USGA Summary Points: | In 1999, a research project was initiated by the USGA Green Section to investigate sources of interlab variability associated with ASTM Method F1 815-97, with specific attention to the determination of saturated hydraulic conductivity. Results of the USGA-PT'program have indicated inter-lab variability of 25% or more for 42 rootzone mixes evaluated since January 1997. Results of the laboratory visits indicate inconsistency between laboratories in Steps #1 (loading the rootzone in the test cylinder, see Appendix A), Step #2 (initial saturation of the rootzone mix), Step #3 (initial 30-cm moisture tension) and #6 (measurement of water flow) of the method. Research has evaluated two approaches to resolving the inter-lab variability of ASTM F1 815-97 and developing a more robust method. The first addresses subjective steps in the method and improving the method description. The second proposes to revise the existing protocol, remove problematic steps, and utilize a predictive moisture model. |
