Technical Data
PROFILE AND THICKNESS (not to scale):
WEATHERING RESISTANCE
S.F.M. Post material formulation (in the extruded weatherboard Supa-Clad I.P.) have been subjected to outdoor weathering tests at Allunga Exposure Laboratories, Townsville, with satisfactory results and are continuing in accordance with A.S. AK CK24, Part 1 - 1972 by the Allunga Exposure Laboratory.
HEAT RESISTANCE
S.F.M. Posts have been conditioned in an oven for 2 hrs at 62o C and have proved capable of straightening themselves within 30 secs. when bent 90o for each 4 bends. The tests were completed within 2 mins. of removal from the oven.
COLD RESISTANCE
a) S.F.M. Posts have been conditioned over-night in ambient conditions not exceeding 2o C and have proved capable of straightening themselves instantly when bent for each of 4 bends. The tests were conducted at ambient temperature of 1o C.
b) A steel ball weighing 1kg. was dropped a distance of 1500mm through a vertical frictionless guide to impact the surface of the S.F.M. which was in a horizontal position beneath the guide. The test was repeated 5 times and was concentrated near the middle of the post. The tests were conducted in a continuing ambient temperature of 1o C.
GROUND WATER RESISTANCE
S.F.M. Posts are totally impervious to water regardless of ph value, or duration of immersion.
HYDRO CARBON RESISTANCE
S.F.M. Posts have been immersed totally in commercial grade petrol for periods of one hour. No change in appearance or properties obtained.
FIRE RESISTANCE
S.F.M. Posts have been tested for 2000 seconds (33mins), supported 60mm below a 2000 watt silica rod element. The product did not ignite, or show any trace of discolouration.
FLAMABILITY
S.F.M. Posts do not support combustion when the source of flame is removed, the material will cease burning.
Specifications
INSTALLATION
NON-DRIVEABLE POSTS
S.F.M. Posts may be supplied with a 25mm hole to suit an anchor rod in a transverse horizontal position, to resist extraction
DRIVEABLE POSTS
S.F.M. Posts are available with a tongue to resist extraction, the bottom end being square cut (see drawing) or pointed (not illustrated) to order, to assist driving -being ideal for temporary locations
RETENTION DEVICES
RETRO - REFLECTIVE
If specified each post can be supplied with two retro reflective surfaces, one red and one white, to the dimensions required. The retro-reflective materials complies with the requirements of AS 1906—part 1 1981 for class 1A materials. Alternatively, if ordered, S.F.M. Posts can be supplied with Disc Base Formed “seating” for corner Cube Type Delineators
VEHICLE IMPACT
An S.F.M. Post was subjected to 10 impacts head on into traffic, at speeds of 100Kph and 5 impacts at an angle approximately 75o to the traffic face at speeds of 90Kph. The post remained capable of self erecting to vertical and remained serviceable after these tests.
FIELD RIGIDITY
a) Dynamic Test - S.F.M. Posts have been observed not to deflect more than 75mm from the rest position nor oscillate unduly under a gusty wind load at c.a. 50Kph.
b) Static Test - A 1kg load was applied at right angles and centrally to the top of the post in its weakest direction. The post did not deflect more than 75mm from its rest position.
ANCHOR ROD
All sizes shown are nominal 140mm x 25mm PVC
Providing maximum retention capability
DIMENSIONS
a) Width: S.F.M.’s have a minimum width of 105mm facing traffic over the entire length.
b) Length: S.F.M.’s are supplied + or - 2.5mm of the length specified by an Authority.
Stock Lengths: 1.4 metres or length to order.
c) Thickness: 4mm stock size.
IDENTIFICATION
When specified or requested S.F.M. Posts can be printed with a brand name, manufacturers name, and/or month/year of manufacture, and/or Authority’s Initials.
