![]() The thickness of each sample is then measured and compared to the initial thickness to determine a value. After conditioning for a minimum of 16 hours, the samples are subjected to a load whose tensile speed must be 500mm/min. Test method: samples are cut into the shape of “dumb-bells” or “dog-bone” at the palm, back of the hand or cuff in the longitudinal axis of 13 gloves from the same batch.A physical deformation test evaluates the amount of force applied to a glove sample until it tears. The tensile strength is expressed in Newtons (N) or in megapascals (MPa). Therefore, it is useful to refer to the results of the elongation at break and tensile strength tests under the nearest relevant European standard ( EN 455-2:2015 for medical gloves) or the American standard ASTM D412-16 (supplemented by ASTM D573-04(2019) for tests after aging). Surprisingly, measurement of physical properties is not a requirement for PPE-type ” protective gloves against chemicals and micro-organisms” (as defined in ISO 374-1:2016+A1:2018 “Terminology and performance requirements”). To minimize the risk of tearing, it is advisable to choose gloves based, among other things, on their tensile strength data and elongation properties. “Natural latex is usually of higher elasticity than nitrile or vinyl but its protective qualities against chemicals splashes may be lower.” In this respect, it is worth noting that: To prevent disposable gloves from tearing it is necessary to ensure that the selected gloves will withstand elongation especially during donning, without altering the qualities of protection, comfort and fit.ĬHECKING THE TENSILE STRENGTH OF SINGLE-USE GLOVESĭepending on the glove material, its physical properties will be different and so will its protective properties. Indeed, a glove that tears no longer effectively protects the user. When choosing a single-use glove, considering its tensile strength, elongation properties or even its potential for tearing whilst being stretched may be relevant. It is therefore essential to ensure the protection of workers by providing them with disposable gloves adapted to the tasks being undertaken. Thus, wearing disposable gloves is essential for many applications in the laboratory, cleanroom, industrial or medical sectors. The skin is an important route for penetration of chemicals or microbiological agents that are potentially dangerous to human health.
