Gas Sensor Standards

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 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...

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...

008640-000000-000000 1 Scope 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)...

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,...

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...

002680-000000-000000 1 Scope 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;...

629900-000010-000000 1 Scope 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...

013370-000000-000000 1 Scope 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...

1.1 This test method, commonly referred to as the Cummins ISB Test, covers the utilization of a modern, 5.9?L, diesel engine equipped with exhaust gas recirculation and is used to evaluate oil performance with regard to valve-train wear. 1.2 The values stated in SI units are to be regarded...

013370-000000-000000 1 Scope 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...

1.1 This test method covers a procedure for determination of the transmission rate of oxygen gas through plastics in the form of film, sheeting, laminates, coextrusions, coated or uncoated papers or fabrics. 1.2 This test method is not the only method for measurement of the oxygen...

1.1 This practice covers the minimum requirements for an in-line, non-intrusive, through-flow oil debris monitoring system that monitors ferromagnetic and non-ferromagnetic metallic wear debris from both industrial aero-derivative and aircraft gas turbine engine bearings. Gas turbine...
