Abstract:
The precision of for leaching tests, published as the Dutch standards NEN7341 (Availability Test), NEN 7343 (Column Test), NEN 7345 (Diffusion Test),
and NEN 7349 (Cascade Test), is determined in terms of repeatability and
reproducibility, according to the NEN-ISO 5725 standard. Use has been made of
a round-robin test among 10 laboratories, which analyzed 6 different types of
materials: waste incinerator fly ash, pulverized coal bottom ash, waste
incinerator bottom ash, fly ash/cement stabilization, calcareous sandstone
and E-fly ash, and building bricks. The chemical analyses are carried out for
each leaching test by one laboratory in order to reduce the analytical errors
in the test results as much as possible. 14 figs., 17 tabs., 4 appendices, 8
refs.
