This comprehensive manual includes information on clear water repellent materials for both vertical and horizontal surfaces. Also included are a glossary, product comparisons, specifications, monograph and performance test criteria.
5.1 The presence of water-soluble extractables in membrane filters can create errors in test procedures employing membrane filters. However, these errors can be eliminated or significantly reduced if the quantity of water-soluble extractables of the...
1.1 This test method covers a membrane filter (MF) procedure for the detection and enumeration of the enterococci bacteria in water. The enterococci, which include Entero-coccus faecalis (E. faecalis), E. faecium, and their varieties are commonly found in the feces of humans...

5.1 Microbiological water testing procedures using membrane filtration are based on the premise that all bacteria within a specific size range will be retained by the membrane filter used. If the membrane filter does not retain these bacteria, false...
5.1 Cryo-TEM is a technique used to record high resolution images of samples that are frozen and embedded in a thin layer of vitrified, amorphous ice (2-5). Because vitrification occurs so rapidly, the resultant specimen is almost instantly frozen, yielding a very accurate representation of the...
General This standard describes two methods for evaluating water quality for subsurface injection: Procedure A-rate versus cumulative volume test (for water-quality monitoring) and Procedure B-suspended solids test (for diagnosis or monitoring). The methods describe the apparatus...
1.1 This test method covers the operation, calibration, and data interpretation for an on-line corrosion product (metals) monitoring system. The monitoring system is based on x-ray fluorescence (XRF) analysis of metals contained on membrane filters (for suspended solids) or resin...
This test method describes a membrane filter (MF) procedure for the detection and enumeration of Escherichia coli, a bacterium found exclusively in the feces of humans and other warm-blooded animals. The presence of these microorganisms in water is an indication of fecal...

1.1 This test method covers determination of the dry filterability of lubricants and hydraulic fluids based upon mass flow rate measurements through a 0.8?μm membrane after ageing (Note 1). The procedure applies to lubricants and hydraulic fluids that are formulated with American...
