The organic peroxide in its commercial package is placed in the test chamber. A constant temperature air environment is maintained for seven days. If self-accelerating decomposition does not occur, the test is repeated at a higher temperature. Sufficient tests are made to determine an air temperature at which the package survives and an air temperature at which the sample undergoes autoaccelerative decomposition and damages the package where the temperature difference is not greater than 6 °C.

Constant Volume Sampler(CVS). Motor vehicle exhaust is a complex mixture of unburned fuel, combustion products(including a high water vapor content), and intake air that exits the tail pipe at high temperatures. In simulated driving conditions on the dynamometer, the volume of the exhaust emitted from the tail pipe is continually changing depending on where in the driving cycle the vehicle is(for example, during acceleration, during deceleration, at constant speed, or at idle). To quantitatively determine emission rates from vehicles, we use a constant volume sampling system, which maintains a constant total flow rate of vehicle exhaust plus dilution air. With a CVS system, as exhaust flow increases, such as during heavy acceleration, the dilution air is automatically decreased and the sampling source is representative of exhaust variations. This CVS system provides the source for all exhaust samples collected(regulated and unregulated). Because some compounds present in the exhaust are soluble in water, quantitative transfer requires that the diluted exhaust be maintained above its dew point by providing sufficient dilution air through the CVS. In addition, sampling components, such as the raw exhaust transfer duct and sample lines, must be heated to prevent water condensation.  2, record 23, English, - constant%20volume%20sampling

coefficient of haze(COH)(in atmospheric chemistry) : One technique of measurement of the amount of filterable particulate matter suspended in air which has been used in the past depends upon drawing a measured sample of air(usually 1 000 linear feet) through a paper or membrane filter. A measurement is made of the intensity of light transmitted through the dust spot formed relative to that transmitted through an identical clean filter. The dirtiness of the air is reported in terms of the COH unit. This relates to the quantity of particulate material which produces an optical density, lg(I 0/I) of 0. 01 when measured by light transmission at 400 nm and relative to the transmission of an identical dust-free filter taken as 100%. Thus a filter which transmitted 50% relative to the clean filter has an absorbance of 0. 301 or 30. 1 COH units. This is not a recommended measure of filterable particulate matter since the size, colour and other properties of the aerosol and the air in which it is suspended affect the results.

In meteorology, the condition existing in a given portion of the atmosphere (or other space) when the relative humidity is greater than 100 per cent, that is, when it contains more water vapor than is needed to produce saturation with respect to a plane surface of pure water or pure ice.  2, record 27, English, - supersaturation

Record number: 27, Textual support number: 1 OBS

Such supersaturation does develop because frequently there is no "plane surface of pure water (or ice)" available. In the absence of water surfaces and in the absence of condensation nuclei or any wettable surfaces, phase change from vapor to liquid cannot occur due to the free energy barrier imposed by the surface free energy of the embryonic droplets which would then have to form by spontaneous nucleation... Cloud condensation occurs in our atmosphere at relative humidities near 100 per cent only because nature provides an abundance of condensation nuclei.  2, record 27, English, - supersaturation

His air-flow planimeter consisted of two identically perforated plates mounted on an air-tight drum which was connected to a blower. The air pressure of the drum was determined when the sample plate was uncovered, leaves were placed on the plate and the reference plate was then uncovered sufficiently to return to the original air pressure.

The organic peroxide in its commercial package is placed in the test chamber. A constant temperature air environment is maintained for seven days. If self-accelerating decomposition does not occur, the test is repeated at a higher temperature. Sufficient tests are made to determine an air temperature at which the package survives and an air temperature at which the sample undergoes autoaccelerative decomposition and damages the package where the temperature difference is not greater than 6 [degrees) C.

Le plus souvent une vanne d'introduction comprend deux circuits gazeux distincts et un volume appelé "boucle d'échantillonnage" qui fait partie de l'un ou l'autre circuit, selon que la partie mobile de la vanne est dans l'une ou l'autre position : elle peut généralement être considérée comme constituant le point d'échantillonnage d'une installation d'analyse.

"High Volume Air Sampler": A filtering device for particulate collection, used by the National Air Pollution Control Administration to determine the concentrations of suspended particulates in American urban and rural areas. A glass-fiber medium is used which can filter at the rate of 70 cubic feet per minute. The filter is over 99 percent efficient for the collection of particles as fine as 0.3 um [micrometers] in diameter. High Volume Air Samplers generally run as long as 24 hours without an appreciable increase in airflow resistance.  1, record 52, English, - high%20volume%20air%20sampler

An instrument developed by John Aitken for determining the dust content of the atmosphere. In operation, a sample of air is mixed, in an expandable chamber, with a larger volume of dust-free air containing water vapor. Upon a sudden expansion, the chamber cools adiabatically below its dewpoint, and droplets form with the dust particles as nuclei(Aitken nuclei). A portion of these droplets settle on a ruled plate in the instrument and are counted with the aid of a microscope.  1, record 53, English, - Aitken%20dust%2Dcounter

Acoustic microscopy is the term applied to high resolution, high frequency ultrasonic inspection techniques which produce images of features beneath the surface of a sample. Because ultrasonic energy requires continuity of materials to propagate, internal defects such as voids, delaminations and cracks interfere with the transmission and/or reflection of ultrasound signals. Since air is a very poor conductor of ultrasound, gaps within or between samples are easily visualized by the localized changes in the ultrasound.  1, record 54, English, - acoustic%20microscopy

Filter Sampling. Filter material impregnated with reagents for specific gases can be used for atmospheric sampling. One of the more common techniques of this kind is the paper tape sampler. A roll of paper tape is impregnated and dried. The tape is then placed in a mechanical unit which sequences a tape section into position for sampling. After a known volume of air has been drawn through it, the tape is removed and the sample analyzed.  3, record 55, English, - tape%20sampler
