1)The values specified are approximate values for the 0.2% proof stress and it is not required to verify them.This should be taken into account in design by using a higher safety certification(e.g. as in DIN 2413-1972 editon,subclaus 4.1.2,the value shall be increased by 20% for category Ⅱ).
2)For the range between 20℃ and 50℃ and 200℃，linear interpolation should be made.It is not oermitted to round the values.
