Introduction and Summary Gasoline marketing in this country has undergone significant changes in the last 15 years. In response to these changes, some dealers and other market participants have called for the enactment of divorcement and open supply legislation at both the state and federal levels....
This Spotlight discusses optical sensing strategies and applications for early diagnostics in exhaled-breath (EB) analyses. These sensors can noninvasively assess relevant biomarkers in EB, enabling early diagnosis of several diseases (e.g., cancer, asthma, diabetes) and the monitoring of...
This part of IEC 62899 specifies mechanical and thermal test methods for the determination of the reliability characteristics of a printed flexible gas sensor, which is operated at relatively low temperature and is composed of a flexible substrate, electrode, and gas sensing...
Inventories of Natural Gas Liquids and Liquefied Refinery Gases presents data on the inventory levels of ethane, propane, isobutane, normal butane and pentanes plus. These inventories, located at natural gas plants, refineries, bulk terminals and in underground storage, are...
1.1 This Standard covers requirements as related to the following: a) Discrete electrical control units and accessories for fire alarm systems including smoke control, releasing, Building System Information Unit (BSIU), and emergency communication systems; b) Electrically- and...
5.1 These measurements give semiquantitative estimates for the gas transmission of single pure gases through film and sheeting. Correlation of measured values with any given use, such as packaged contents protection, must be determined by experience. The gas transmission rate...
1.1 This practice establishes standardized tests for the performance evaluation of sensor-based continuous instruments for ambient outdoor air quality measurements. It describes both laboratory and field tests that provide information on candidate sensor repeatability, sensitivity,...
This part of ISO 12614 specifies tests and requirements for the gas temperature sensor, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISO 3833. This part of ISO 12614 is not applicable to the following: a) fuel...
1.1 This Standard sets forth requirements for smoke detectors and accessories, including mechanical guards to be employed in ordinary indoor locations in accordance with the following: a) In Canada only: 1) Standard for the Installation of Fire Alarm Systems, ULC-S524; 2) National Building Code of...
This part of ISO/IEC 62990 specifies general requirements for design, function and performance, and describes the test methods that apply to portable, transportable, and fixed equipment for the detection and concentration measurement of toxic gases and vapours in workplace atmospheres and...
Applies to gas analyzers using high temperature electrochemical sensors for measurement of oxygen in gas. Applies to both 'in situ' and extractive analyzers installed indoors or outdoors.
1.1 This standard sets forth minimum requirements for the following types of devices for engine fuel system applications intended for use with liquefied petroleum gas (LP-Gas), natural gas, and/or manufactured gas. a) Automatic shutoff valves - electrically operated or...
1.1 This standard sets forth minimum requirements for the following types of devices for engine fuel system applications intended for use with liquefied petroleum gas (LP-Gas), natural gas, and/or manufactured gas. a) Automatic shutoff valves - electrically operated or...
AIR5933 provides an overview of contemporary technologies (i.e., sensors) that measure the proportion of oxygen in a gas. The use of these sensors in the aerospace environment, with its special constraints, is discussed and papers/reports with detailed information are...
