Australian Standards for Slip Testing

Understanding AS 4586:2013, AS 4663:2013, and HB 198:2014 — the standards that govern floor slip resistance testing in Australia.

Understanding the Australian Standards Framework

Floor slip resistance in Australia is governed by a framework of standards that define how surfaces should be tested, classified, and assessed for safety. These standards provide the scientific basis for determining whether a floor is safe for pedestrian use and are referenced in building regulations, workplace health and safety legislation, and industry codes of practice.

The three key documents in this framework are:

AS 4586:2013

Slip resistance classification of new pedestrian surface materials

AS 4663:2013

Slip resistance measurement of existing pedestrian surfaces

HB 198:2014

Guide to the specification and testing of slip resistance of pedestrian surfaces

Together, these documents provide a complete system for testing, classifying, and selecting appropriate floor surfaces. Surface Test Australia tests floors in accordance with these standards, providing you with documented results and P-rating classifications that demonstrate compliance.

AS 4586:2013 — Classification of New Surface Materials

AS 4586:2013 is the Australian Standard for slip resistance classification of new pedestrian surface materials. It specifies the test methods and classification systems used to assess the slip resistance of flooring products before they are installed.

This standard is primarily used by flooring manufacturers, architects, builders, and specifiers to classify and select appropriate flooring products. When a tile manufacturer provides a P-rating for their product, that classification has been determined using the methods specified in AS 4586.

What AS 4586 Covers

  • Wet pendulum test method — The primary test using a calibrated pendulum device to measure friction on a wet surface, producing a British Pendulum Number (BPN) classified into P-ratings (P0 to P5)
  • Oil-wet ramp test method — A secondary test measuring slip resistance on an inclined surface with oil contamination, producing R-ratings (R9 to R13)
  • Wet/barefoot ramp test method — Tests for areas where people walk barefoot, such as pool surrounds and bathrooms, producing A, B, or C classifications
  • Equipment specifications — Detailed requirements for testing equipment, rubber sliders, calibration standards, and surface preparation procedures

Who Uses AS 4586?

Flooring manufacturers use AS 4586 to classify their products. Architects and specifiers use the P-rating data to select appropriate flooring for different environments. Builders and developers reference these classifications to ensure new installations meet the required slip resistance levels specified in the Building Code of Australia and HB 198.

AS 4663:2013 — Measurement of Existing Surfaces

AS 4663:2013 is the Australian Standard for slip resistance measurement of existing pedestrian surfaces. While AS 4586 deals with new products in laboratory conditions, AS 4663 addresses the real-world challenge of testing floors that are already installed and in use.

This is the standard that applies to the vast majority of slip testing performed by Surface Test Australia. When Greg tests your floors on-site, he is working in accordance with AS 4663.

What AS 4663 Covers

  • On-site wet pendulum testing — Methodology for using the wet pendulum tester on installed floor surfaces, accounting for real-world conditions
  • Surface preparation procedures — How existing surfaces should be prepared for testing, including cleaning protocols
  • Recording environmental conditions — Requirements for documenting temperature, humidity, and surface conditions at the time of testing
  • Reporting requirements — What information must be included in a slip test report for the results to be valid and defensible

Why AS 4663 Matters for Property Owners

A floor that was adequately slip-resistant when installed may not stay that way. Foot traffic, cleaning chemicals, wear, environmental exposure, and surface treatments all change a floor's slip resistance over time. AS 4663 provides the methodology for assessing the current state of your floors — not what they were when new, but what they are right now.

Testing to AS 4663 gives you documented, defensible evidence of your floor's slip resistance at a specific point in time. This documentation is essential for demonstrating due diligence under workplace health and safety legislation and is commonly required by insurers, WorkSafe investigators, and legal proceedings.

P-Rating Classification System

The P-rating scale classifies wet slip resistance from P0 (very slippery) to P5 (excellent). It is the primary classification used in Australia for general pedestrian areas.

P-Rating BPN Range Classification
P0 0 – 11 Very slippery when wet
P1 12 – 19 Slippery when wet
P2 20 – 27 Moderate slip resistance
P3 28 – 34 Acceptable slip resistance
P4 35 – 44 Good slip resistance
P5 45+ Excellent slip resistance

R-Rating Classification System

R-ratings are determined using the oil-wet ramp test and are primarily used for industrial and commercial environments where oil or grease contamination is expected. While less commonly referenced than P-ratings for general pedestrian areas, they remain relevant for specific applications.

R-Rating Inclination Angle Typical Application
R9 6° – 10° General indoor areas with low contamination risk
R10 10° – 19° Kitchens, cafeterias, workshops with moderate contamination
R11 19° – 27° Food processing areas, commercial laundries
R12 27° – 35° Industrial kitchens, meat processing, dairy
R13 35°+ Heavy industrial with significant oil/fat contamination

HB 198:2014 — The Practical Guidance Handbook

HB 198:2014, Guide to the specification and testing of slip resistance of pedestrian surfaces, is the essential companion document to AS 4586 and AS 4663. While the standards define how to test, HB 198 provides practical guidance on what slip resistance levels are appropriate for different environments.

HB 198 includes detailed tables showing recommended minimum P-ratings for a wide range of building types and specific areas within those buildings. It is the primary reference used by architects, builders, and facility managers when selecting or assessing floor surfaces.

