SABS Test Waterproof• Test method is for the worst case scenario i.e. Cape Town 1,000-mm rainfall per annum with a wind speed of 30 metre/second conducted over a 24- hour period.
SABS Test Soft Body Impact• A 30 kg bag swings to impact the wall 900 mm above the floor height to access the serviceability criteria• 1800 mm above the floor height to access the safety criteria.• Two impacts of the bag where executed on the exterior wall surface for each of the above criteria and the wall was inspected after each impact for any sign of cracks, damage or collapse – none.
SABS Test Chisel Impact• After two impact of the chisel from a height of 375 mm above the floor height a slight indentation was visible. The depth of the indentation was less than 3 mm.
SABS Test• All test conducted by the South African Bureau of Standards, have been executed on a 100 mm (4 inch) wall as this is an acceptable norm for in situ walls and is also the standard applied to low cost housing units.• Thermal conductivity of 100 mm moladi wall = 0,54 W/m.K
