Asbra Safety Stair Treads & Nosing Independent Slip Resistant Testing Information

Latham Australia Pty Ltd has had independent testing carried out by a NATA accredited laboratory in Accordance with AS 4586-2013 Slip resistance classification of new pedestrian surface materials – Appendix A & D. Stair tread compliance is demonstrated by achieving the values in either Wet Pendulum Test (appendix A) or the Oil-wet Inclining Ramp Test (appendix D). 

APPENDIX A

Classification of Pedestrian Surface Materials According to the AS 4586 Wet

Notes:

1. While slider 96 or slider 55 rubbers may be used, the test report shall specify the rubber that was used.
2. It is expected that these surfaces will have greater slip resistance when dry.
3. SDV may be calculated by using the tables that are given in Appendix F, and the minimum SRV that is considered appropriate for a level surface (see examples given in Appendix F).

(Adapted from AS 4586-2013 Table 2)

To comply with the National Construction Code (NCC) Slip Resistance Requirements, the test results of the ‘Wet Pendulum Test’ must achieve the values P3 or above for the surface when dry and P4 or above for the surface when wet. More information on the NCC available in SA HB 198:2014.

The established results are detailed as follows:

Latham Suregrip Silicon Carbide Mineral Insert Treads and Nosings

• Slip Resistance Value (SRV) - Slider 55: 75
• Classification according to Appendix A: P5

Latham Supagrit Silicon Carbide Mineral Insert Treads and Nosings

• Slip Resistance Value (SRV) - Slider 55: 57

• Classification according to Appendix A: P5

Latham Rufazel Slip Resistant Tread and Plate

• Slip Resistance Value (SRV) - Slider 55: 64

• Classification according to Appendix A: P5

APPENDIX D

Classification of Pedestrian Surface Materials According to the Oil-Wet Inclining Platform Test

(Adapted from AS 458-2013 Table 5)

To comply with the National Construction Code Slip Resistance Requirements, the test results of the ‘Oil-Wet Inclining Platform Test’ must achieve the values R10 or above for stair tread nosings when dry and R11 or above for stair tread nosings when wet.

The established results are detailed as follows:

Latham Suregrip Silicon Carbide Mineral Insert Treads and Nosings

• Corrected Mean Overall Acceptance Angle: 340

• Classification according to Appendix D: R12

Latham Supagrit Silicon Carbide Mineral Insert Treads and Nosings

• Corrected Mean Overall Acceptance Angle: 290

• Classification according to Appendix D: R12

Latham Supagrit Silicon Carbide Mineral Insert Treads and Nosings

• Corrected Mean Overall Acceptance Angle: 330

• Classification according to Appendix D: R12

ACCELERATED WEAR TEST (AWT)

Although this test does not currently form part of the Australian Standard, the Accelerated Wear Test is increasing in popularity as a method for accessing individual products durability over time. A small pad is rubbed across a test area with 1kg of pressure applied this is normally done 500 or 1000 times and the product measured to see what the wear is. Latham are confident there would be no wear on our products listed here, however the test apparatuses pad has worn out after 30-40 passesover the slip resistant inserts in our products and a result cannot be achieved, it would seem this test is for far less aggressive substrates than stair tread inserts.

INTERNATIONAL STANDARDS

Many of Latham Asbraloy and Absrabronz Safety Stair Tread Nosings and Inserts also comply with International Standards and standards of best practice. It should be noted that the Australian Standards and National Construction Code in relation to Slip Resistance and Pedestrian Access, Access to Premises and Buildings, and Design Access and Mobility are some of the most up to date in the world and are highly respected and enforced by councils and certifiers. Selected Latham profiles meet or exceed the requirements of the A.D.A (USA), The State of California Code for Stair for the visually impaired, ANSI B101.1, ANSI A1264.2, ASTM F1637, UL-410, the slip resistant requirements of the National Floor Safety Institute, ISSA (CMI), DIN51130, DIN51097, EN13845.
