5、y in the slurry con-tainer should be increased in accordance with the appropriate well-simulation test schedule(see 9.5).Schedules may be calculated or taken from the tables.Temperature of the cement slurry shall be determined by use of an ASTM classification“special”Type J thermocouple(see Appendix
6、 B)located in the center of the sample container.The tip of the thermocouple shall be vertically positioned,within the paddle shaft,in the slurry cup in such a way that it is between 1.75 in.(4.45 cm)and 3.50 in.(8.89 cm)above the inside of the base of the sam-ple container.As there are many models
7、of consistometers having different dimensions,care must be taken to ensure that the thermocouple used is compatible with the consistometer and the position of the tip of the thermocouple is in the correct location specified above.Page 22,Equation(8b)The constant should be 9.776.Page 87,Section 10.6.
