Standard Test Method for Ash and Organic Matter Content of Degradable Erosion Control Products

Importancia y uso:

5.1 The ash content of the degradable ECP may consist of various residues from chemicals used in its manufacture, metallic matter from piping and machinery, mineral matter in the ECP fibers from which the degradable ECP was made, and filling, coating, pigmenting or other added materials. The amount and composition of the ash is a function of the presence or absence of any of these materials or others singly or in combination. No specific qualitative meaning is attached to the term “ash” as used in this test method.

5.2 In most cases, the ash content of ECPs will contain inorganic residues from the ECP fibers, inorganic residues from any added chemicals, and loading or filling materials deliberately added.

5.3 For ECP fibers containing cellulose and clays, or materials having variable chemical composition, variable thermal decomposition behavior, or both, the ash level may necessitate significant confirmation regarding the materials added.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors
