I am looking at a scenario of temperature compensation in a text book (Practical Guide to Inspection, Testing and Certification of Electrical Installations, 5th Ed. by Christopher Kitcher). In the example (Scenario 2, pp 128-129) the measured value of R1 + R2 is adjusted for temperature effects to get the R1 + R2 value at 70 degC. This (70 degC) value is now added to a measured Ze to obtain Zs which "can be compared directly to the maximum Zs values provided in chapter 41 of BS7671" according to this book.
This appears to not apply any temperature compensation to the Ze part of Zs whereas BS7671, App. 3, Page 363 adjusts the whole of Zs for temperature effects.
Am I missing something or making a mistake?
