Dust and Particle Protection
Industries – and people – depend on protective garments to keep processes and personnel safe. DuPont knows that one mistake can be critical, to your business or to a person’s life. It
To measure barrier performance against hazardous particulates, DuPont refers to EN ISO 13982-2, as prescribed within the Type 5 product standard. This test essentially determines the barrier
The Type 5 product standard allows for an inward leakage of up to 15% in 8 out of 10 suits tested, meaning that there is room for significant variation in barrier performance amongst coveralls that have been certified as meeting this standard. Therefore, when working with hazardous particulates, users should compare the performance of different suits and select the model most appropriate to their particular application.
When comparing the barrier performance of DuPont coveralls made from Tyvek®, microporous film (MPF) and SMS, under EN ISO 13982-2 test conditions, the Tyvek® models outperform those made from SMS and
The standard EN 1073-2 is used to define the requirements and test methods for determining the performance of protective clothing used in environments with radioactive particulates. The test method also measures the inward leakage of particulates into the whole suit, which is then expressed as its nominal protection factor (NPF). It comes as no surprise that the NPF increases with the body coverage provided by the Tyvek® model and the tightness and fit of its design: Tyvek® 500 Labo, Tyvek® 500 Xpert and Tyvek® 600 Plus all meet EN 1073-2 Class 2 (nominal protection factor > 50). In environments with a high concentration of radioactive particulates, the specifier will reduce risk by selecting a suit with a high
All of the above helps keep the worker safe. But Tyvek® suits protection works in two ways - also keeping processes free from particle contamination. Tyvek® is low-linting, as tested by BS 6909, a standard method for the generation and counting of the airborne linting propensity of fabrics in their dry state. By nature of its continuously strong, high-density polyethylene
