This specification covers engineered wood fiber for use as a playground safety surface under and around playground equipment. This specification establishes minimum requirements for the factors that determine particle size, consistency, purity, ability to drain, and heavy metal concentrations considered hazardous to children. This specification does not imply that an injury cannot be incurred if the engineered wood fiber complies with this specification. The performance requirements for (1) sieve test analysis, (2) hazardous metal test (for antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium), and (3) magnetic and nonmagnetic tramp metal tests are specified. The sieve test apparatus shall include balances, sieves, sieve shaker, and oven. The test apparatus for hazardous metal test shall include metal sieve, pH, membrane filter, reagents, hydrochloric acid solution, Type 3 water, centrifuge, and container. The test apparatus for magnetic tramp metal test shall be an industrial grade magnetic wand with a cylindrical neodymium iron-boron rare earth magnet at the end of the probe. A schematic diagram of the magnetic probe is provided. The sampling method, sample test preparation, test procedure, and test report for the three test methods are detailed.
