Joint draft standards

The objective of this document is to set out requirements and recommendations for the design, installation, operation and maintenance of electrical equipment in mines and quarries to ensure the safety of persons, livestock and property, and the proper functioning of plant.
Mining operations typically involve most aspects of electrical engineering, ranging from such areas as high voltage transmission to the control of undesirable static electricity. A substantial number of standards therefore apply to such work. This document consolidates updated requirements relating to these areas of application together into the one document.
This document is intended to be read in conjunction with AS/NZS 3000, AS 2067, AS/NZS 4024.1204, AS/NZS 4024.3901, AS 14990 (series), AS 20474 (series) and AS/NZS 7000.

The objective of this document is to provide a method for the quantification of the uncertainty of a time average of a set of air quality data obtained at a specified location over a defined averaging time period. The method is applicable to air quality data obtained by continuous or intermittent monitoring by means of a specified measuring system. The uncertainty of the time average depends on both the uncertainty of the measurement results and the uncertainty due to incomplete time coverage of the data set. This document is only applicable as follows:

a) The set of air quality data used to calculate the time average is representative of the temporal structure of the measured over the defined time period.
b) Appropriate information on the uncertainty of the measurement results is available.
c) The measurement results have all been obtained at the same location.

This document implements recommendations of the Guide to the expression of uncertainty in measurement (GUM).

This document is identical with, and has been reproduced from ISO 11222:2002, Air quality — Determination of the uncertainty of the time average of air quality measurements.

The objective of this document is to provide comprehensive guidance and specific statistical procedures for uncertainty estimation in air quality measurements including measurements of ambient air, stationary source emissions, indoor air, workplace atmospheres and meteorology. It applies the general recommendations of the Guide to the Expression of Uncertainty in Measurement (GUM) to boundary conditions met in air quality measurement. The boundary conditions considered include measurands varying rapidly in time, as well as the presence of bias in a series of observations obtained under conditions of intended use of methods of air quality measurement.

This document is identical with, and has been reproduced from ISO 20988:2007, Air quality — Guidelines for estimating measurement uncertainty.
