1. Byron Skillings, Ladish Proposed Rates: An Aerospace Perspective
ASTM E28.04 Workshop
Byron Skillings, Ladish
Proposed Rates:
An Aerospace Perspective

2. Ladish - Common Aerospace Test Rates
0.005 in/in/min to yield
0.05 in/min to fracture (ASTM E21 & Customer Req)
1 minute to fracture
0.002 in/in/min to yield
0.1 in/in/min to fracture

3. Ladish - E8 Proposed Test Rates
0.015 in/min to Yield
Proposed yield rate 5 to 7.5 X faster
0.45 in/min to fracture
Proposed to fracture rate X faster than present aerospace rates
