ASTM D6303-98<\/h3>\n

Withdrawn Standard: Standard Test Method for Formaldehyde in Water (Withdrawn 2007)<\/h4>\n
\n

ASTM D6303<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method covers the determination of the formaldehyde monomer concentration in water and wastewater.<\/p>\n

1.2 This test method is suitable for free formaldehyde concentrations in the range of 0.2 to 7.0 mg\/L. For samples containing concentrations greater than 7 mg\/L, dilute with reagent water prior to analysis. Samples containing between 0.02 and 0.5 mg\/L may be run using a 10-cm cell.<\/p>\n

1.3 This test method is for use with reagent water and wastewater. It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices.<\/p>\n

1.4 Formaldehyde polymers react partially or slowly, or both, making this test method unsuitable for analysis of these compounds.<\/p>\n

1.5 For specific hazard statements, see Section 9. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/p>\n
