MATEST, represented in Australia by TestEquip , has released its new skid resistance tester.

The apparatus is suitable for both site and laboratory applications for performing two types of tests:

1. For measuring pavement (road asphalt) surface frictional and skid resistance properties.

2. For polished stone value tests on aggregates (curved specimens) from accelerated polishing tests.

The skid tester is also suitable to perform tests on:

* Natural stones conforming to EN 1341, 1342.

* Concrete block pavers conforming to EN 1338.

The tester measures the energy loss when a rubber slider edge is propelled over the surface under test.

The slider lifting device is incorporated in the pendulum base assuring accurate adjustment operations. The height adjusting system is simple and reliable.

The pointer, made from light alloy, has extremely low frictions granting high precision results.

The release mechanism of the pendulum arm has an original solution reducing the friction to minimum for better accuracy.

The skid tester is supplied complete with:

* Additional incorporated scale for tests on Polished Stone Value specimens.

* Rule, plexiglass made, for sliding length verification.

* Thermometer range –10 to +110°C. for surface temperature measurement.

* Stool, wash bottle, bristle, tool set for machine use.

* Carrying case.

* Calibration Certificate conforming to EN 1097-8.l

This tester meets all of the following standards:- AS/NZS 4586:1999, EN 1097-8 / EN 1338, 1341, 1342 / EN 13036-4 / ASTM E303 / BS 812:114 / CNR N. 105, 140 / NF P18-578, P18-575 / NLT 174.

For Australian pedestrian slip resistance standards, architects, specifiers and stone merchants should only need to be familiar with Standards Australia Handbook 197, an introductory guide to the slip resistance of pedestrian surface materials.

This deals with the selection of products based on the wet slip resistance classifications that are obtained according to the test methods that are published in AS/NZS 4586, slip resistance classification of new pedestrian surface materials. HB 197 was also written to help with the transition from AS/NZS 3661.1,
