5、Resistance TestRATIONALEARP6404 has been reaffirmed to comply with the SAE five-year review policy.1. SCOPEThis document points to a standard ASTM test method utilized by land vehicle manufacturers and others to provide the electrical resistance of a tire. It is desired that this ASTM test method is
6、 also used with aircraft tires. This method will assure that more accurate repeatable data is provided to those in the aerospace industry who request it. 1.1 Purpose The purpose of this ARP is to define a test procedure for determining the electrical resistance of an aircraft tire. 2. REFERENCESThe
7、following publications form a part of this document to the extent specified herein. The latest issue of SAE publications shall apply. The applicable issue of the other publications shall be the issue in effect on the date of the purchase order. In the event of conflict between the text of this docum
8、ent and references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 2.1 ASTM International Publications Available from ASTM International, 100 Barr Harbor Drive, P.O.
