National Rail Safety Guidelines

National Rail Safety Guidelines
Updated 14 October 2008

A suite of national guidelines has been developed to assist rail safety regulators, industry stakeholders and other relevant parties with duties under the rail safety legislation to understand and comply with the national model Rail Safety Bill 2006 and model Regulations.

National guidelines are administrative documents intended to provide practical advice to rail safety regulators and rail transport operators or other parties to whom legislative duties apply. Depending on the subject matter, the guidelines in this suite may:
articulate how rail safety regulators will behave when undertaking their functions to ensure that their processes are transparent to the duty holders (e.g. national compliance and enforcement);
provide nationally consistent and/or integrated processes by which rail safety regulators will make decisions (e.g. Business Rules for Uniform Administration);
assist duty holders with the interpretation of legislative provisions and provide practical guidance for satisfying these requirements (e.g. Accreditation, Safety Management Systems, Managing Risks SFAIRP, Fatigue Management).
The suite of national guidelines has been developed through the NTC processes by the NTC and rail safety regulators acting as lead agents to the NTC. The Rail Safety Regulators Panel, Australasian Railway Association and Rail Tram and Bus Union have had input into the drafting process.

Specification of Reinforcing Steel Bar

Because there are projections on surface along with axis and nodes of fixed-distance on horizontal direction, it has excellent adhesion on concrete and it is widely used as materials for civil work or architecture construction. According to its strength, it is classified by common reinforcing bar (SD300), high tension reinforcing bar (SD350, SD400), and ultra high tension reinforcing bar (SD500)
