low-temperature properties
21Negative temperature coefficient — A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material rises with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will decrease with increasing… …
22Homologous temperature — expresses the temperature of a material as a fraction of its melting point temperature using the Kelvin scale. For example, the homologous temperature of lead at room temperature is approximately .50 (TH = T/Tmp = 298K/601K = .50).Solder (m.pt… …
23Color temperature — The CIE 1931 x,y chromaticity space, also showing the chromaticities of black body light sources of various temperatures (Planckian locus), and lines of constant correlated color temperature. Color temperature is a characteristic of visible light …
24Ultra-low-sulfur diesel — (ULSD, also spelled “sulphur” in British English) is a term used to describe diesel fuel with substantially lowered sulfur content. As of 2006, almost all of the petroleum based diesel fuel available in Europe and North America is of a ULSD type …
25Cross-linked polyethylene — PEX redirects here. For other uses, see Pex (disambiguation). Cross linked polyethylene, commonly abbreviated PEX or XLPE, is a form of polyethylene with cross links. It is formed into tubing, and is used predominantly in hydronic radiant heating …
