Lighting for roads and public spaces Part 2: Computer procedures for the calculation of light technical parameters for Category V and Category P lighting
Objective of this Standard is to specify the computer-based design procedures applicable to Categories V and P lighting for the calculation of light technical parameters (LTPs), as required, for the design or evaluation of road lighting in accordance with the requirements of AS/NZS 1158.1.1 and AS/NZS 1158.3.1. Note: The source code (SAA STAN) and shell program (STANSHELL) are available to purchasers of this Standard. Purchasers are not limited to the accompanying SAA STANSHELL software when applying this Standard. Alternative shell programs, using the SAA STAN source code, may be used to achieve conformance with the requirements of this Standard. The source code and shell program product is provided to purchasers of this Standard separate to this Standard download and in zipped format. Delivery methods of the product containing the source code and related program may change over time. The source code and shell program in the accompanying product are only permitted to be used, reproduced or modified by an authorized user in a way that meets the requirements of this Standard. They are not to be used for any other purposes.
