1.1 This Standard provides a procedure to predict the sound level received at a distance from an industrial plant that is due to sound from the plant.

Notes:
(1) It is envisaged that this method will be used to predict sound levels (Leq, Lmax, etc) from the industrial plant being considered at the property line or at nearby residences.
(2) This procedure only predicts sound levels produced by the sources being considered. Background sound levels due to traffic, other plants, etc, not taken into account by the prediction may already exist at particular receivers.

1.2 To use this Standard, noise source information shall be available as sound power or sound pressure levels in octave or one-third octave bands.

Note: This prediction may be taken as representative of the upper limit of sound levels. Ground effect, which can reduce sound levels by up to 20 dB, is not part of the prediction. Weather conditions (principally temperature inversions and following winds) that considerably reduce ground effect are common in temperate climates. If measurements are made to confirm these upper-limit predicted values, they should be taken downwind from the source or during a temperature inversion. If ground effect is to be considered, a simple approach is to use the difference in propagation between hard and soft ground given in Table 3.5 of the CMHC Publication Road and Rail Noise: Effects on Housing.

2.1.1 This standard specifies the administrative requirements of the telecommunications infrastructure within a new, an existing, or a renovated (primarily commercial) building or campus. Areas of the infrastructure to be administered are shown in figure 2.1-1 and include:

(a) terminations for the telecommunications media located in work areas, telecommunications closets, equipment rooms, and entrance facilities.
(b) telecommunications media between terminations;
(c) pathways between terminations that contain the media;
(d) spaces where terminations are located;
(e) bonding/grounding, as it applies to telecommunications.

Figure 2.1-1 complies with the infrastructure standards listed in clause 1.4 and illustrates the scope of this standard.

2.1.2 This standard also specifies requirements for the collection, organization, and presentation of as-built data.

2.1.3 In addition to providing requirements and guidelines for a traditional paper-based administration system, this standard also serves as a platform for the design of computer-based administration tools, which may be necessary as the information base gets larger.

2.1.4 This standard does not cover the administration of either end-user equipment attached to the telecommunications outlet connector or application-specific devices in the telecommunications spaces, e.g., data/voice switching equipment and computers. However, this standard may be usable as a platform for specifying an administration scheme for end-user and application-specific equipment.

2.1.5 This standard does not specify requirements for user safety.

Scope

This Handbook provides guidance on how information about aircraft noise and its impacts on areas in the vicinity of airports can be presented in a clearer, less technical and more informative manner for the general public. It is not a standard and does not propose any absolute value for when aircraft noise is acceptable or unacceptable. Information provided in accordance with This Handbook may assist individuals in making their own judgements about the acceptability of aircraft noise, taking into account their own personal circumstances. This Handbook is also not intended as a guide to land use planning and building treatments in the vicinity of an airport. That is a matter for Australian Standard AS 2021:2015, Acoustics – Aircraft noise intrusion – Building siting and construction
(see Clause 1.3).
The tools presented in this Handbook seek to assist in explaining aircraft noise as it is perceived on the ground in an open air environment.

Scope

This Standard sets out a method for cable selection for those types of electrical cables and methods of installation that are in common use at working voltages up to and including 0.6/1 kV at 50 Hz a.c.
NOTE: Although the Standard specifically applies to a.c. installations, it may also be applied to d.c. installations.
Four criteria are given for cable selection, as follows:
(a) Current carrying capacity.
(b) Voltage drop.
(c) Short-circuit temperature rise.
(d) Economic optimization.
This Standard provides sustained current-carrying capacities and voltage drop values for those types of electrical cable and installation practices in common use in Australia. A significant amount of explanatory material is also provided on the application of rating factors that arise from the particular installation conditions of a single circuit or groups of circuits. Also, provided in Section 5 is information on cable selection based on short-circuit temperature limits.
NOTE: A number of worked examples on cable selection are included in Appendix A.
This Standard does not take into account the effects that may occur owing to temperature rise at the terminals of equipment and reference is necessary to AS/NZS 3000 and the individual equipment Standards.
NOTE: For ease of reference, an index of the Tables included in this Standard is provided in Appendix B.

Comprises two parts:

– Part 1 provides provisions that constitute the minimum regulatory requirements for a safe electrical installation.

– Part 2 provides work methods and installation practices that are ‘deemed to comply’ with the requirements of Part 1 and are intended to achieve certainty of compliance with the requirements of Part 1.

Guidance is provided in appendices.

Scope

This Standard sets out requirements for the design, construction and verification of electrical installations, including the selection and installation of electrical equipment forming part of such electrical installations.
These requirements are intended to protect persons, livestock, and property from electric shock, fire and physical injury hazards that may
arise from an electrical installation that is used with reasonable care and with due regard to the intended purpose of the electrical installation.
In addition, guidance is provided so that the electrical installation will function correctly for the purpose intended and takes into account
mitigating the foreseeable adverse effects of disruption to supply.
