ZHTest Method: SATRA TM458
Qualitative Analysis of Silicone Content
March 2020
SCOPE
This method is intended to determine the presence of silicone on the surface of materials. This method is primarily applicable to polymeric gloves, although other materials and products may also be assessed using this method.
PRINCIPLE
The presence of silicone on the surface of materials can result in failure of solder bonds as well as adhesion failure due to reduced wetting, including the attachment of footwear sole units to upper and insole materials. It is therefore important to ensure that gloves that are worn to prevent the transfer of contamination from hands are not themselves contaminated with the presence of silicone on the surface of the glove.
The test specimen is extracted in petroleum ether and the resulting extract analysed by Fourier-Transform Infrared spectroscopy (FTIR). The infrared (IR) spectra obtained is assessed for the presence of peaks at around 1259 and 800 wavenumbers which indicate the presence of silicone.
