1 Scope 1.1 This Standard applies to fans and ventilation equipment that is (a) cord-connected, rated at not more than 250 V; (b) permanently-connected to supply circuits of 600 V and less, single-phase or three-phase; (c) used in non-hazardous locations; (d) used in household, commercial, agricultural, or industrial locations; (e) used indoors or outdoors; and (f) used in accordance with the…

Scope 1.1 This Standard specifies the chassis and body requirements and safety equipment requirements for school buses. Note: The main purpose of this Standard is to provide the safest possible vehicle for students using school buses. It needs to be stressed, however, that standards are not substitutes for thorough, ongoing, and comprehensive safety training of students and drivers. 1.2 This…

1 Scope 1.1* This part of ISO 10524 specifies requirements for manifold pressure regulators (as defined in 3.6) intended to be connected to cylinders with nominal filling pressures up to 25 000 kPa at 15 °C and for line pressure regulators (as defined in 3.4) for inlet pressures up to 3 000 kPa and intended for use in pipeline systems for the following medical gases: - oxygen; - nitrous…

ISO/TS 17444-1:2012 defines metrics for the charging performance of electronic fee collection (EFC) systems in terms of the level of errors associated with charging computation. ISO/TS 17444-1:2012 is a toolbox standard of metrics. The detailed choice of metrics depends on the application and the respective context. ISO/TS 17444-1:2012 describes a set of metrics with appropriate definitions,…

ISO 9334:2012 de­fines terms relating to the optical transfer function and indicates, where pertinent, the mathematical relationships between those terms. It also defines important parameters that should be speci­fied in connection with optical transfer function testing. The terms and parameters de­fined in ISO 9334:2012 apply to all measurements of the optical transfer function for optical,…

This part of ISO 16145 specifies a method of protective coatings and its inspection of cargo oil tanks for crude oil tankers of not less than 5 000 tones deadweight, which are contracted for new building on or after 1 January 2013; or in the absence of a building contract, the keels of which are laid or which are at a similar stage of construction on or after 1 July 2013; or the delivery of which…

This part of ISO 18738 specifies requirements and methodology for the measurement and reporting of lift ride quality during lift motion. It does not specify acceptable or unacceptable ride quality. NOTE Lift performance parameters are often referenced in conjunction with lift ride quality. Parameters relevant to lift performance include jerk and acceleration. This part of ISO 18738 defines and…

This part of ISO 7148 specifies tribological tests of polymer-based plain bearing materials under specified working conditions, i.e. load, sliding velocity and temperature, with and without lubrication. From the test results, data are obtained which indicate the relative tribological behaviour of metal-polymer and polymer-polymer rubbing parts. The purpose of this part of ISO 7148 is to obtain,…

This International Standard specifies methods for evaluating the performance of engines designed for mopeds as defined in ISO 3833, in particular with a view to the presentation of power curves and specific fuel consumption at full load as a function of engine speed, for net power assessment. It is applicable to reciprocating internal combustion engines (spark-ignition), excluding free-piston…
