Australian & International Standards Compliance 2018-2019
ASNZ 4422:2016 – Playground surfacing
The Standard gives a method for assessing the suitability of materials for use as soft fall. The Standard simply outlines a method of determining a head injury criteria (HIC) value, which is a calculation of the severity of a deceleration impact on a child’s brain during a fall.

ASNZ 4586:2015 – CombiLock – Wet Barefoot Ramp Slip Resistance Test – ATTAR, Melbourne
The CombiLock product was tested 26th September 2018 by ATTAR, Melbourne.
The wet barefoot ramp slip resistance test (AS/NZS 4586 Appendix C) uses a panel of the test surface which is constructed on a ramp large enough for a person to walk on. Two test people attach themselves to a safety harness, after bathing their feet for 10 minutes to soften the skin, walk bare foot on the test surface while the angle of the platform is increased until the limit of safe walking is achieved. This is generally when the test walker slips or feels that they will slip on the board. The angle that the limit of safe walking is obtained is known as the mean angle of inclination. Three calibration boards A, B & C are also tested, with the classification of the test panel based on the mean angle of inclination obtained in comparison with the calibration boards.

- Test 26th September 2018 – rating achieved AS4586:2013 Slip resistance classification – Appendix C Wet-Barefoot Inclining Platform Test.
- The tile achieved a ‘B’ Rating of 17°, however the CombiLock tile actually achieved 21.6° which is just short of the highest level of 24°.
Australian Wool Authority Authority – Standard Test Method for Tensile Properties of Plastics – Chlorine resistance
The AWTA provided a detailed analysis of the test results, and provided the following observation:
“The item is polypropylene. Whilst polypropylene is damaged by chlorinated solvents such as carbon tetrachloride it is unlikely to come into contact with that and as we have seen concentrations of chlorine in swimming pool water are unlikely to cause an issue. We can be confident about the 5 years from that point of view. A point to be mindful of however is that polypropylene does degrade due to the actions of UV light and would need to be adequately stabilized to be able to resist that. Suffice to say, that adequately stabilized polypropylene should have a good outdoor life.”
(Please note: CombiLock does contain a UV stabilizer)
