The manual, auto-initiated, and demand-initiated regeneration (DIR) residential cation exchange water softeners addressed by this Standard are designed for the reduction of specific substances that may be present in drinking water (public or private) considered to be...
Many paper mill boilers operate with softened water as the primary feedwater makeup source. The guidelines applicable to water treatment programs for paper mill boilers with softened water makeup are provided. Monitoring and sampling procedures to assure maximum...
This European Standard specifies requirements relating to the construction and mode of operation and relevant methods of testing of automatic, salt-regenerated, cation exchange softeners for drinking water installations inside buildings which are permanently connected to the mains...

This standard specifies the requirements for a grade of calcium hydroxide (hydrated lime) suitable for use in water-softening plant and for the treatment of effluent and acid waste.
Pitch does not go through a solid-liquid phase change when heated, and therefore it does not have a true melting point. As the temperature rises, pitch softens and becomes less viscous. The softening point is arbitrarily defined and shall be established by a closely controlled method...
1.1 This test method covers the determination of the softening point of pitches below 176°F (80°C) by this method. Pitches of higher softening point should be tested by Test Method D2319 or Test Method D3104. 1.2 This standard does not purport to address all of the safety...

This test method covers the determination of the softening point of pitches below 176 °F (80 °C). Pitches of higher softening point should be tested by Test Method D2319 or Test Method D3104. The values stated in inch-pound units are to be regarded as standard. The values given in...
