SIST EN 14052:2012
EN 14052:2012 (E) 5 Introduction Advances in materials and design methods have allowed helmets to be developed that have a higher performance than other types of general industrial helmets. Helmets complying with European Standards offer a suite of head protection devices for general industrial use: the industrial bump cap meeting the requirements of EN 812, the industrial safety helmet meeting the requirements of EN 397, and the high performance industrial helmet meeting the requirements of EN 14052. Industrial bump caps are intended to provide protection to the wearer against the effects of striking his head against hard, stationary objects with sufficient severity to cause lacerations or other superficial injuries. They are not intended to provide protection against the effects of falling or thrown objects, or moving or suspended loads. In addition to the mandatory requirements the caps may have shock absorption properties at low temperatures, be flame resistant and have electrical properties. Industrial safety helmets are intended primarily to provide protection to the wearer against falling objects and are not intended to provide protection against off crown impacts. The mandatory requirements for the helmets includes for them to have flame resistant properties. In addition to the mandatory requirements the helmets may have shock absorption properties at very low temperatures and very high temperatures, have electrical insulation properties, have lateral deformation properties, and provide protection against molten metal splash. The high performance industrial helmet offers greater protection from falling objects, protection from off crown impacts and protection from penetration by a flat blade striker. It also includes a retention system that meets mandatory requirements for system release and system effectiveness properties. The helmet has the same flame resistant properties as the industrial safety helmet and offers the same optional protection against other risks with the exception of lateral deformation. The technical committee, which has prepared this European Standard, realizes that mechanical rigidity is of importance for the wearer’s safety. At the time, the standard was prepared no valid test method was recognized. For that reason, no requirements concerning mechanical rigidity have been introduced. Designers are encouraged to accommodate ear, eye, and respiratory protection into the helmet design where required. When possible the design and performance of such additional protective functions should be in accordance with the relevant European Standard for these products. When this is not possible, the manufacturer will draw attention to any compromises by means of information supplied with the helmet. The wearing of a helmet meeting the requirements of this European Standard will reduce, but not eliminate, the likelihood of head injury. There are limits to the amount of protection that can be provided. In the workplace, it remains the responsibility of the employer to judge the helmet’s suitability for their particular purpose.

EN 14052:2012 (E) 10 When tested for penetration in accordance with 6.5, the requirement given in 5.2.2 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.7. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. 5.3.3 Resistance to radiant heat When tested for shock absorption in accordance with 6.4, the requirement given in 5.2.1 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.8. When tested for penetration in accordance with 6.5, the requirement given in 5.2.2 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.8. In addition, the temperature measured at the surface of the test headform shall not rise by more than 25 °C above the prevailing ambient laboratory temperature. No part of the helmet shall melt to such a degree as to cause dripping of the material. Any damage or distortion exhibited by the helmet shall not adversely affect its operational capability. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. 5.3.4 Electrical properties When tested by all three of the methods given in 6.10, the leakage current shall not exceed 1,2 mA. NOTE 1 This requirement is intended to provide protection to the wearer against short term, accidental contact with live electrical conductors at A.C. voltages up to 440 V. NOTE 2 Test 1 is intended to simulate closely the in-use situation - that is, the leakage current to the wearer via a live conductor touching the outer surface of the helmet. NOTE 3 Test 2 is dependent upon the transverse resistance of the helmet section. This effectively precludes the use of metal in, and of holes passing through, the helmet section. NOTE 4 Test 3 is dependent only upon the surface resistance of the helmet, and effectively precludes the use of a conductive surface (e.g. metal electro-plating). This test was deemed to be necessary in order to obviate the danger to the wearer should he try to remove a helmet whose outer surface was in contact with a live conductor. Helmets claimed to meet this requirement (for all three electrical properties tests) shall state this fact on the label attached to the helmet, in accordance with 7.1.2. 5.3.5 Molten metal splash When tested in accordance with 6.11, the helmet shall not: a) be penetrated by the molten metal; b) show any deformation, measured at right angles to the base plane of the helmet, greater than 10 mm; c) burn with the emission of flame after a period of 5 s has elapsed after the pouring of molten metal has ceased. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. SIST EN 14052:2012
EN 14052:2012 (E) 11 6 Testing 6.1 Samples Helmets shall be submitted for testing in the condition in which they are offered for sale, including any requisite holes or other means of attachment, for any item(s) as defined in 3.6 or 3.7. If any items as defined in 3.6 and 3.7 are submitted with the helmet for testing, the helmet shall be tested with all the items fitted and without the items fitted. NOTE No helmet that has been subjected to testing should be offered for sale. The minimum number of samples and conditions per helmet type required to test to all performance requirements of this European Standard is as follows: (i) Mandatory tests: 2 helmets for shock absorption (6.4) test at + 50 °C; 2 helmets for shock absorption (6.4) test at – 10 °C; 2 helmets for shock absorption (6.4) test following water immersion; 2 helmets for shock absorption (6.4) test following artificial ageing; 2 helmets for resistance to penetration (6.5) test at + 50 °C; 2 helmets for resistance to penetration test (6.5) at – 10 °C; 2 helmets for resistance to penetration test (6.5) following water immersion; 2 helmets for resistance to penetration test (6.5) following artificial ageing. If the helmet manufacturer's instructions state that a chin strap is an essential part of the helmet, required to retain the helmet on the head, then a chin strap shall be supplied with each helmet to be tested for impact protection or resistance to penetration. 1 helmet for retention system release test (6.6) (if applicable) at + 50 °C; 1 helmet for retention system release test (6.6) (if applicable) at – 10 °C; 1 helmet of each size for retention system effectiveness test (6.7); 1 helmet for flame resistance test (6.8).

