Flammability Test

Result

Flame-Resistant Polycarbonate (FRPC)Standard result – UL94 V-O at 3mm, rated ‘self-extinguishing’FRPC seamless mesh has been tested to:

  • ISO 9705 Group 1-S Pass.
  • AS 1530 pt2, achieving a Flammability Index result of (FI) = 6.
  • NFPA 701 Test Method #2 – Pass.
  • DIN 4102.2 – Pass.
  • IMO A 652 Fire test for upholstered furniture.
  • ISO 15025 2000 (E) Protective Clothing – Protection against heat and flame – Test for limited flame spread

Sunlight (UV) and exterior weathering

Result

Independently lab tested by Building Research Association of New Zealand (BRANZ).Results show minimal structural/tensile deterioration of the mesh after 2000 hours of continuous testing (equivalent to approximately 5+ years exterior exposure in New Zealand’s harshest UV conditions – some of the toughest in the world).All colours are light fastened, mineral-based pigments to maintain colour and recyclability.Yellowing of the mesh, particularly with light and translucent colours is noticeable after 500 hours.

Darker solid colours are less susceptible to yellowing and structural deterioration (in approved applications KML will provide a 10-year warranty against both visual and structural deterioration).

UV protective hard-coating available on requst. Results show virtually no visual or structural deterioration after 1500 hours testing (equivalent to approximately 8–10 years exterior exposure).

Tensile strength and Impact resistance

Result

Note: The accumulated strength of seamless mesh increases proportionately with the size of the panel. Astron burst testing with a point load area of approx. 32mm (1.5”) on small 140 x 140mm (5 1/2” x 5 1/2”) samples show a peak resistance of 279kg (615lb).When drop testing on to a 1.5m x 2.4m (4’ x 8’) mesh panel, it repetitively withstood a free-falling 80kg (175lb) weight from 2.5 metres (8’).This equates to an impact force of 6500N (650kg or 1,300lbs).Suitable for use as balustrade infill to New Zealand Building Code NZBC F4 safety from falling.Exceeds required strength loads prescribed in AS/NZS 1170.1 for balustrades including C5 Crowd loadings.

Drag coefficient (used for calculating wind loadings)

Result

Cd = 0.8, which is 40% less than an equivalent two-dimensional or woven mesh.Full wind tunnel test results for all angles available.
