Introduction

AS 1562.1 2023 is a standard developed by the Australian Standards Committee to provide guidelines for the design and installation of stairs in buildings. This standard is part of the AS 1562 series which covers various aspects of stairs, including materials, design, construction, and maintenance.

In this document, we will provide an overview of AS 1562.1 2023 and discuss its key requirements and specifications.

Scope

AS 1562.1 2023 covers the design and installation of interior and exterior stairs in residential, public, and

commercial buildings. These stairs may be constructed using different materials such as timber, concrete, steel, or glass. The standard provides guidance on various elements of stairs, including treads, risers, handrails, balustrades, and landings.

Key Requirements Treads and Risers

AS 1562.1 2023 specifies minimum requirements for the dimensions of treads and risers. The standard states that the minimum tread depth should be 250mm, and the maximum riser height should be 190mm. These dimensions are intended to ensure safe and comfortable use of the stairs.

Handrails

The standard requires handrails to be installed on at least one side of the stairs. The height of the handrail should be between 900mm and 1100mm measured vertically from the pitch line. Handrails should be continuous along the full length of the stairs, including landings and ramps.

Balustrades

AS 1562.1 2023 provides guidelines for the design and installation of balustrades. Balustrades are required to be

installed on stairs with a fall height greater than 1000mm. The standard specifies the minimum height of balustrades, which should be at least 900mm above the pitch line. The design of the balustrades should prevent the passage of a 125mm sphere.

Landings

The standard defines the minimum dimensions for landings at the top and bottom of the stairs, as well as intermediate landings. The landing should have a minimum length equal to the width of the stairway and a minimum width of 750mm. Landings should be level and have a slip-resistant surface.

Lighting

AS 1562.1 2023 also addresses the lighting requirements for stairs. Lighting should be provided to ensure safe use of the stairs, especially in areas with low natural light. The standard specifies the minimum illuminance levels for stairways and landings.
