Large-scale performance property testing

Large-scale performance tests have been developed to simulate expected field conditions to report performance properties of as-instaUed ECPs and SRDs. Standardized, large-scale tests have been developed for slope and channel erosion, as well as for several sediment retention applications. Products are installed per the product manufacturer s published installation recommendations. The results of these tests indicate actual field performance and are acceptable for use in performance specifications and often in design calculations. 

The reader is referred to Ref 1 for a voluminous compilation of detonation properties (detonation velocity and diameter effect, cylinder test performance, plate dent test and detonation failure thickness), shock initiation properties (wedge test data and small and large - scale gap tests), and sensitivity tests (skid test, large-scale drop test or spigot test and spark sensitivity) relevant to LASL research expls Refs 1) T.R.

Often it is very difficult to determine the burning behavior of complex objects on the basis of the performance of its individual components in bench-scale reaction-to-fire tests. It is much more practical to measure the heat release rate and related properties for the complete object. This requires a large-scale test. In other cases, it is not possible to capture certain aspects of real fire behavior such as melting, delamination, joint effects, etc., in a bench-scale test. A large-scale test is needed to assess these effects. Two commonly used large-scale reaction-to-fire tests are test methods are discussed as follows.
