1.1 This test method covers the static determination of turbidity in water (see 4.1).<\/p>\n
1.2 This test method is applicable to the measurement of turbidities under 5.0 nephelometric turbidity units (NTU).<\/p>\n
1.3 This test method was tested on municipal drinking water, ultra-pure water and low turbidity samples. It is the user’s responsibility to ensure the validity of this test method for waters of untested matrices.<\/p>\n
1.4 This test method uses calibration standards are defined in NTU values, but other assigned turbidity units are assumed to be equivalent.<\/p>\n
1.5 This test method assigns traceable reporting units to the type of respective technology that was used to perform the measurement. Units are numerically equivalent with respect to the calibration standard. For example, a 1.0 NTU formazin standard is also equal to a 1.0 FNU standard, a 1.0 FNRU standard and so forth.<\/p>\n
1.6 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. Refer to the MSDSs for all chemicals used in this procedure.<\/span><\/span><\/p>\n D6855-10 Standard Test Method for Determination of Turbidity Below 5 NTU in Static Mode<\/b><\/p>\nPDF Catalog<\/h4>\n
