18、dwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on
19、that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this do
20、cument and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Direct
21、ives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the developm
22、ent of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO spec

26、15PPE for firefighters Test methods and requirements for PPE used by firefighters who are at risk of exposure to high levels of heat and/or flame while fighting fires occurring in structures Part 5: Helmets1 ScopeThis part of ISO 11999 specifies the minimum design and performance requirements for he
27、lmets as part of personal protective equipment (PPE) to be used by firefighters, primarily but not solely to protect against exposure to flame and high thermal loads.NOTE A Type 1 helmet is similar to helmets for fighting fires in structures according to EN 443:2008. A Type 2 helmet is similar to he
28、lmets used for fighting fires in structures according to NFPA 1971:2013. However, following ISO 11999-1, all parts of heat and flame resistance requirements are consistent with each other, therefore heat and flame tests consistent with requirements for clothing given in ISO 11999-3.2 Normative refer

37、and Proximity Fire Fighting3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 11999-1 apply.4 Helmet requirements4.1 GeneralHelmets shall consist of at least the following assembled components:a) Shell (area 1a according to EN 443:2008).b) Energy absorbi
38、ng system. Retention system. The retention system shall include a chinstrap having a minimum width of 19 mm.c) Neck protector (Optional for Type 1 helmets, area 3a according to EN 443:2008).d) Ear covers (Optional for Type 1 helmets, area 1b according to EN 443:2008).e) Faceshield or goggles or both
39、 (Optional for Type 1 helmets, area 3b or area 2 according to EN 443:2008). Where a faceshield is selected, the faceshield shall be attached to and tested with the helmet. Where goggles are selected, the goggles shall be permitted to be unattached, not assembled, to the helmet. Where they are attach
40、ed to the helmet, they shall be tested with the helmet. Where they are not attached, they shall be removed from the helmet before it is tested.4.1.1 FitThe fit of the helmet shall be adjustable laterally, in order to improve the wearing comfort and the helmet efficiency. This adjustment shall be eas
41、ily feasible by the wearer without the use of tools. It should be possible for the wearer to remove the helmet by releasing the chinstraps, using one hand wearing a structural firefighting glove.When this adjustment covers several size of head circumference, the relevant instructions shall be given
42、in the information supplied by the manufacturer.4.1.2 Protrusions and sharp edgesThere shall be no sharp edges, roughness or projection on any part of the helmet. Projections intruding more than 5 mm from the shell interior surface and above the test line, shall not be acceptable unless covered by p
43、rotective padding. Projections above the test line shall be impacted directly over the 2 ISO 2015 All rights reservedBS ISO 11999-5:2015ISO 11999-5:2015(E)position of the internal projection in accordance with 4.4.7, and the laboratory shall assess that the projection did not make contact with the h
44、eadform.Rigid internal projections below the test line and above the reference plane shall not be able to touch the head of the wearer when the helmet is normally affixed to the head.The profile at the front of the helmet shall not prevent the wearing of spectacles or goggles as specified by the hel
45、met manufacturer.4.1.3 ReinforcementThe shell construction shall be uniformly reinforced. This does not exclude a gradual increase of the shells thickness or of the grooves or fixation devices of the harness or of the accessories, but it does exclude every other localized reinforcement.4.1.4 Replace
46、ment components and accessoriesThe fitting and/or replacement of any interchangeable parts or accessories shall not impair the function and/or safety of the helmet. All accessories and their respective replacement procedures shall be given in the information supplied by the manufacturer. No openings
47、 shall penetrate the helmet shell other than those provided by the manufacturer for mounting energy absorbing systems, retention systems or accessories.Faceshields shall not be considered as accessories and along with neck protectors (where fitted) shall be considered as fixed sub-components of the
48、helmet assembly.4.1.5 Neck protector and ear coversType 2 helmets shall cover the wearers neck and ears, or shall have neck protector and ear covers that cover the wearers neck and ears. The helmet or the helmet with neck protectors and ear covers shall provide at least the following coverage.The he
49、lmet, or the helmet with neck protector and ear covers, shall be donned in the proper wearing position as specified by the manufacturer on an EN 960:2006 headform 575 according to its positioning index. The helmet positioning index shall be the vertical distance, as specified by the manufacturer, from the lowest point of the brow at the lateral midpoint of the helmet to the basic plane of the EN 960:2006 headform 575 with the helmet firmly positioned on the headform.
