HIC Testing and the "HIC D" Grade, Second-Stage Vacuum Condenser
•Crack Length Ratio (CLR) ≤ 5%
•Crack Thickness Ratio (CTR) ≤ 1.5%
•Crack Sensitivity Ratio (CSR) ≤ 0.5%
In some extremely severe service conditions, the specification may require all three indices to be 0%, meaning no detectable cracking is permitted.
