26、an Standard specifies the sizing and constructional details of headforms for use in the testing of protective helmets. A recommended method of constructing wooden headforms is given in the annex. 2 Materials 2.1 Headforms for shock absorption and penetration tests with falling headform/helmet assemb

27、ly The headforms shall be made of a metal having a low resonance frequency but not below 3000 Hz. NOTE. A material with the following composition has been found suitable: magnesium/zirconium binary alloy with 0,3 % to 0,8 % zirconium, d = 1,79 kg/dm30,01 kg/dm3. Examples of designations: France: Max

28、ium II; United Kingdom: Alloy ZA; USA: Alloy KIA. 2.2 Headforms for shock absorption and penetration tests with fixed headform/helmet assembly The headforms shall be made of a rigid material which does not interfere with the measurements (e.g. wood as described in the annex). 2.3 Headforms for geome

29、tric examination or positional marking Any suitable material. 2.4 Headforms for other tests Where a test requires specific characteristics of the material (e.g. thermal or electrical conductivity or thermal capacity), these characteristics shall be specified in the appropriate standard. 3 General ch

30、aracteristics Headforms according to 2.1 shall have the following general characteristics. Code letter Inside circumference of helmet Mass mmkg A5003,10,10 E5404,10,12 J5704,70,14 M6005,60,16 O6206,10,18 The centre of gravity of the headforms shall be near point G on the central vertical axis z mm b

31、elow the reference plane (see figure 3 and table 3). Near its centre of gravity the headform shall contain a housing for a tridirectional accelerometer. 4 Sizing 4.1 Size codes The size codes used for headforms, related to the inside circumference of helmets and other measurements are listed in tabl

32、e 1. The circumference values refer to the internal circumference of the helmet measured at the headband level (AA9) as illustrated in figure 1. 4.2 Basic data The headform coordinate references are given in figures 2 and 3. Each datum level is quoted relative to the reference plane. 4.3 Dimensions

33、4.3.1 Above the reference plane The headforms shall comply with the appropriate dimensions given in table 2. The polar coordinates of the horizontal half-sections at each datum level referred to in table 2 are illustrated in figure 2. 4.3.2 Below the reference plane The headforms shall comply with t

34、he appropriate dimensions given in table 3. The polar coordinates referred to in this table are illustrated in figures 3a to 3c. 5 Marking All headforms shall be marked with: a) the basic plane as illustrated in figure 2; b) the longitudinal and transverse planes through the vertical axis; c) the si

35、ze code of the headform. NOTE. Other marking may be required by specific product standards. Table 1.
