19、r Toxic Gas Detectors. It is the second edition of ANSI/ISA-92.00.01 and the second edition of ANSI/UL 920001. The document is a modification of the ISA document to create the equivalent UL version and maintain the ANSI approval of this standard. ANSI/ISA-92.00.01 and ANSI/UL 920001 contain identica
20、l requirements, and identical publication dates. Efforts have been made to synchronize the UL edition number with that of the corresponding ISA standard with which this standard is harmonized. As a result, one or more UL edition numbers have been skipped to match that of the ISA edition number. This
21、 common standard was prepared by the (ISA) - The International Society of Automation on December 23, 2010 but is now being maintained by Underwriters Laboratories Inc. (UL). Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remai
22、ns the responsibility of the users of the standard to judge its suitability for their particular purpose. UL Effective Date The requirements in this standard are in effect. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard. This pa

This document has been prepared as part of the service of
24、 ISA towards a goal of uniformity in the field of instrumentation. To be of real value, this document should not be static but should be subject to periodic review. Toward this end, the Society welcomes all comments and criticisms and asks that they be addressed to the Secretary, Standards and Pract

The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the Inte
26、rnational System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their business and professional dealings with other c
27、ountries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible.

41、December 23, 2010 NOTE This means that other relevant requirements (e.g. hazardous (classified) locations, environmental ratings, combustible gas detection, cross-sensitivity poisoning, etc.) must be addressed. 4.1.2 All toxic gas-detection apparatus shall meet the minimum construction and test requ
42、irements contained within this standard. When verifying a manufacturers claimed superior performance or special features of construction, the minimum requirements of the standard must be met and the manufacturers claimed superior performance must be verified by test. The superior performance of one
43、criterion may result in a reduced performance in other criteria. The additional tests should be agreed upon by the manufacturer and test laboratory and identified and described in the test report. EXAMPLES: (1) When a manufacturer claims a sensor accuracy over a defined temperature range of 50C to +
44、40C at 10ppm (assuming a measuring range of 0-100ppm), the sensor shall meet the manufacturers claim from 50C to 10C and meet the specified requirements of section 5.15 for the temperature range of 10C to +40C. (2) For detectors that consist of detection and alarm capabilities for simultaneous detec
45、tion of 5 or more gases, the product shall state the following, “Reference instruction manual for a list of all gases. The additional tests shall be agreed between the manufacturer and test laboratory. 4.1.3 Gas-detection apparatus, their components, and remote detector heads specifically intended f
46、or use in the presence of corrosive vapors or gases shall be constructed of materials resistant to, or protected against, corrosion. 4.1.4 Apparatus of the sample-draw type shall include the necessary sample-pumping mechanisms. 4.2 Indicating devices (audible, visual and display) 4.2.1 An indication
47、 shall be provided to show that the apparatus is energized. NOTE For fixed apparatus the indication may be shown at the control unit. 4.2.2 For alarm-only apparatus or apparatus where the resolution of the read-out device is inadequate to demonstrate compliance with this standard, the manufacturer s
48、hall identify suitable points for connecting indicating or recording devices for the purpose of testing the compliance of the apparatus with this standard. The indication on the readout device shall not contradict the results obtained by additional indicating or recording devices. NOTE - If the main
49、 mode of the apparatus is “alarm only”, but through a special or factory provided mode can display the gas reading in sufficient resolution, the special or factory mode may be used to determine compliance with agreement between the Testing Laboratory and Manufacturer. 4.2.3 Any under-range or over-range measurements shall be clearly indicated. 4.2.4 The audible and visual alarm settings for the apparatus shall not be ambiguous. If the apparatus has more than one measuring range per gi
