NOTE 1 The designation is irrespective of the type of cast sample
NOTE 2 For high damping capacity and thermal conductivity, EN-GJL-100 (5.1100) is the most suitable material.
NOTE 3 The figures given in bold indicate the minimum tensile strength to which the material designation of the grade is related. The values relate to an as-cast sample diameter corresponding to the applicant relevant wall thickness range according to table 3.
NOTE 4 For relevant wall thickness more than 200mm, the manufacturer and the purchaser shall agress on the type and size of cast sample and the minimum values to be obtained.
a If tensile strength is specified as a characterizing property, the type of the sample (see 8.2) should aslo be stated in the order. If not stated in the order, the type of sample is left to the discretion of the manufacturer.
b This value is included as the lower limit of the relevant wall-thickness range.
