    ATIS 0600010-2007 Temperature Humidity & Altitude Standards.pdf

    1、 AMERICAN NATIONAL STANDARD FOR TELECOMMUNICATIONS ATIS-0600010.2014 TEMPERATURE, HUMIDITY, AND ALTITUDE REQUIREMENTS FOR NETWORK TELECOMMUNICATIONS EQUIPMENT UTILIZED IN CONTROLLED ENVIRONMENTAL SPACES As a leading technology and solutions development organization, ATIS brings together the top glob

    2、al ICT companies to advance the industrys most-pressing business priorities. Through ATIS committees and forums, nearly 200 companies address cloud services, device solutions, emergency services, M2M communications, cyber security, ehealth, network evolution, quality of service, billing support, ope

    3、rations, and more. These priorities follow a fast-track development lifecycle from design and innovation through solutions that include standards, specifications, requirements, business use cases, software toolkits, and interoperability testing. ATIS is accredited by the American National Standards

    4、Institute (ANSI). ATIS is the North American Organizational Partner for the 3rd Generation Partnership Project (3GPP), a founding Partner of oneM2M, a member and major U.S. contributor to the International Telecommunication Union (ITU) Radio and Telecommunications sectors, and a member of the Inter-

    5、American Telecommunication Commission (CITEL). For more information, visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consen

    6、sus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and obj

    7、ections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or us

    8、ing products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an interp

    9、retation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or

    10、withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or writing the American N

This defines the typical operating environments in which e

    22、quipment is deployed. Table 4.1: Temperature and Humidity Range of Operation Temperature Range Humidity Range Operating Short Term* Operating Short Term 5 to 40C (41 to 104 F) -5 to 50C (23 to 122F)5 to 85% RH 5 to 90% RH * Test requirements may be higher than the specified operating environment. AT

    23、IS-0600010.2014 3 4.2 Operating Altitude It is expected that network equipment may be routinely installed at elevations up to 1829 m (6,000 ft) above sea level. In some cases, network equipment may be installed at elevations up to 3962 m (13,000 ft) above sea level. At high elevations, the lower den

    24、sity of the air reduces its cooling capacity. Appropriate cooling capacity must therefore be provided. The high altitude environment is defined in Table 4.2. Table 4.2: Elevation and Temperature Range for High Altitude Environments Altitude (Above Sea Level) Maximum Operating Temperature* All Equipm

    25、ent 1829 m (6,000 ft) 50C (122F) Equipment intended for very high altitude installations 3962 m (13,000 ft) 40C (104F) * The test temperature may be higher than the specified operating environment. 4.3 Storage & Transportation Conditions Network equipment may be exposed to a variety of extreme tempe

    26、ratures and humidity while being transported or stored. The storage and transportation environments are defined in Table 4.3. Table 4.3: Temperature and Humidity Range for Storage and Transportation Environments Temperature Relative Humidity, % Low Temperature -40C (-40F) Not controlled High Tempera

    27、ture 70C (158F) Not controlled High Humidity 40C (104F) 95 5 Equipment Cooling Category Equipment cooling categorizations are defined based on the cooling media and methodology. 5.1.1 Natural or Free Convection Natural or free convection is heat transfer that relies on fluid motion caused by the dif

    28、ference in density of heated fluids and the action of gravity. Telecommunications equipment cooled by natural or free convection does not rely on fans, blowers, or pumps for cooling. 5.1.2 Forced Convection Forced convection is heat transfer that relies on powered means to cool a device. See ATIS-06

    29、00010.03, Heat Dissipation Requirements for Network Telecommunications Equipment, to determine airflow directions and designations. Any telecom equipment manufacturer should pictorially specify the location of the inlet air and exhaust air as it applies to each specific design in its intended enviro

    30、nment. For example, for a shelf that is to be deployed in a third-party rack, the manufacturer should designate the air inlet and exhausts with respect to the rack. ATIS-0600010.2014 4 5.1.3 Liquid Cooled Liquid cooling is expected to be at the component-level or frame-/cabinet-level, not at the roo

    31、m-level. For reasons of cost and feasibility, liquid cooling is not a preferred cooling method for telecom equipment and currently is not widespread. However, as the power densities grow, it is possible that in the future some elements of the network may have to use this technology to be able to acc

    32、ommodate the desirable speed, size, or capacity. Therefore, it is advisable that telecom industry and standard bodies look into various technologies and adopt some, so that manufacturers can move some designs to liquid cooling if needed. 6 Environmental Test Conditions 6.1 Temperatures & Humidity Th

    33、e baseline temperature and humidity test conditions for the EUT are shown in Table 6.1 covering variations in equipment configuration such as frame-level, shelf-level, and air intake designs. It is preferred that the air intake be at the front of the EUT. EUTs with air deflecting systems that bring

    34、the air in from the front are considered as front-air intake equipment and must be tested with these systems in place. For EUTs with other air-flow configurations, the maximum test temperature (TMAX) shall be raised by 10C as shown in Table 6.1. NOTE: These air deflecting systems become part of the

    35、EUT configuration and are subject to tests applicable for that configuration. Such air deflecting systems may also be subject to other mechanical tests as specified in the applicable ATIS standards.

    43、t of a single test chamber that is able to produce the exposure conditions described in this test procedure and have the following characteristics: To ensure proper airflow around the EUT, the volume of the test chamber should be at least five times the total volume of the EUT. The EUT should be kep

    44、t a minimum of 15.2 cm (6 in) from all chamber walls. The air flow in the test chamber should be less than 1 m/s (197 ft/min) near the EUT in order to prevent undue influence on the ventilation system of the EUT. This allows components inside the equipment to reach their working temperature during t

    45、he test in relation to the ambient conditions of the chamber. Chamber airflow velocity can be assessed prior to insertion of EUT. The test chamber shall control the temperature and humidity such that the specified rates of change can be obtained. ATIS-0600010.2014 6 Environmental chambers shall be c

    46、apable of controlling temperature within a tolerance of 3C, and humidity within a tolerance of 5% RH. Altitude chambers shall be capable of controlling temperature within a tolerance of 3C, and pressure within a tolerance of 3kPa while dwelling. For purposes of this standard, 80 kPa (600 torr) absol

    47、ute pressure will be equivalent to an altitude of 1829 m (6000 ft), and 60 kPa (450 torr) absolute will be equivalent to an altitude of 3962 m (13,000 ft). 7.2 Support Equipment The equipment should be appropriate for controlling, powering, or monitoring system performance for extended periods of ti

    48、me. 7.3 Sample Requirements All testing shall be performed on equipment that is representative of the equipment deployed. Actual production samples are not required. If testing is performed with pre-release hardware and product changes occur prior to release, the changes must be analyzed to determin

    49、e if they may reasonably impact the outcome of the tests. If a significant impact is indicated, the testing shall be repeated on released hardware. These simulations are “type tests” and are generally performed on a single equipment assembly or a single integrated system. For the purpose of this test, an equipment assembly is the smallest grouping of equipment sold by the manufacturer as a standalone piece of equipment. Equipment assemblies do not exceed 0.914 m (36”) in height. Equipment greater than 0.914 m (36
