Zinc Whiskers
Zinc Whiskers are a phenomenon that occurs on the metal surfaces of raised access floors that have been electroplated with zinc for corrosion protection. The whiskers grow on the underside of the floor panels or the exposed surfaces of the structural components. The whiskers start off very small and over time the whiskers can grow to be several millimeters in length. When the whiskers break free they become airborne and can circulate freely throughout the building and get blown into any type of electrical equipment.
If a zinc whisker enters a circuit inside any electrical equipment, it can cause an electrical short. Zinc whiskers have caused many failures and power supply failures. Zinc whiskers are now a serious problem affecting many companies all over the world. Zinc whiskers have affected and will continue to affect the operation and cause large financial losses to thousands of companies worldwide.
ASP is Zinc Whisker Free
All ASP raised access floor products are designed to be zinc whisker free. All ASP panels, stingers, supports and pedestals are finished using the latest power coating technology. The epoxy powder coat is electro statically applied in a controlled environment and then baked to achieve the perfect fusion with the metal surface.
Structural Grading
One of the important criteria in the function of an access floor system is stability. This is measured by it's capability to support certain amounts of life and dead loads. The strengths of each system is classified by ability to support a desired static concentrated load applied over a 25 mm square indentor (to simulate legs of equipment) without having it's surface to deflect by more that 1/250 to 1/300 of it's pan.
ASP raised access floor systems are engineered to provide a high level of stability. Each product is carefully tested and rated according to the concentrated load achieved. ASP floors have a structural grading of ranging from 2.7 KN (600 lbf) to 24 NN (5400 lbf)
Dynamic Loading
Apart from being able to support the expected static loads, the performance of an access floor system is also measured by it's ability to withstand certain dynamic forces such as those applied by heavy rolling objects or impact of falling articles.
Durability
The steel components of all ASP floor systems are treated internally with a specialized phosphate coating and electro statically applied epoxy powder coating. The coating is then baked to fuse the power to the steel surface, resulting in a super tough finish.
Safety Factor
A controlled loading test is conducted where the access floor system is subjected to a static concentrated load at its weakest point until failure. The loading at that point of failure should be at least three times the expected strength, thus achieving a minimum safety factor of 3. ASP raised Access floors are designed to withstand more than three times the rated loading capacity
Fire Rating
All ASP products achieve all fire safety requirements which are tested in accordance with world wide testing standards. Testing has been conducted by the Australian Commonwealth Scientific and Industrial Research organization (CSIRIO), the forest institution of Malaysia (FIRM) and the Singapore Institute of standards and Industrial Research (SISIR)
Electro Static Control
An access floor system is considered good and practical only if it can be incorporated with various floor coverings to achieve an intended level of conductivity to suit the different applications which is generally classified as:
|
Level of Static Control |
Volume resistance |
|
Anti Static |
1 x 10 to 2 x 10 |
|
Static Dissipative |
1 x 10 to 1 x 10 |
|
Conductive |
0.5 10 to 1 x 10 |
ASP access Floor systems are designed to achieve these stringent requirements.
