10、mage control/fire fighting. 2.2.2 Retention system. Retention system shall include a suspension system, nape device, and chin strap. 2.2.2.1 Suspension system (energy absorbing system, headband, and crown strap). The design shall incorporate a removable/replaceable energy absorbing system containing

11、 an adjustable, ratchet type, cushioned head band/crown strap system. The crown straps shall possess a protective interface, so that the intersection of the straps does not rest directly on the user. This may be achieved with a cushioned headband liner or padding attached directly to crown strap int

12、ersection. All crown straps shall be positively attached to the suspension system. 2.2.2.2 Nape device. The nape device, located below the Bitragion Inion Arc, shall be used for helmet retention. 2.2.2.3 Chin strap. The chin strap shall consist of an aramid webbing containing a high temperature resi

13、stant, quick release fastener. The chin strap shall be attached to the outer shell. 2.2.3 Ear cover. The ear cover shall be constructed of a polybenzimidazole/Kevlar outershell material, moisture barrier, and liner, meeting a Thermal Protection Performance (TPP) rating of at least 20. TPP testing sh

14、all be conducted in accordance with NFPA 1971. The liner shall consist of meta or para-aramid and/or polybenzimidazole fiber or any combination thereof. The ear cover shall either be bound on all edges with the base fabric, or raw edges turned in and stitched. No raw or serged edges shall be visible

15、. The ear cover shall have a chin strap that is positively secured on one side and closed by means of hook and pile fastener tape to the other side.

16、h of the ear cover measured from bottom edge of impact liner to bottom edge of ear cover shall be no less than 7 inches. 2.2.4 Face shield. The face shield shall be manufactured from a high heat material that has a heat deflection temperature of 325 F at 264 psi, 0.25-inch specimen, when tested in a

17、ccordance with ASTM D648. The face shield shall be either 4 or 5 inches in depth. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-A-A-59798 2.3 Performance characteristics. 2.3.1 Penetration/impact resistance. The helmet shall be tested in accordan

18、ce with the physical penetration resistance test of NFPA 1971, after exposure to heat as outlined in NFPA 1971 for heat and thermal shrinkage resistance test, within 305 seconds after removal from heat source. The following exceptions shall apply: a. The drop height shall be 8 feet for the top plane

19、 and 4 feet for the side plane. b. During the top plane penetration test, the impact transmission force shall be measured. The electronic force measuring system shall be in accordance with the test method for top impact resistance of NFPA 1971. A single top impact force exceeding 850 pounds shall co

20、nstitute a failure. c. Two determinations shall be made for both top- and side-impact testing, one determination per helmet. d. The weight of the penetration test striker shall be 6 pounds, 10 ounces0.1 pound. The point of the striker shall have an included angle of 600.5 degrees and a cone altitude

21、 or height of not less than 1.5 inches. The radius of the striker point shall be 0.01970.004 inch. The hardness of the striking tip shall be a minimum of 60 Rockwell (Scale C). 3.