At the time the standard was prepared no valid test method was recognized. For that reason no requirements concerning mechanical rigidity have been introduced. Designers are encouraged to accommodate ear, eye, and respiratory protection into the helmet design where required. When possible the design and performance of such additional protective functions should be in accordance with the relevant European Standard for these products. When this is not possible, the manufacturer will draw attention to any compromises by means of information supplied with the helmet. The wearing of a helmet meeting the requirements of this European Standard will reduce, but not eliminate, the likelihood of head injury. There are limits to the amount of protection that can be provided. In the workplace, it remains the responsibility of the employer to judge the helmet’s suitability for their particular purpose. kSIST FprEN 14052:2011

When tested in accordance with 6.7, the helmet shall not fall off the head of more than two test subjects. 5.2.5 Flame resistance When tested in accordance with 6.8, the materials tested shall not burn with the emission of flame after a period of 5 s has elapsed after removal of the flame. 5.2.6 Label The label(s) which may be attached to the helmet in accordance with 7.1.2, shall remain attached and legible on each sample helmet, following the appropriate conditioning in accordance with 6.2.2 or where applicable 6.2.6, 6.2.3 or where applicable 6.2.7, 6.2.4, 6.2.5, and where applicable 6.2.8. 5.3 Optional requirements 5.3.1 Performance at lower temperatures When tested for shock absorption in accordance with 6.4, the requirement given in 5.2.1 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.6. When tested for penetration in accordance with 6.5, the requirement given in 5.2.2 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.6. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. 5.3.2 Performance at higher temperature When tested for shock absorption in accordance with 6.4, the requirement given in 5.2.1 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.7. kSIST FprEN 14052:2011
FprEN 14052:2011 (E) 10 When tested for penetration in accordance with 6.5, the requirement given in 5.2.2 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.7. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. 5.3.3 Resistance to radiant heat When tested for shock absorption in accordance with 6.4, the requirement given in 5.2.1 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.8. When tested for penetration in accordance with 6.5, the requirement given in 5.2.2 shall be satisfied by two helmets which have been conditioned in accordance with 6.2.8. In addition, the temperature measured at the surface of the test headform shall not rise by more than 25 °C above the prevailing ambient laboratory temperature. No part of the helmet shall melt to such a degree as to cause dripping of the material. Any damage or distortion exhibited by the helmet shall not adversely affect its operational capability. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. 5.3.4 Electrical properties When tested by all three of the methods given in 6.10, the leakage current shall not exceed 1,2 mA. NOTE 1 This requirement is intended to provide protection to the wearer against short term, accidental contact with live electrical conductors at A.C. voltages up to 440 V. NOTE 2 Test 1 is intended to simulate closely the in-use situation - that is, the leakage current to the wearer via a live conductor touching the outer surface of the helmet. NOTE 3 Test 2 is dependent upon the transverse resistance of the helmet section. This effectively precludes the use of metal in, and of holes passing through, the helmet section. NOTE 4 Test 3 is dependent only upon the surface resistance of the helmet, and effectively precludes the use of a conductive surface (e.g. metal electro-plating). This test was deemed to be necessary in order to obviate the danger to the wearer should he try to remove a helmet whose outer surface was in contact with a live conductor. Helmets claimed to meet this requirement (for all 3 electrical properties tests) shall state this fact on the label attached to the helmet, in accordance with 7.1.2. 5.3.5 Molten metal splash When tested in accordance with 6.11, the helmet shall not: a) be penetrated by the molten metal; b) show any deformation, measured at right angles to the base plane of the helmet, greater than 10 mm; c) burn with the emission of flame after a period of 5 s has elapsed after the pouring of molten metal has ceased. Helmets claimed to meet this requirement shall state this fact on the label attached to the helmet in accordance with 7.1.2. kSIST FprEN 14052:2011
