Fan Standards

5.1 The fan pressurization procedure provides a relatively fast evaluation of the airtightness of building envelopes. In order for the accuracy of the test results to be known, the airflow rate measurement technique of the fan pressurization system must be calibrated. 5.2 This test...

5.1 Fan Energy-This standard practice determines the fan energy requirements for a constant speed and demand controlled kitchen ventilation system and estimates the savings. It can be used to compare systems' fan savings potential. 5.2 Heating and Cooling Energy-This standard...

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 Effects of Air Change-Air change often accounts for a significant portion of the heating or air-conditioning load of a building. It also affects the moisture and contaminant balances in the building. Moisture-laden air passing through the building envelope can permit condensation and cause...

The purpose of this document is to establish air-conditioning design guidelines that will apply to most systems rather than the specific design of any particular system. Operating conditions and characteristics of the equipment will determine the design of any successful system; since these...

019170-000000-000000 1 Scope 1.1 These requirements cover solid state speed controls rated 300 volts or less, single phase, intended to be connected to 15 - 20 ampere branch circuits and intended to be installed in accordance with the National Electrical Code, ANSI/NFPA 70 and used with: a)...

1.1 This practice provides guidelines for acoustic emission (AE) examinations of fiberglass reinforced plastic (FRP) fan blades of the type used in industrial cooling towers and heat exchangers. 1.2 This practice uses simulated service loading to determine structural integrity. 1.3 This...

The techniques outlined in this SAE Recommended Practice were developed as part of an overall program for determining and evaluating fuel consumption of heavy-duty trucks and buses, but it is applicable to off highway vehicles as well. It is recommended that the specific operating conditions be...

Three levels of fan structural analysis are included in this practice: a Initial structural integrity. b In-vehicle testing. c Durability (laboratory) test methods. The initial structural integrity section describes analytical and test methods used to predict potential resonance and,...

603350-000020-000400 1 Scope This clause of Part 1 is replaced by the following. This part of IEC 60335 deals with the safety of electric heat pumps , including sanitary hot water heat pumps , air conditioners , and dehumidifiers incorporating motor-compressors and hydronic fan coils units ,...

4.1 Hydraulic cleaning methods include equipment that uses water and water velocity to clean the invert and walls of Thermoplastic Sewer Pipe. 4.2 The practice of high-velocity sewer cleaning is best described as a hydraulic cleaning method that uses water pressure to remove obstructions and...

The purpose of this document is to provide guidance on in-flight thrust determination of engines that are impacted by intentional or unintentional thrust vectoring. However, as indicated in the Foreword, the field of aircraft thrust vectoring is varied and complex. For simplicity and coherence of...

600790-000130-000000 1 Scope Modification of the Clause 1 to replace with the following: 1.1 This part of IEC 60079 standard gives requirements for the design, construction, assessment, verification and marking of rooms used to protect internal equipment: - a located in a Zone 1 or Zone 2 or Zone...

1.1 This practice covers uniform procedures for determining and reporting the dosage rate of oil spill dispersant application equipment. 1.2 This practice is applicable to spray systems employing booms and nozzles and is not fully applicable to other systems such as fire monitors, sonic...

1.1 This guide covers design criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems. This guide is not intended to be restrictive to a specific configuration. 1.2 This guide covers spray systems employing booms and nozzles and is not...

This specification covers the minimum requirements for construction of fiber-reinforced thermoset plastic fans (both centrifugal and axial) and blowers, and provides for a common basis for determining safe operating speeds. The fan housing shall be of laminate construction consisting...

This Aerospace Information Report (AIR) addresses the subject of aircraft inlet-swirl distortion. A structured methodology for characterizing steady-state swirl distortion in terms of swirl descriptors and for correlating the swirl descriptors with loss in stability pressure ratio is presented. The...

4.1 Hydraulic cleaning methods include equipment that uses water and water velocity to clean the invert and walls of the vitrified clay sewer pipe. 4.2 The practice of high-velocity sewer cleaning is best described as a hydraulic cleaning method that uses water pressure to remove obstructions and...

1.1 This test method covers procedures for determining air performance characteristics of series universal motor/fan systems used in commercial and household upright, canister, stick, hand-held utility, combination-type vacuum cleaners, and household central vacuum cleaning systems. 1.2...
