1、Designation: F1446 13F1446 15 An American National StandardStandard Test Methods forEquipment and Procedures Used in Evaluating thePerformance Characteristics of Protective Headgear1This standard is issued under the fixed designation F1446; the number immediately following the designation indicates
2、the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThese test methods specify equipment and procedu
3、res used for testing protective headgear.Individual ASTM performance standards (standard specifications) will use these procedures andequipment. Test conditions, pass-fail criteria, and other performance requirements will be specified inthe individual performance standards, tailored to the needs of

Terminology4.1 Definitions:4.1.1 basic plane, nan anatomical plane (Frankfort Horizontal Plane) that includes the superior rim of the external auditorymeatus (upper edge of the external openings of the ear) and the inferior margin of
18、the orbit (the lowest point of the floor of theeye socket). The headforms are marked with the basic plane (see Figs. 1 and 2).4.1.1.1 DiscussionThe headforms are marked with the basic plane (see Figs. 1 and 2).4.1.2 coronal plane, nan anatomical plane perpendicular to both the basic and midsagittal
19、planes and passing through thesuperior rims of the right and left auditory meatuses. The transverse plane corresponds to the coronal plane (see Figs. 1 and 2).4.1.2.1 DiscussionThe transverse plane corresponds to the coronal plane (see Figs. 1 and 2).4.1.3 field of vision, nangle of vision as measur

Helmets shall be tested on the largest and smallest size test headforms on which they fit. When mu
21、ltiple headform sizesare required, each test set of helmets will include at least one extent of coverage, vision test, retention test, and impact test on eachspecified headform size. “Fit” means that it is not physically difficult to put the helmet on the larger headform and that thehelmetshelmets c

For helmets equipped with adjustable fitsystems, the headform sizes are determined by the fit at the smallest and largest limits of the adjustment.4.1.5 helmet, na protective device worn on the head in an effort to reduce or minimiz
