Abstract On a multi-access network, one of the PIM-SM (PIM Sparse Mode) routers is elected as a Designated Router. One of the responsibilities of the Designated Router is to track local multicast listeners and forward data to these listeners if the group is operating in PIM-SM. This document...
1.1 This test method can be used to measure and validate successful design, installation and commissioning of commercial kitchen HVAC and makeup air systems for specific installations. 1.2 This test method field evaluates commercial kitchen ventilation system airflows and pressures. 1.3 This...
The information and drawings in this manual are presented primarily to illustrate the elements of construction and installation of commercial kitchen ventilation systems. The information is intended to encourage more standardization in installations and to call attention to the appropriate...
1.1 This test method can be used to measure and validate successful design, installation and commissioning of commercial kitchen HVAC and makeup air systems for specific installations. 1.2 This test method field evaluates commercial kitchen ventilation system airflows and pressures. 1.3 This...
This European Standard specifies a set of assumptions, requirements and validation tests for procedures used for the calculation of the annual energy needs for space heating and cooling of a room in a building where the calculations are done with a time step of one hour or less. This European...
Characteristics of vertical hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing.
Characteristics of vertical hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing.
This European Standard sets out the level of input and output data, and prescribes the boundary conditions required for a calculation method of the sensible cooling load of a single room under constant and/or floating temperature taking into account the limit of the peak cooling load of the system....
This standard specifies functional requirements and specific safety requirements for free-standing balancing beams.
This Data Item presents four procedures for the design of counterweights which, when fixed to shafts rotating with constant angular velocity, improve the balance of machines that incorporate single degree-of-freedom, planar, multibar linkage mechanisms. The frame shaking force† and/or the...
Applies to rotors balanced in balancing machines, in their own housing and in situ.
Characteristics of horizontal hard-bearing balancing machines are described which make such machines suitable for gas turbine rotor balancing.
This International Standard specifies a single convention for balancing the individual components (shafts or rotors, and fitments) of a keyed assembly. It is intended to provide compatibility of all balanced components so that when they are assembled they will meet the overall balance...
This International Standard gives specifications for vibration and balance limits of fans for all applications except those designed solely for air circulation, for example, ceiling fans and table fans. However, it is limited to fans of all types installed with a power of less than...
The use of trend data from Building Energy Management Systems (BEMS) is a cost-effective solution to provide the necessary data for ongoing commissioning. This paper presents the use of three different virtual air flow meters, along with trend data, recorded every 15 minutes for the...
This document specifies those requirements and procedures for periodic tests to insure maintenance of balance machine capabilities for balancing jet engine components. It will specify: (a) Requirements for tests (b) Calibration tests (c) Residual unbalance and accurate angle and...
This ARP specifies both the nominal dimensions and the tolerances for a series of ball bearings with semifinished inside diameters which are suitable for supporting gas turbine rotating components in dynamic balancing machines.
Characteristics of vertical non-rotating balancing machines are described which make such machines suitable for balancing rigid unbladed gas turbine rotors or rotors with fixed, integral blades.
ISO 21940-11:2016 establishes procedures and unbalance tolerances for balancing rotors with rigid behaviour. It specifies a) the magnitude of the permissible residual unbalance, b) the necessary number of correction planes, c) the allocation of the permissible residual unbalance to the...
