I want to use this website in my report but I do not see the produced year of the following pdf https://www.astm.org/BOOKSTORE/DS68/pg41.pdf
How can I do the reference of that pdf ?
Is this correct : ASTM international, "Ultrasonic Testing," ASTM international,. [Online]. Available: https://www.astm.org/BOOKSTORE/DS68/pg41.pdf. [Accessed September 2016].
Thanks
