Slip Resistance Testing for Decking Products

Ensuring Safety and Compliance: UKAS Accredited Slip Testing for Decking Samples in the Laboratory

Decking has become a popular choice for outdoor spaces, offering a versatile and aesthetically pleasing surface for both residential and commercial use. However, with the unpredictability of British weather and the potential for slippery conditions, ensuring the safety of decking materials is of paramount importance. This is where slip testing comes into play. To guarantee that decking surfaces meet the necessary safety standards, UKAS (United Kingdom Accreditation Service) accredited slip testing is crucial.

Why Slip Resistance Matters

Slip accidents are a common cause of injuries, and they can happen anywhere, including on decking surfaces. In the United Kingdom, legislation such as the Workplace (Health, Safety and Welfare) Regulations 1992 and the Building Regulations 2010 (Approved Document K) outline the importance of slip resistance in public and commercial spaces. Even in residential settings, the safety of decking cannot be overlooked.

Slip resistance is determined by assessing the surface’s friction and its ability to prevent slips and falls, especially in wet or icy conditions. To evaluate these factors accurately, UKAS accredited slip testing is essential.

The Importance of UKAS Accreditation

UKAS accreditation is a mark of quality and reliability in testing and calibration. When it comes to slip testing, UKAS accreditation ensures that the testing laboratory has met rigorous international standards for competence, impartiality, and performance. Decking manufacturers, builders, and property owners can have confidence in the accuracy and integrity of test results obtained from UKAS accredited laboratories.

The Slip Testing Process

UKAS accredited slip testing for decking samples follows a standardized procedure to ensure consistent and reliable results. Here’s an overview of the process:

  1. Sample Collection: Decking samples are collected, ensuring they represent the materials and conditions found in real-world settings.
  2. Sample Preparation: Samples may be conditioned to simulate environmental factors such as moisture, temperature, and contamination.
  3. Testing: Various testing methods are used to measure slip resistance, including the pendulum test, the ramp test, and the drag-sled test. Each method assesses slip resistance under different conditions and angles.
  4. Data Analysis: Test results are analyzed to determine the coefficient of friction (CoF) or slip resistance of the decking material. This data is crucial for compliance with safety regulations.
  5. Reporting: A comprehensive test report is generated, including detailed information about the sample, testing methods, results, and conclusions.

Benefits of UKAS Accredited Slip Testing for Decking Samples

  1. Safety Assurance: UKAS accredited slip testing provides confidence that the decking material meets safety standards, reducing the risk of slips and falls.
  2. Compliance: Compliance with regulations and building codes is essential for avoiding legal and liability issues.
  3. Quality Assurance: UKAS accreditation ensures the reliability and accuracy of test results, supporting product quality and performance.
  4. Peace of Mind: Property owners and builders can trust that their decking materials are safe and fit for purpose.


The safety of decking surfaces cannot be underestimated, especially in the ever-changing weather conditions of the United Kingdom. UKAS accredited slip testing plays a vital role in ensuring that decking materials meet the necessary safety standards and regulations. By investing in accredited testing, property owners, builders, and manufacturers can prioritize safety, compliance, and the well-being of all those who use these outdoor spaces.
