Nigel J Ford the author has written this book in a most pleasant manner to read and for retention of the reader. Not complicated and therefore needing to look up other books on the subject matter. The content is aimed at a sensible level which the author I feel has achieved, and covers all that is necessary to attain a firm grasp of the title..Portable Appliance Testing. I found the book a relaxing and informative read and most educational no matter what level of understanding one has of PAT testing. Recommended as a reference in one's library if PAT testing is your vocation.