Recommended Minimum P-Ratings by Environment

The following table provides general guidance based on HB 198 recommendations. Actual requirements may vary depending on specific circumstances, slope, expected contamination, and the vulnerability of users.

Environment Min. P-Rating Notes
General indoor — dry areas P3 Offices, corridors, retail, lobbies
Building entrances P4 Where water is tracked in from outside
Bathrooms & amenities P4 Public, commercial, and aged care wet areas
Commercial kitchens P4/P5 Higher ratings for areas with grease/oil contamination
Aged care facilities P4 All common areas; higher for wet areas
Swimming pool surrounds P5 Barefoot areas constantly exposed to water
Ramps (accessible) P4 Higher P-rating required for steeper gradients
Outdoor walkways P4 Exposed to rain and environmental contamination
Hospital corridors P3 Higher in wet areas, bathrooms, and entrances
Car parks (pedestrian areas) P4 Ramps and pedestrian walkways within car parks

Important Disclaimer

This table provides general guidance only. The specific P-rating required for your premises depends on multiple factors including the type of environment, expected contamination, floor slope, and the vulnerability of people using the space.

Who Needs to Comply?

In Victoria, multiple stakeholders share responsibility for ensuring floor surfaces are safe for pedestrians.

Property Owners & Managers

Under the Occupational Health and Safety Act 2004 (Vic), persons who manage or control a workplace have a duty to ensure, so far as is reasonably practicable, that the workplace and its facilities are safe. This includes maintaining floor surfaces at adequate slip resistance levels. Regular slip testing demonstrates due diligence.

Facility Managers

Facility managers are often the people responsible for implementing floor safety programs on a day-to-day basis. This includes scheduling regular slip testing, maintaining records, acting on test results, and ensuring appropriate cleaning and maintenance regimes are in place.

Builders & Developers

The Building Code of Australia (BCA) requires that floor surfaces in new buildings meet appropriate slip resistance classifications. Builders and developers must ensure that specified flooring products are installed correctly and meet the required P-ratings before handover. Post-installation testing verifies compliance.

Body Corporates & Strata Managers

Body corporates and strata managers are responsible for common areas within multi-unit developments. This includes lobbies, corridors, stairwells, car park walkways, and outdoor common areas. Regular slip testing of these shared spaces is an important part of meeting collective obligations.

Aged Care Operators

Aged care facilities face heightened requirements due to the vulnerability of their residents. The Aged Care Quality Standards and state regulations require operators to manage environmental risks, including floor safety. Documented slip testing is essential for demonstrating compliance.

Hospitality & Retail Operators

Restaurants, cafes, bars, hotels, and retail stores all have high pedestrian traffic and unique slip risks from food, drinks, and cleaning operations. Operators have a duty of care to both staff and customers. Regular testing helps manage risk and provides evidence of compliance efforts.

Australian Standards — Frequently Asked Questions

Common questions about AS 4586, AS 4663, P-ratings, and compliance requirements.

What is the difference between AS 4586 and AS 4663?
AS 4586:2013 covers the classification of new pedestrian surface materials — it is used to assess and rate new flooring products before they are installed. AS 4663:2013 covers the measurement of existing pedestrian surfaces — it is used to test floors that are already in place and in use. Both standards use the wet pendulum test method and the P-rating classification system, but they serve different purposes in the lifecycle of a floor surface.
What is HB 198:2014?
HB 198:2014 is the Guide to the specification and testing of slip resistance of pedestrian surfaces. It is a companion handbook to AS 4586 and AS 4663 that provides practical guidance on selecting appropriate slip resistance levels for different environments. It includes tables showing recommended minimum P-ratings for various building types and areas, making it an essential reference for architects, builders, and facility managers.
Are P-ratings legally required in Victoria?
While P-ratings themselves are not directly mandated by legislation, the Occupational Health and Safety Act 2004 (Vic) and the Building Code of Australia (BCA) require that floor surfaces be safe for pedestrians. The Australian Standards and HB 198 are referenced in these regulations as the accepted method for demonstrating floor safety compliance. In practice, meeting the recommended P-ratings from HB 198 is considered the benchmark for demonstrating due diligence.
What is an R-rating and how does it differ from a P-rating?
R-ratings (R9 to R13) are determined using the oil-wet ramp test, which measures slip resistance on an inclined surface with oil contamination. They are primarily used in industrial settings where oil or grease contamination is common. P-ratings (P0 to P5) are determined using the wet pendulum test with water and are the primary classification used for general pedestrian areas in Australia. Most commercial and public spaces reference P-ratings rather than R-ratings.
What Australian Standards apply to slip testing?
The two key standards are AS 4586:2013 (Slip resistance classification of new pedestrian surface materials) and AS 4663:2013 (Slip resistance measurement of existing pedestrian surfaces). AS 4586 applies to new flooring installations, while AS 4663 covers testing of floors already in use. Both standards use the wet pendulum test method.
What is AS 4586?
AS 4586:2013 is the Australian Standard for slip resistance classification of new pedestrian surface materials. It specifies the test methods and classification system (P-ratings for wet pendulum, R-ratings for oil-wet ramp) used to assess how slip-resistant a new floor surface is before installation.
What is AS 4663?
AS 4663:2013 is the Australian Standard for slip resistance measurement of existing pedestrian surfaces. It provides the methodology for testing floors that are already installed and in use, helping property owners and facility managers verify that their floors maintain adequate slip resistance over time.
