1.1 These test methods cover the determination of ammonia nitrogen, exclusive of organic nitrogen, in water. Two test methods are included as follows:

Section Test Method A-Direct Nesslerization ...

1.1 This test method covers the determination of resonances unpackaged products and components by means of horizontal linear sinusoidal motion applied at the surface on which the product is mounted. For vertical vibration testing of products see Method D3580. Two alternate test methods are presen...

Simple and complex fluoride ions are found in natural waters. Fluoride forms complexing ions with silicon, aluminum, and boron. These complexes may originate from the use of fluorine compounds by industry.

Fluoridation of drinking water to prevent dental caries is practiced by a large nu...

1.1 These test methods cover the determination of relative permittivity, dissipation factor, loss index, power factor, phase angle, and loss angle of specimens of solid electrical insulating materials when the standards used are lumped impedances. The frequency range that can be covered extends f...

1.1 This test method describes the determination of plutonium in solutions of unirradiated nuclear-grade (that is, high-purity) materials by controlled-potential coulometry. Controlled-potential coulometry may be performed in a choice of supporting electrolytes, such as 0.9 HNO 3 , 1 H...
