The strength calculation method specified in Lloyd's Register:2013 has now been implemented. This specific standard for ships is now widely required as a proof. GOST 21354-87 for manufacturing tolerances, and GOST 1643-81 for tooth thickness allowances of cylindrical gears are now also available. The existing calculation methods have been extended by the ISO 13691 standard ("high-speed special-purpose gear units"). For the VDI 2736, seven new plastics have been added for high temperature applications with SN-curve data.
