Mechanical & Metallurgical Testing

  • Field Emission Scanning Electron Microsope(FESEM)

    It is an advanced analytical microscopy technique that can be used to resolve and analysenanosize structures to provide topographic, morphological and elemental composition at the surface of a sample.

    Applications:

    1.High resolution imaging for both conductive and non-conductive samples even without any conductive coating applied.
    2.Resolves nanostructure surface detail on both conductive and non-conductive samples.
    3.Measures size of particles on non-conductive fillers based on image.
    4.Identifies elements present on unknown/foreign material.
    5.Provides elemental composition of metallic materials.

          (Note: Elements with atomic number less than 11 cannot be quantified.)

STS conducts water efficiency testing on washing machine to Public Utilities Board of Singapore (PUB) requirements. Upon testing, STS assist the manufacturers and traders to apply for PUB Water Efficiency Labels. Upon successful registration with PUB, suppliers/retailers will fix the Water Efficiency label for each of their washing machine model displayed for sale or supply. The Water Efficiency label will also be prominently fixed to each model or on its packaging at the point of sale or supply or offer for sale or supply.
