g) Added requirements for on-site test conditions (see 4.5.6.1);
h) Changed the test content and requirements of the field test method (see 4.5.6.1~4.5.6.6, 4.3.2.1 of the.2011 edition);
i) Deleted the test records and related formats (see Chapter 5 and Appendix A of the.2011 edition);
j) Added the calculation formula for the power consumption of the process host (see 5.2);
k) Added basic requirements for electrical energy efficiency test reports (see Chapter 6).
