What are SSI and TCO?
SSI is the abbreviation for the name of a research institute in Sweden that performed some early research into monitor radiation . They developed some recommendations for maximum levels of radiation to be emitted by monitors within a book of ergonomic recommendations called MPR2. These recommendations were not so much health guidelines but rather descriptions of the current possible state of technology. SSI did provide a filter testing service which attempted to quantify the reduction, by a filter, in electromagnetic field radiation so that different filters could be compared in effectiveness. The test uses a field generator source. Their test is different than an MPR2 test which compares filter effectiveness when placed on an actual monitor. MPR2 recommendations have been surpassed by MPR3 and TCO recommendations. TCO is another organization that monitors standards in the workplace.
