Leak testing has become a major aspect of many processes in a wide range of industries, from castings to crisp packets. But it seems it is often shrouded in "secret formulas" and specialist knowledge, known only to the leak test manufacturers. Have you ever asked: - What is my leak specification? - Can I set up my air pressure tester myself? - How do I check/calibrate my leak test machine? - Would a helium test be better? - Why is my leak test failing good parts? - What are the problems I need to be aware of? - Who can I ask for honest help and advice? Many of you will already know the wealth of knowledge the author brings to this subject, and how he makes even the complicated easy to understand. Now retired from industry, Barry wanted to share his knowledge with anyone who wants to be an expert in this field or simply has an interest and wants to know more. With this easy-to-follow guide, you can call on all of Barry's vast experience in all aspects of leak testing, including air under water, pressure decay, flow measurement, helium leak testing, gas sniffers and many more. The book guides you through all you need to know, from the basic mathematics, through developing your leak specifications, selection and setting up your leak test, right through to fault diagnosis and effective maintenance. Leak Testing Made Easy does exactly what it says, taking the mystery of the subject, and making it simple and practical to understand, with many pictorial examples, along with lots of practical analogies to common-day things that you already know about. Packed with look-up tables and charts, this book is a must for any specifiers and users of leaks and leak testing equipment, or simply for those who would like to know more.
