--- Changed normative references (see Chapter 2, Chapter 2 of the.2010 edition);
--- Added terms, definitions and symbols (see Chapter 3);
--- Delete the relevant provisions of the test content (see 3.1 of the.2010 edition);
--- Increased test assurance requirements (see 4.2);
--- Changed the pump test acceptance level and the corresponding tolerance coefficient value (see Table 2, Table 7 of the.2010 edition);
--- Added the definition of K in the calculation formula of the straight pipe length (L) of the inlet section (see 4.3.2);
--- Increased the accuracy requirements of instruments (see 4.3.3.2);
--- Changed the allowable fluctuation range of the measured value (see Table 3, Table 2 of the.2010 edition);
--- Added "Level 3" related requirements (see 4.5.1.2, 4.5.1.3, 4.7.8, 4.7.4.3.4);
--- Delete the provisions for the system uncertainty of each measurement parameter (see Table 1 of the.2010 edition);
--- Delete the situation that the maximum allowable fluctuation range is large when the transmission signal of the measurement system is automatically recorded or accumulated by the measurement device (see
3.3.1.2.2 of the.2010 version);
--- Changed the relevant provisions of "number of observation groups" (see Table 4, 3.3.1.3 of the.2010 edition);
--- Delete the relevant requirements for the determination of measurement uncertainty (see 3.5.7 of the.2010 edition);
--- Increased the operating thermal stability requirements of the motor (see 4.5.1.4);
--- Increased the length requirements for the cables leading out of the test pump (see 4.5.3);
--- Changed the no-load test of the motor (see 4.6.3, 3.4.3.1 of the.2010 edition);
--- Increased the requirements for reducing the current load method (see 4.6.4.2);
--- Changed the range requirements of winding temperature rise at rated power [see 4.6.5.2, 3.4.4.2b) of the.2010 edition];
--- Changed the test requirements (see 4.7.1, 3.5.1 of the.2010 edition);
--- Increased the guarantee conditions during the test (see 4.7.2);
--- Added test curve requirements (see 4.7.7.2);
--- Increased the tolerance of the guaranteed value of the motor parameters (see Table 6);
--- Changed the test of self-priming performance (see 4.10, 3.8 of the.2010 edition);
--- Increased safety requirements (see 4.11).
