Civil Engineering Association

Dear friends and colleagues,

for the needs of my work in the field of non-destructive testing of structures I'm searching for these standards:

1. ASTM C 876 - 09 Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete.
2. ASTM E797 / E797M - 10 Standard Practice for Measuring Thickness by Manual Ultrasonic Pulse-Echo Contact Method

Please, don't upload earlier editions, because I have them.
Thanks in advance.
