Mechanical Performance Testing in accordance with SANS 613
Test for air leakage, wind deflection, water penetration and structural strength of fenestration systems.
|Air leakage||The air leakage through the specimen should not exceed 2 L/s/m2 under a pressure difference of 75 Pa.|
|Wind deflection||Maximum wind deflection allowed is 1/175 of span or 20 mm under a uniform load of 1000 Pa – 3000 Pa.|
|Water penetration||There should be no leakage when subjected to a flow of 0.05 l/s.m2|
|Structural strength||There must be no structural failure or permanent deformation with a load of 50% more than the intended load.|
Rotatable Guarded Hot Box Testing
The Rotatable Guarded Hot Box (RGHB), located on the CSIR campus in Pretoria, is a testing facility for determining the heat transmission values (U-factor in W/m2.K) of any building’s envelope system for any angle of application in accordance with ASTM C 1199 and ASTM C 1363. SANS 10400-XA sets a target for reducing energy usage in buildings. Therefore the RGHB is an attempt to help the construction industry reduce its energy usage.
