Standard, with respect to aperture dimension, wall thickness and overall dimensions, shall be done on each fitting. 8.2 Casting defect checks 8.2.1 A visual check for defects shall be done on the exterior and interior surfaces of each fitting. All defective fittings shall be destroyed. 8.2.2 A suitable non-destructive test (e.g. X-ray or ultrasound) shall be performed on one fitting from each casting batch. If defects are found, all fittings in the batch shall be tested. All defective fittings shall be destroyed. 8.3 Tests 8.3.1 The mechanical properties shall be checked and conformance with the minimum material properties set forth in Clause 4 confirmed for each heat and furnace lot of metal used to produce cast fittings. For fabricated fittings, each sheet of material used shall be tested and conformance confirmed. 8.3.2 Top fitting stacking test — The fitting shall be supported vertically on a typical corner post and horizontally by structures similar to typical cross sections for header and top side rail. The top face of the fitting shall be subjected to the full ISO load (942 kN) + 10 %. The load shall be applied perpendicular to the fitting equally distributed over the fitting’s top face. The load shall be applied for a minimum of 2 min. 8.3.3 Top intermediate fitting stacking test — The fitting shall be supported vertically on a typical intermediate post and horizontally by structures similar to typical cross sections for intermediate headers and top side rails. The top face of the fitting shall be subjected to the full ISO load (423 kN) plus 10 %. The load shall be applied perpendicular to the fitting equally distributed over the fitting’s top face. The load shall be applied for a minimum of 2 min. 8.3.4 Bottom fitting stacking test —...
