In the case of the values calculated by the μ 7.4 is greater than that indicated in the table, add the length of Current electrode and continue to find new ways for μ in 7.2 to 7.4.
In the case of the μ calculated under clause 7.4 is greater than that indicated in the table. Current electrode to increase the range of action already under way for the new μ in the 7.2 to 7.4.
In the case of the thermal, calculated by the 7.4 is greater than specified in the table, add stage of Current electrode then the percentage. Thermal, new method in the article 7.2 to 7.4.
