| S value | Svedberg Unit. See: sedimentation coefficient. (18 Nov 1997) |

| iodine value | An indication of the quantity of unsaturated fatty acids present in a fat; it represents the number of grams of iodine absorbed by each 100 g of fat. See: hydrogen number. Synonym: iodine value. (05 Mar 2000) |
| tenth-value layer | <radiobiology> Thickness of a specified substance which, when introduced into the path of a given beam of radiation, reduces the absorbed dose index or dose-equivalent index to one-tenth. The magnitude of the tenth-value layer may be different for absorbed dose index and dose equivalent index. (16 Dec 1997) |
| thiocyanogen value | The number of grams of thiocyanogen taken up by 100 g of fat; analogous to the iodine number, except that thiocyanogen will not add to all the double bonds in polyunsaturated fatty acids as will iodine. Synonym: thiocyanogen value. (05 Mar 2000) |
| threshold limit value | The maximum concentration of a chemical recommended by the American Conference of Government Industrial Hygienists for repeated exposure without adverse health effects on workers. (05 Mar 2000) |
| economic value of life | The evaluation of the monetary value of a life lost or a life saved. (12 Dec 1998) |
| law of initial value | The direction of response of a body function to any agent depends to a large degree on the initial level of that function. Synonym: law of initial value. (05 Mar 2000) |
| lower heating value | (LHV) The potential energy in a fuel if the water vapour from combustion of hydrogen is not condensed. (05 Dec 1998) |
| abbreviated injury scale | Classification system for assessing impact injury severity developed and published by the american association for automotive medicine. It is the system of choice for coding single injuries and is the foundation for methods assessing multiple injuries or for assessing cumulative effects of more than one injury. These include maximum ais (mais), injury severity score (iss), and probability of death score (pods). (12 Dec 1998) |
| absolute scale | An obsolete term for Kelvin scale. (05 Mar 2000) |
| activities of daily living scale | A scale to score physical activity and its limitations, based on answers to simple questions about mobility, self-care, grooming, etc; widely used in geriatrics, rheumatology, etc. (05 Mar 2000) |
| Angstrom scale | A table of wavelengths of a large number of light rays corresponding to as many Fraunhofer's lines in the spectrum. (05 Mar 2000) |
| Baume scale | A hydrometer scale for determining the specific gravity of liquids heavier and lighter than water, respectively: for liquids lighter than water, divide 140 by 130 plus the Baume degree; for liquids heavier than water, divide 145 by 145 minus the Baume degree. (05 Mar 2000) |
| Binet scale | A measure of intelligence designed for both children and adults. (05 Mar 2000) |
| Binet-Simon scale | Forerunner of individual intelligence tests, particularly the Stanford-Binet intelligence scale, and sometimes referred to as the Binet scale. (05 Mar 2000) |
