19、ISSION FROM UL1 ANSI/ISA-12.12.03-2011 (R2015) ANSI/UL 121203 December 14, 2015 General Notes This is the common ISA and UL, Standard for Portable Electronic Products Suitable for Use in Class I and II, Division 2, Class I, Zone 2 and Class III, Division 1 and 2 Hazardous (Classified) Locations. It

20、is the first edition of ANSI/ISA-12.12.03 and the first edition of ANSI/UL 121203. 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-12.12.03 and ANSI/UL 121203 contain identical requirements, and identica

21、l publication dates. This common standard was prepared by the (ISA) - The International Society of Automation on June 28, 2011 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

22、to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose.

23、reface (ISA) This preface, as well as all footnotes and annexes, is included for information purposes and is not part of ANSI/ISA-12.12.03-2011 (R2015). This document has been prepared as part of the service of ISA toward a goal of uniformity in the field of instrumentation. To be of real value, thi

24、s document should not be static but should be subject to periodic review. The ISA Standards and Practices Department is aware of the growing need for attention to the metric system of units in general, and the International System of Units (SI) in particular, in the preparation of instrumentation st

25、andards. 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 countries. Toward this end, this Department will endeavour to introduce SI-acceptable m

26、etric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible.

28、isted for use in the location or b) Any product when a suitable work permit is in effect; see Note 2 of 4.2 NOTE 1 In the United States, an OSHA interpretation of 29CFR1910.399 requires that a listed product be used if it is available. Examples of available listed products include pagers, flashlight

29、s, and some test instruments. NOTE 2 The application of PEP 1 and PEP 2 products in a hazardous (classified) location assumes that personnel will take the product with them when they vacate the area. NOTE 3 Text referring to Class I Division 1 and Class II Division 1 although outside the scope is pr

30、ovided for information only. 6 Portable Electronic Products (PEPs) 6.1 General PEP shall meet the following criteria: a) No available listed apparatus suitable for the area classification and capable of performing the intended function b) Radio frequency energy transmission limited in accordance wit

31、h 8.3 c) No provisions for forced ventilation d) No sparks visible in normal operation e) No excessive temperatures in normal operation f) No camera flash unless it can be disabled g) No motors unless it can be demonstrated the motor incorporates non-arcing technology UL COPYRIGHTED MATERIAL NOT AUT

33、 a maximum of two button cells b) Body-worn and in direct contact with the skin c) No electrical connections accessible outside the product Examples are electronic wristwatches and hearing aids that are inserted into the ears. 6.3 PEP 2 Products meeting the general criteria in 6.1 and all of the fol

34、lowing additional criteria may be designated as PEP 2: a) Powered by one or more cells, batteries, or photovoltaic cells b) Cell or battery secured so it will not fall out in the drop test as described of 8.1 c) Body-worn or hand-held d) No external electrical connections or wired accessories are us

35、ed in the hazardous (classified) location. NOTE Bluetooth headset is an example of a non-wired accessory. e) Exposed terminals (for example battery charging terminals) are either recessed or diode protected to prevent a discharge caused by an accidental shorting of these terminals. f) Power switch i

36、n accordance with 8.2 g) No damage that exposes the electrical/electronic circuitry as a result of the drop test described in 8.1 Examples are some calculators, some medical injection devices, electronic watches with calculators and some cell phones. 7 Administrative controls 7.1 General A process o

37、f administrative control and training is necessary to ensure that portable products do not present an unacceptable risk of ignition when used in hazardous classified areas. 7.2 PEP 1 and PEP 2 The owner/operator of the hazardous (classified) location should establish a process of inspection in which

38、 a qualified person establishes that particular products can be accepted as PEP 1 or PEP 2. For PEP 1, products can be accepted without additional marking. For PEP 2, all accepted products should be marked in accordance with Clause 9. UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION O

39、R DISTRIBUTION WITHOUT PERMISSION FROM UL15 ANSI/ISA-12.12.03-2011 (R2015) ANSI/UL 121203 June 28, 2011 Supporting documentation for the PEP evaluations should be maintained for the life of the use of those products. This documentation should include information for the product such as reference num

40、ber or code, product manufacturer and model, owner name, approver name, and date approved or equivalent information. NOTE The supporting documentation reference number or code may be a serial number, an approver generated tag number or other means of unique identification to provide tracking with th

41、e documentation. 7.3 Safe/Hot Work Permit 7.3.1 Gas Free Work Permit A Gas Free Work Permit should incorporate the following: a) A measurement to confirm the absence of an ignitible concentration of any flammable gas or vapor b) Sampling to confirm the continued absence of a flammable gas or vapor c

42、) Contingency plans for emergencies Annex A provides an example of a Gas Free Work Permit process that incorporates these requirements and restrictions. 7.3.2 Dust Free Work Permit A similar concept to the Gas Free Work Permit may also be applied to areas with combustible dusts or ignitible fibers a

43、lthough measurement and sampling are not required. Visual analysis is usually sufficient. 8 Examination and testing 8.1 Drop test For PEP 2, the product shall be able to pass a drop test. The product (or a sample of the product) in the form in which it is intended to be used, shall be dropped onto a

44、 horizontal concrete surface from a height of 2 meters (6 feet 6 inches). The test is repeated six times with the device being dropped in the six orientations that are considered most likely to cause a failure. At the conclusion of the testing, the integrity of the enclosure shall not have been comp

45、romised, the cell or battery shall not have fallen out or become disconnected, and the device shall operate as intended. NOTE If the product is intended to be used only while in a case and the case affords protection to the battery, then the drop test is done with the product in its case. For exampl

46、e, a cell phone with a Bluetooth headset. If the product is intended to be used after the product is removed from its case, then the drop test is performed with the product removed from its case, for example, a cell phone in a body-worn holster that will be removed from the holster to use the phone.

47、 8.2 Power on-off switches Any product with a power on-off switch with contacts that directly interrupt battery current is not acceptable for PEP 2 because the switch may cause an ignition-capable arc. NOTE If the switch operator is not a maintained position device and requires the same action for o

48、n and off, then it is likely to be an electronic switch. Generally electronic products use the electronic circuit type of switch. 8.3 Radio frequency energy The radiated radio frequency (9 kHz to 60 GHz) energy from a product, such as a radio or cell phone, is not considered an ignition source if th

49、e power is equal to or below the following limits. If the power is above these limits, the 7.3 Safe/Hot Work Permit shall be used.
