Anti-slip Test / Pendulum Testing

Enhancing Safety with SWISSGriP®

At SWISSGriP® Middle East, we offer industry-leading testing standards to ensure safety, quality, and transparency. One of the most accurate and widely accepted methods in the world today is the SRT Pendulum Test, and SWISSGriP® brings this trusted standard to the Middle East! We validate anti-slip performance for a wide range of surfaces.

The Pendulum Test (SRT: Skid Resistance Test) is an internationally recognized method for measuring slip resistance. Originally accepted in countries like the UK, USA, and Australia, this method is now available across the Middle East through SWISSGriP®. It determines the coefficient of slip resistance on concrete, tiled, or treated surfaces with reproducible and reliable results — ideal for barefoot and footwear traffic areas.

Many testing methods are in use worldwide, but they often lack consistency. The Pendulum Test stands out for being accurate, calibrated, and easy-to-use on-site. It enables on-site evaluation—even after months or years of use—helping assess whether a surface still meets anti-slip safety standards.

From swimming pools and spas to hospitals and office buildings; architects and facility managers now have access to a clear, quantifiable method to evaluate surface safety. Even when tiles or floors are rated with high slip resistance classes, real-world conditions may not reflect those ratings. The SRT Pendulum test offers these insights for accident prevention, facility certification, surface risk re-evaluation, and resolving safety complaints.

“Across 50+ countries, the ramp test is common but lacks global standardization. The Pendulum Test, on the other hand, delivers reproducible and verifiable data—making it the standard for objective anti-slip testing. SWISSGriP® has invested in this system to offer measurable safety across our markets.”

Slip-Resistance Testing: Pendulum Test

The Pendulum Test under the BS 7976 standard is a reliable method for measuring slip potential in both wet and dry conditions. It can be performed both in the lab and on-site. It is ideal for post-installation verification around surfaces that may become wet like bathrooms, pool areas, healthcare facilities, and commercial spaces.

While the Pendulum Test (BS 7976) is recommended for most settings, a ramp test method (which provides an R-rating) is typically used in controlled laboratory environments. This is more relevant for oily surfaces like commercial kitchens and industrial workshops. However, ramp tests cannot be performed once the flooring is installed. It is suitable for both new and existing floors and is regarded as the most reliable and practical test.

Two different sliders are used during the pendulum test:

• Slider 96 : Mimics a standard shoe sole, suitable for general pedestrian areas.
• Slider 55 : Mimics human skin, suitable for barefoot areas like bathrooms and swimming pools.

To conduct a valid test, five measurements are taken and averaged to determine the Slip Resistance Value (SRV). Based on the SRV, the surface is assigned a slip resistance class.

Wet Pendulum Test Classification ↓

Wet Pendulum Class SRV Slider 55 SRV Slider 96 Risk of Slips
P0 < 12
P1 < 20 12 → 24 Very High
P2 20 → 34 25 → 34 High
P3 35 → 39 35 → 44 Moderate
P4 40 → 44 45 → 54 Low
P5 > 44 > 54 Very Low

While P5 represents the highest level of slip resistance, it may not always be appropriate for every setting. For example, surfaces that are too rough might not be suitable for barefoot zones like pools or bathrooms. It’s important to balance safety with comfort and functionality.

Wet Barefoot Inclining Platform Test ↓

Wet Inclining Platform Test Angle Slipping Risk
A ≥ 12° High
B ≥ 18° Medium
C ≥ 24° Low

This method uses a safety-harnessed person walking on an inclined platform sprayed with water. The slip resistance is based on the angle at which slipping is predicted.

Oil Wet Inclining Platform Test ↓

Oil Inclining Platform Test Angle
R9 ≥ 6° & ≤ 10°
R10 ≥ 10° & ≤ 19°
R11 ≥ 19° & ≤ 27°
R12 ≥ 27° & ≤ 35°
R13 ≥ 35°

Commonly used for industrial environments and commercial kitchens, this test evaluates slip-resistance with oil as the contaminant. Safety boots are worn during testing. These R-ratings are often printed by tile manufacturers, though they may not reflect real-world conditions unless independently verified post-installation.

Accelerated Wear Test (here we have to add the image provided by the client)

Anti-slip performance should be sustainable over time. That’s why the Accelerated Wear Test is gaining traction. It simulates long-term surface wear through cycles of abrasion and repeated pendulum testing. Many materials lose their slip resistance after months of use or frequent cleaning.

SWISSGriP® Coatings stand out with superior wear resistance. Our solutions are tested with the accelerated wear method and consistently outperform many traditional tiles and floorings.

Why Choose SWISSGriP® Anti-Slip Coatings?

SWISSGriP® empowers you to meet or exceed required safety standards while preserving surface aesthetics. Our coatings provide a certified anti-slip solution that is independently tested for high-performance slip resistance.

Test Results
