Type Testing In order to prove the design, material, heat treatment and method of manufacture, each size of component and chain has been type tested in the finished condition in order to demonstrate that the component and chain possesses the required mechanical properties. The following testing procedures are particularly relevant: - Test for Deformation: The Manufacturing Proof Force (MPF) for the relevant size of the component is applied and removed. The dimensions after proof loading shall not alter from the original dimensions within the tolerances prescribed in our specifications and in the international standards. - Static Tensile Test: The Breaking Force (BF) for each component and size is verified. The verified value shall be at least equal to the Minimum Breaking Force (MBF) value. The MBF value is equal to the Working Load Limit (WLL) multiplied by the safety factor. - Fatigue Test: By fatigue testing in pulsator testing machines the toughest condition of service is simulated.

Manufacturing Testing During manufacture continuous process tests are carried out according to the requirements in our specifications and in the latest international standards. The following testing procedures are particularly relevant: - Proof Force: Each individual component and chain link is tested to the Manufacturing Proof Force (MPF) level before delivery. The MPF level is 2.5 times the WLL, equal to 62,5% of the Minimum Breaking Force. - Non Destructive test/ Visual Inspection: 3% of every production batch of forged components are subject to magnetic particle or dye penetrating examination. Visual inspection is carried out on each chain link and each forged component to detect defects. - Static Tensile and Ulitmate Elongation test: During manufacture, samples are tested and the Minimum Breaking Force (MBF) value and the total ultimate elongation are verified. - Bending Deflection: During manufacturing, of chain and master links, samples are taken and the minimum bend deflection is verfied.
