  1. The listed values are effective 08 2006 and are subject to change without notice.
  2. Values are MARV (Minimum Average Roll Value calculated as the typical minus two standard deviations, statiscally yielding a 97.7% degree of confidence that any sample taken during QA testing will exceed the reported value) unless indicated as Typical.
  3. Calculated as percent increase in average plant biomass with tall fescue grass seed in sand 14 days after seeding versus traditional monofilament TRMs and HPTRMs.
  4. All components must meet UV resistance values.
  5. Maximum permissible shear stress has been obtained through fully vegetated (70% to 100% density) testing programs featuring specific soil types, vegetation classes, flow conditions and failure criteria. These conditions may not be relevant to every project nor are they replecated by other manufacturers.
  6. Maximum permissible shear stress has been obtained through unvegetated (30% to 70% density) testing programs featuring specific soil types, vegetation classes, flow conditions and failure criteria. These conditions may not be relevant to every project nor are they replecated by other manufacturers.
  7. Maximum permissible shear stress has been obtained through unvegetated (0% to 30% density) testing programs featuring specific soil types, vegetation classes, flow conditions and failure criteria. These conditions may not be relevant to every project nor are they replecated by other manufacturers.
