Foreword This standard specifies safety requirements and test methods for finger protection devices for hinged doors for intensive use. This standard is supplementary to -EN 16654:2015 Child protective products Consumer fitted finger protection devices for doors Safety requirements and test methods, intended for finger protection devices for use on doors in the domestic environment inside buildings. Finger protection devices for doors are used more intensively in professional work environments than finger protection devices in domestic environments. Professional work environments refer to child-care centres, schools, hospitals and similar environments where stricter safety requirements are applicable. This is the reason why supplementary requirements have been formulated for the requirements set on the test methods for finger protection devices for intensive use regarding: durability: doors inside a professional work environment are used more frequently than doors in the domestic environment inside buildings; resistance to compression, deformation and tension: to minimize the risk of accidents in locations where larger groups of children are present and less supervision is often the case. It was decided to make this standard applicable to a broader target group at risk than is covered by EN 16654:2015 as safety has the highest priority; ageing: this test is relevant in order to assure a durable quality for a large number of products (e.g. plastics that contain plasticisers). Since no standard for finger protection devices for intensive use is currently being developed at the European level, this supplementary Dutch standard has been developed to avoid confusion in the market. The Netherlands will investigate the interest to develop a European standard in due course. This standard was prepared by the standards sub-committee 'Fitted finger protection devices' and has been accepted by the standards committee 330 001 Child use and care products. At the time when the standard was published, the standards sub-committee comprised: A. J. Koole (Chair) VHS, Zoetermeer R. Marcus Arte Viva, Wijk bij Duurstede G. Buitenhuis Nederlandse Branchevereniging voor de Timmerindustrie (NBvT), Bussum J. Eykelhoff (Secretary) NEN, Delft 4
Finger protection devices for hinged doors for intensive use Safety requirements and test methods 1 Scope This standard specifies safety requirements and test methods for finger protection devices for hinged doors for intensive use. Finger protection devices in this standard are intended for use on both sides of doors, on the hinge side, to prevent crushing injuries to fingers. 2 Normative references The following reference documents are indispensable to the application of this document. For dated references, only the cited edition applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 16654:2015 3 Terms and definitions Child protective products Consumer fitted finger protection devices for doors Safety requirements and test methods For the purpose of this document, the following terms and definitions apply. 3.1 intensive use use where a door is opened and/or closed more than 50 times a day on average NOTE The following professional applications are examples of work environments where finger protection devices are used intensively: nurseries, hospitals, schools and other public buildings. 4 Requirements 4.1 General The finger protection device for intensive use shall comply with the requirements and test methods of EN 16654 and the supplementary requirements specified in this clause. 4.1.1 Ageing The finger protection device, except products where relevant safety parts are metal, is exposed to ageing by means of heat. One of the following options shall be chosen: the finger protection device is aged thermally at a constant temperature of 70 C ± 3 C in a climate chamber for 1 000 hours; the finger protection device is aged thermally at a constant temperature of 55 C ± 3 C in a climate chamber for 2 700 hours; 5
4.1.2 Durability The test method described in 5.4.1.1 of NEN-EN 16654 shall be used. Other than described in 5.4.1.1 of EN 16654, the requirement for the durability test shall be 200 000 cycles (+ 500). During the test, the finger protection device shall not break, have any visible cracks or permanent deformation, nor disengage from the test door and/or frame. The finger protection device shall be fully functional after the test. If any non-relevant parts become detached from the finger protection device during the test, they shall not fit wholly in the small parts cylinder described in 5.2.3 of EN 16654. 4.1.3 Accessibility The test method described in 5.4.2.1 of EN 16654 shall be used. Other than described in 5.4.2.1 of NEN-EN 16654, the push force to be applied shall be 50 N. When tested in accordance with the test described in 5.4.2.1 of EN 16654, the finger probe (see 5.2.2 of - EN 16654) shall not be crushed between the door and door frame. When the finger probe is removed: the normal operation of the door shall not be impaired; the finger protection device shall not be broken or have any visible cracks or permanent deformation; the finger protection device shall not disengage from the test door and/or the frame. NOTE For intensive use, it is assumed that the force of 25 N used in NEN-EN 16654, based on the mean index finger push force of children aged 2 to 5 years, is insufficiently safe. It has therefore been decided to use a force of 50 N, based on the mean index finger push force that children aged 6 to 10 years can apply. 4.1.4 Deformation The test method described in 5.4.2.2 of NEN-EN 16654 shall be used. Supplementary to 5.4.2.2 of NEN-EN 16654, the test shall also be carried out at a height of 750 mm (± 10 mm). NOTE 4.1.5 Resistance to tension The finger probe shall not be repositioned during the test. The test method described in 5.4.3.3 of NEN-EN 16654 shall be used. Other than described in 5.4.3.3 of EN 16654, the following tension shall be applied: 75 N (± 2 N) when the largest accessible dimension is 6 mm or less, or 150 N (± 2 N) when the largest accessible dimension is greater than 6 mm. Repeat the test cycle 50 times with a rest time of 20 s (± 2 s) after every cycle. The door shall be fully functional after the test; the finger protection device is not broken, does not have any visible cracks or permanent deformation and does not disengage from the test door and/or the frame. 6
5 Test sample and test sequence The length of the finger protection device to be tested shall be at least 150 cm. The finger protection devices are tested as follows: one finger protection device shall be subjected to the small parts test in accordance with 5.4.3 van NEN-EN 16654 and the resistance to tension test in accordance with 4.1.5; a second finger protection device is used for: an ageing test according to 4.1.1, and a durability test according to 4.1.2, and an accessibility test according to 4.1.3, a deformation test according to 4.1.4. The test shall be carried out in the sequence specified. 7
