1、Designation: D5905 98 (Reapproved 2013)Standard Practice forthe Preparation of Substitute Wastewater1This standard is issued under the fixed designation D5905; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisi

2、on. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the preparation of an aqueousmixture containing constituents in concentrations such that itwill have physica

3、l and chemical matrix characteristics similarto municipal wastewater.1.2 Wastewaters are extremely variable, depending on thequantity and nature of the materials being discharged into thecollection system. The mixture prepared with this practice isnot representative of any particular wastewater. Rat

It allows the evalu-ation of test methods, over time, against the same referencepo

5、int.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish

Significance and Use4.1 Substitute wastewater may be used for laboratory testingwhere a reproducible mixture simulating municipal wastewateris required. To provide a more rugged evaluation of a testm

9、ethods ability to measure analytes and the precision of thetest method under more demanding conditions, it is necessaryto utilize a matrix more complex than reagent water. Substitutewastewater is intended to be used as a material to be spikedwith analytes or interferents of interest to evaluate the

10、perfor-mance of test methods.4.2 Utilization of substitute wastewater as a matrix ininterlaboratory validation studies will allow inclusion of per-formance statistics for this matrix in the Precision and Biassection of test methods. Users of test methods will be able toevaluate their application of
