Although the International Organization for Standardization and American National Standards Institute are among the organizations that create codes, standards and certification programs to ensure the quality and safety of manufactured products, their standards do not reflect the current mechanical safety and reliability needs of the modern wind turbine.
Although the International Organization for Standardization and American National Standards Institute are among the organizations that create codes, standards and certification programs to ensure the quality and safety of manufactured products, their standards do not reflect the current mechanical safety and reliability needs of the modern wind turbine.
In particular, standards may not be adequate for fasteners applicable to more demanding applications where cyclical loads, thermal cycling and other severe conditions are present. These conditions are often present in mechanisms such as wind turbine blade root bolts, gearboxes and drive mechanisms.(…)
