Over the past two and one-half decades several metal clad fibers and fabrics have been developed to provide aerospace vehicle designers with a conductive, lighter weight alternative to coated copper, coated stainless steel and steel wire used for cable and wire shielding and harness overbraids on...
1.1 This classification system covers liquid crystal polymeric (LCP) materials suitable for injection molding and extrusion. This classification system allows the use of liquid crystal polymers that are recycled, reconstituted, recycled-regrind, recovered, or reprocessed, or a...
5.1 The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals. These crystals can restrict the flow of fuel through the fuel system of the aircraft. The temperature of the fuel in the aircraft tank normally decreases...
4.1 PFAS are widely used in commercial and industrial applications worldwide (see Fig. 1). PFAS are of concern due to their documented persistence and their studied impacts on human health and the environmental. While there is no comprehensive source of information on the many individual PFAS...
1.1 This classification covers refractory products consisting predominantly of mullite (3Al2O3·2SiO2) crystals that are formed by either converting any of the sillimanite group of minerals, or synthesizing from appropriate materials in a melt or sinter process. 1.2 The values stated in...
1.1 This test method covers the determination of total oil and grease, and total petroleum hydrocarbons in produced water and wastewater by an infrared (IR) determination of n-hexane extractable substances from the sample. Included in this estimation of total oil and grease are any other compounds...

This specification covers the requirements and test methods for direct-reading liquid crystal forehead thermometers, in either the continuous or intermittent reading modes, designed to monitor trends or measure human forehead surface temperatures, or both. When examined by test methods...
5.1 The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals which, if present in the fuel system of the aircraft, can restrict the flow of fuel through filters. The temperature of the fuel in the aircraft tank normally...

This specification covers the requirements for pressure and differential pressure transducers for general applications. Pressure transducers typically consist of a sensing element that is in contact with the process medium and a transduction element that modifies the signal from the sensing element...
5.1 This practice may be applied when tristimulus colorimeters are used to measure the colors produced on self-luminous video display devices such as CRTs and flat-panel displays, including electroluminescent (EL) panels, light emitting diodes (LEDs) field emission displays (FEDs), and back-lit...
3.1 These practices are useful for determining the maximum temperature at which crystallization will form in a glass, and a minimum temperature at which a glass can be held, for extended periods of time, without crystal formation and growth.
5.1 The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals which, if present in the fuel system of the aircraft, can restrict the flow of fuel through filters. The temperature of the fuel in the aircraft tank normally...
This test method covers a technique for generating data to characterize the kinetics of the release of outgassing products from spacecraft materials. This technique will determine both the total mass flux evolved by a material when exposed to a vacuum environment and the deposition of this flux on...
4.1 General-Ultrasonic testing is a widely used nondestructive method for the examination of a material. The majority of ultrasonic examinations are performed using transducers that directly convert electrical energy into acoustic energy through the use of piezoelectric crystals. This guide...
5.1 The wax appearance temperature of petroleum products and liquid fuels is an indicator of the lowest temperature of their utility for certain applications. Wax crystals of sufficient quantity can plug filters or impede flow in some fuel systems. 5.2 The wax disappearance temperature of...
4.1 This guidance document describes the components and conditions used for in vitro osteoblast differentiation assays that can be used to screen for the osteogenic capability of progenitor stem cells from various human or animal sources, including mixed tissue-derived connective tissue progenitor...
