Comparison of ASTM D1693 and D 5397 NCTL ESCR

Comparison of ASTM D1693 and D 5397 NCTL ESCR

We have a specification for HDPE which calls for the material to meet 10,000 hours when tested in accordance with ASTM D1693 F50

The material has been tested to ASTM 5397 NCTL at 50 degree c and failed after 200 to 600 hours.

Is there any way that I can correlate the different tests?

In a word no. Sorry.
