42、 Instead of sampling in accordance with PracticeE255, the manufacturer shall have the option of taking samplesat the time the castings are poured or by taking samples fromthe semi-finished product.14.1.2.1 When composition of the material has been deter-mined during the course of manufacture, sampli
43、ng of thefinished product by the manufacturer is not required.14.1.3 The number of samples to be taken for determinationof chemical composition shall be as follows:14.1.3.1 When sampled at the time the castings are poured,at least one sample shall be taken for each group of castingspoured from the s
44、ame source of molten metal.14.1.3.2 When sampled from the semi-finished product, atleast one sample shall be taken to represent each 10 000 lb, orfraction thereof, except that not more than one sample shall berequired per piece.14.1.3.3 Only one sample need be taken from the semi-finished product of

48、1. METRIC EQUIVALENTSX1.1 The SI unit for strength properties now shown is inaccordance with the International System of Units (SI). Thederived SI unit for force is the newton (N), which is defined asthat force which when applied to a body having a mass of onekilogram gives it an acceleration of one
49、 metre per secondsquared (N = kgm/s2). The derived SI unit for pressure orstress is the newton per square metre (N/m2), which has beennamed the pascal (Pa) by the General Conference on Weightsand Measures. Since 1 ksi = 6 894 757 Pa the metric equiva-lents are expressed as megapascal (MPa), which is the same asMN/m2and N/mm2.SUMMARY OF CHANGESCommittee B05 has identified the location of selected changes to this standard since the last issue (B592 01(2006) that may impact the use of this standard.
