67 Pa. Code § 107.6. Preliminary test procedures.

§ 107.6. Preliminary test procedures.

 Before subjecting a helmet to the testing sequence specified in §  107.7 (relating to test conditions), prepare it according to the following procedures.

 (a)  Reference marking. Reference marking shall be conducted as follows:

   (1)  Use a reference headform that is firmly seated with the basic and reference planes horizontal. Place the complete helmet to be tested on the reference headform of the largest size specified in Appendix A whose circumference is not greater than the internal circumference of the headband when adjusted to its largest setting or, if no headband is provided, to the corresponding interior surface of the helmet.

   (2)  Apply a 10 pound static load normal to the apex of the helmet. Center the helmet laterally and seat it firmly on the reference headform according to its helmet positioning index.

   (3)  Maintaining the load and position described in paragraph (2), draw a line, hereinafter referred to as ‘‘test line,’’ on the outer surface of the helmet coinciding with portions of the intersection of that surface with the following planes, as shown in Figure 2 of Appendix A:

     (i)   A plane 1 inch above and parallel to the reference plane in the anterior portion of the reference headform.

     (ii)   A vertical transverse plane 2.5 inches behind the point on the anterior surface of the reference headform at the intersection of the midsagittal and reference planes.

     (iii)   The reference plane of the reference headform.

     (iv)   A vertical transverse plane 2.5 inches behind the center of the external ear opening in a side view.

     (v)   A plane one inch below and parallel to the reference plane in the posterior portion of the reference headform.

 (b)  Helmet positioning. Prior to each test, fix the helmet on a test headform in the position that conforms to its helmet positioning index. Secure the helmet so that it does not shift position prior to impact or to application of force during testing. In testing as specified in §  107.7(a) and (b), place the retention system in a position such that it does not interfere with free fall, impact or penetration.

 (c)  Conditioning. Immediately prior to conducting the testing sequence specified in §  107.7, condition each test helmet in accordance with any one of the following procedures:

     (i)   Ambient conditions. Expose to a temperature of 70° F and a relative humidity of 50% for 12 hours.

     (ii)   Low temperature. Expose to a temperature of 14° F for 12 hours.

     (iii)   High temperature. Expose to a temperature of 122° F for 12 hours.

     (iv)   Water immersion. Immerse in water at a temperature of 77° F for 12 hours.

 If during testing, the time out of the conditioning environment for a test helmet exceeds 5 minutes, return the helmet to the conditioning environment for a minimum of 3 minutes for each minute out of the conditioning environment or 12 hours, whichever is less, prior to resumption of testing.
