Accurate measurement of ground reaction forces (GRF) are an essential prerequisite to understanding the nature and locomotion response mechanisms of complex slip and fall situations. Significant shortcomings have been reported with many devices currently used to measure static and dynamic frictional loads. This paper describes performance characteristics of the multicomponent quartz piezoelectric force plate (FP) which has been used successfully over two decades for various biomechanical measurements including materials and impact testing, shoe/surface study, and frictional and GRF testing.

The Subscriber will be responsible for all access control and security measures necessary to ensure that the Subscriber's IP addresses are not used to access the journals other than by authorized Users.
ASTM International grants to the Subscriber and Authorized Users at the Subscriber's Authorized Site, online access to ASTM's journal for which the Subscriber maintains a current subscription to the print or online version. This grant extends only to the Subscriber and such Authorized Users individually and may not be transferred to, or extended to, others.

Verification: ASTM has the right to verify compliance with this License Agreement, at its expense, and at any time during the course of normal business hours. To do so, ASTM will engage an independent consultant, subject to a confidentiality agreement, to review your use of ASTM Documents. You agree to permit access to your information and computer systems for this purpose. Verification will take place upon no less than 15 days notice, during normal business hours and in a manner that does not interfere unreasonably with your operations.

You are solely responsible for maintaining the confidentiality of your password and for ensuring the authorized access and use of The ASTM Document.
Definitions. For purposes of this License, an Authorized Site is a localized site (one geographical location) that is under a single administration at a single location. For a Subscriber with locations in more than one city, each city is considered to be a different site. For a Subscriber with multiple locations in the same city, each location is considered to be a different site. (If you are seeking online access for multiple sites, please contact Kathe Hooper, ASTM International, at email@example.com or phone: 610-832-9634). Authorized User means only the employees, faculty, staff, and students officially affiliated with the Subscriber at the Authorized Site, and persons with legal access to the library's collections and facilities at the Authorized Site, using an IP address within the range identified in the subscription. Authorized Users may be persons remote from the Subscriber's physical location whose access is administered from the Authorized Site, but not persons at remote sites or campuses with separate administrations. For example, an employee of the Subscriber may be considered to be an Authorized User when accessing the Subscriber's network from home or while traveling to another city; however, employees of a branch campus or facility in another city are not considered to be Authorized Users. Subscriber is the person or entity which has subscribed to the ASTM journal and agreed to the terms of this limited license.
