4 40 STANDARDS AND CERTI FICATIONS G ENERAL REQU I REMENT S STANDARD : EN I SO 2 1 420 : 2020 The European standard EN 420:2003+A1:2009, replaced in 2020 by EN ISO 21420: 2020, defines the general requirements and corresponding test procedures for gloves , design and manufacture, resistance of glove materials to water penetration, harmlessness (pH value within the range 3,5 e 9,5, Chromium VI < 3 mg/Kg, extractable protein content, Azo dyes, DMFa < 1000 mg/Kg, PHAs < 1mg/ kg), comfort, marking and information provided by the manufacturer applicable to all protective gloves. The glove is an individual protection product designed to protect the hand and its various parts. The glove may also cover part of the forearm and arm. The performance index, normally indicated by a number between 0 and 4 (5 in the case of cutting), indicates how well the glove performs in a given test. This ranking then makes it possible to classify the results of the test. Level 0 indicates that the glove has not been tested or has not met the minimum requirements. A performance level X indicates that the test method is not suitable for the tested glove sample. A high number normally corresponds to a high performance level. The standard can also be applied to arm and forearm protection sleeves. SPEC I FIC STANDARDS MECHAN I CAL R I SKS EN 388 : 201 6+A1 : 201 8 This standard specifies the physical and performance requirements as well as the test methods for protective gloves against mechanical risks: a) Abrasion resistance (0-4): Number of cycles required to abrade a hole with abrasive paper (Klingspor) in a round sample of glove material under constant pressure and movement. b) b) Resistance to cutting by blade using the Coup test (0-5): Number of cycles required to cut a sample by using a stainless steel circular blade at a constant speed and reduced force of 5 newtons (approx. 510 g). An ISO 139997 test is performed on materials that make the blade blunt, after a certain number of cycles without cutting, which becomes the reference of resistance to cutting. c) Resistance to tearing (0-4): The force required to cause the propagation of a tear in a rectangular glove sample with an initial incision, up to a maximum force of 75N (approximately 7.6 kg). d) Resistance to perforation (0-4): The force required to pierce through the sample using a standard size steel bit at a constant speed of 10 cm/min. e) Resistance to cutting by blade using ISO test (A - F): The force in newtons (N) required to cut a sample using a straight blade with a particular cutting test machine (TDM). This test is optional, unless the blade in the Coup test becomes blunt, thus making it the reference for cutting resistance. To each value a letter is assigned as follows: f) Resistance to impact (P): For impact-resistant protective gloves, it measures the force dissipation from the protective area following the impact with a domed anvil at an impact energy of 5 joules. The test complies with the impact protection test for motorbike protective gloves of standard EN 13594:2015. If the test is successful a 'P' is added, otherwise nothing is indicated.
