h) The high and low temperature requirements have been changed (see 5.4.2,.2008 version 5.4.2);
i) Electromagnetic compatibility requirements have been added (see 5.4.10);
j) Increased driving force requirements (see 5.7);
k) Added differentiation of measurement levels for testing equipment (see 6.2.1);
l) A zero-point flow fluctuation test method has been added (see 6.5.6.5);
m) A transient response test method has been added (see 6.6.3);
n) An electromagnetic compatibility test method has been added (see 6.13).
