Wet pendulum slip resistance testing.

How the wet pendulum method is applied

The visit is a measurement of nominated pedestrian surfaces under wet test conditions. Premrest records the method, locations and results so the report matches the brief.

For multi-tenant or strata buildings, separate common-property surfaces from areas that need a tenant or owner’s permission. List foyers, lift approaches, shared stairs, external paths and wet-use facilities so the method and quote reflect the areas you need assessed. Discuss the testing scope with that list. Premrest provides this on-site testing in Sydney.

Nominate the person arranging keys, building access and any resident notices. Use the Sydney strata checklist to organise these details before booking.

Start with the purpose of the test.

Are you assessing a floor already in use, reviewing a recent treatment, or working to a project specification? Share the reason for testing and any previous findings. This helps Premrest confirm which surfaces and methods belong in the scope.

Wet pendulum testing

Wet pendulum testing assesses slip resistance under wet test conditions. It can help investigate selected pedestrian surfaces where water exposure is relevant. Tell us about the surface finish, normal use and any coatings or cleaning treatments.

Existing surfaces and new materials

AS 4663:2013 addresses measurement of existing pedestrian surfaces. AS 4586:2013 addresses classification of new pedestrian surface materials. The appropriate standard and test method depend on what is being assessed. A new-material classification should not automatically be treated as a current measurement of a floor already in service.

For builders pricing a tender or handing over a floor

If you are allowing for slip resistance testing in a Sydney tender, use the slip testing tender notes to decide what belongs in the price. If the floor is already installed and you need a pendulum test before practical completion or occupancy, see slip test before handover.

A report that fits the brief

Before booking, confirm the report requirements with Premrest. Useful context includes the locations assessed, the test method, recorded conditions and results. If your insurer, consultant or project team has requested particular information, include that request in your enquiry.

What the result can—and cannot—tell you

A result relates to the surfaces and conditions assessed. It does not guarantee a floor will never be slippery, or establish every aspect of a property’s compliance. Water, contamination, footwear, wear, cleaning and how people use the space also matter.

Before the visit

• List each surface and its location within the property.
• Describe usual wet or dry conditions and known concerns.
• Provide specifications, previous reports and treatment details where available.
• Confirm access, operating hours and who will meet the testing team.
