Material Allowables and Testing

• All tests are performed according to ASTM Standards.
• ASME etc. codes are used whenever seems necessary.
• To determine the material allowables the following tests are carried out
• Coupon tests (Tension, compression, shear, bending etc.)
• Elemental tests and joint tests
• Sub-component and component tests are almost impossible to carry out due to the size and generally unnecessary for material allowables.
• As the material allowables A-Basis or B-Basis values are used depending on the customer requirements
