Liquid flow measurement in open channels — Velocity-area methods — Collection and processing of data...
For determining the discharge in open channels by the velocity-area method, components of the flow need to be measured. The total uncertainty in discharge is a combination of the uncertainties in these components. This ISO-Standard specifies a standard basis for collecting and processing the data required to compute the component uncertainties for determining the total uncertainty in discharge.

1.1 Scope
1.1.1 This Standard applies to gas-fired brooders, (other than hot water, or steam), for use with natural gas and/or propane. Brooders outside the scope of this Standard may be examined to the intent of applicable codes and standards and a report issued to the Authorities having jurisdiction for acceptance.
1.1.2 This Standard applies to gas-…

Industrial-process control valves. Part 6: Mounting details for attachment of positioners to control...
Permits a variety of positioning devices which respond to a linear motion to be mounted on the actuator of a control valve, either directly or by employing an intermediate mounting bracket.
The standardized mounting applies to positioners which are mounted on the side of the actuator, to those actuators which have a travel of 100 mm or less, and is designed to cover three basic types of actuator…
Guide to voltage fluctuation limits for household appliances (relating to IEC Publication 60555-3)
IEC 60555-3 specifies limits for the voltage fluctuations that may be produced by an individual appliance and gives methods of test and calculation. The purpose of this report is to explain the way in which the limits and test methods were developed so as to help understanding of the standard and the way in which it should be used. After reviewing the need for voltage fluctuation limits, the…
