This specification covers the design and dimensional requirements for the construction of standard and custom-built interior steel doors and frames intended for use in staterooms, lavatories, passageways, and other weather-protected areas of ships, including U.S. Coast Guard certificated vessels, with domestic routes. The doors and frames are to be of hollow metal construction with the door insulated for sound or fire. The doors and frames shall conform to the specified dimensional and construction procedures established for each class and type, which shall be indicated in the ordering information.1.1 This specification covers the construction of standard and custom-built interior steel doors and frames for ships including U.S. Coast Guard certificated vessels with domestic routes.1.2 Doors and frames are to be hollow metal construction with the door insulated for sound or fire.1.3 The doors are intended for use in staterooms, lavatories, passageways, and other areas protected from weather.1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 This practice is intended to serve as a guide to manufacturers, distributors, installers, contractors, regulatory officials, and owners. It is not intended to specify detailed methods of testing, installation, or servicing for the system or any of its components.4.2 This practice sets forth those methods and components necessary for minimum operation and safety. It also suggests methods for improved operation and effectiveness.1.1 This practice provides descriptions of solar domestic water heating systems and sets forth installation and service practices in new and existing one- and two-family dwellings to help ensure adequate operation and safety.2,31.2 This practice applies regardless of the fraction of heating requirement supplied by solar energy, the type of conventional fuel used in conjunction with solar, or the heat transfer fluid (or fluids) used as the energy transport medium. However, where more stringent requirements are recommended by the manufacturer, these manufacturer requirements shall prevail.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Sections 6 and 7.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Cooking can be one of the most polluting activities commonly and regularly occurring in residential environments. Capturing airborne cooking contaminants before they can mix with the indoor air is a critical indoor air quality control method.5.2 Range hoods are used in homes to remove cooking-generated contaminants above cooking surfaces before they mix with air in the rest of the house. This test method is used to measure the capture efficiency under specific conditions that permit comparisons and ratings of range hoods.5.3 Range hoods may be manufactured and intended to operate at different flow rates or using different inserts such as filters. This test method may be used to determine capture efficiency over the range of rated air flows and operating configurations of a range hood. The rated air flows shall be listed and shall be tested in accordance with HVI Test Procedure 916, IEC 61591, ASHRAE 51/AMCA 210, or equivalent. The maximum air flow allowed for this test method is 200 L/s.1.1 This test method measures the capture efficiency of wall-mounted domestic range hoods under controlled conditions in a test chamber.1.2 This test method applies to range hoods that exhaust air to outside and does not apply to recirculating range hoods.1.3 This test method only applies to range hood air flows up to 200 L/s and widths up to 0.91 m (36 in.).1.4 This test method is intended to quantify the capture efficiency of range hoods under controlled laboratory conditions suitable for rating.1.5 The values stated in SI units are to be regarded as standard. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
