Meeting the standard

SANS 52825:2009 Ultimate load Actual Carry Load/point load

t is apparent from the lead article on Access Flooring in this issue that there is considerable concern over the new SANS 52825:2009 Access

Flooring – based on the European EN standard that was adopted in the UK – as it does not meet the requirements of the local marketplace. Load testing is of particular concern, because the new standard falls short of that required by SABS 1549:1993 – the standard that has been used by the local manufacturers for years without any problems or failures. Jaco Boshoff says that at Solidfeel they have an in-house test facility, but

Ultimate load

“The CISCA testing standard and methodology is the international benchmark to which access flooring must conform, and CISCA and SABS 1549:1993 are very similar,” he says. “This means that products that do not conform to SABS 1549:1993 would not conform to CISCA, and this is exactly the problem we have with the SANS testing standard. There is also great confusion in the mar-
