Daniels Associates provide on-site slip testing services for wet and dry floors. These tests being the WET Pendulum and DRY floor friction test. Below is a brief explanation of the different test methods specified under the two different standards for testing new surfaces and existing surfaces.

Existing Surfaces: There are two slip testing methods specified in the Australian Standard ASNZS 4663 Slip resistance measurement of existing pedestrian surfaces. These tests being

  • Wet pendulum slip test

  • Dry floor friction slip test

Quote from the Standard’s (ASNZS 4663) Preface

A new floor is considered to become an existing floor once it has been installed and made available for pedestrian traffic, other than movements specifically for purposes of formal testing to determine compliance with AS/NZS 4586. New floors are to be tested in accordance with AS/NZS 4586.

The objective of this Standard is to provide users, maintenance organizations and facility managers with standardized methods of testing existing in situ pedestrian surface materials for determination of their slip resistance.

Wet testing is carried out using two types of rubber materials, 55 rubber slider , which has been traditionally used for testing outdoor surfaces and the 96 rubber slider  which was specifically developed to replace the TRL rubber for testing smoother indoor surfaces, as it provides more discrimination between such internal surfaces.

HB 197, An introductory guide to the selection of slip resistant pedestrian surfaces, establishes a basis for specifying pedestrian surface materials for various locations based on wet slip resistance classifications that are obtained when testing to AS/NZS 4586, Slip resistance classification of new pedestrian surface materials. HB 198 recognizes that slip resistance test methods have inherent limitations.

New Surfaces: There are four slip testing methods specified in the Australian Standard ASNZS 4586. Slip resistance classification of pedestrian surface materials comprise. These tests being

  • Wet pendulum slip test

  • Dry floor friction slip test

  • Wet barefoot slip test

  • Oil wet ramp slip test

Quote from the Standard’s (ASNZS 4586) Preface

The objective of this Standard is to provide users and specifiers of pedestrian surface materials (architects, engineers, ergonomists, facility managers, manufacturers and the like) with means for classifying such surfaces according to their pedestrian slip resistance for use in the selection of surfaces.

The slip resistance classifications have been determined for unused surfaces using specific conditions, for instance special rubbers, barefoot testing, and so on. These classifications are based on an assessment of the contribution of a pedestrian surface to the risk of slipping and they will assist in the specification of a surface material suitable for most pedestrian applications. Factors such as usage, cleaning systems, applied coatings and patterns of wear may affect the characteristics of the surface after classification.
