This document specifies the following: a. general dimensions and capacities; b. performance requirements; c. balancing speed ranges; d. drive power requirements; e. balancing machine spindle flange dimensions; and f. test procedures.
Proving rotors and associated test masses required for the performance tests are described in ARP4162.
Test procedures are described in detail and test log samples along with a polar diagram for evaluating the test results are furnished.
The predecessor document ARP588, ISO 2953, and the available technology of hard-bearing balancing machines have been considered in the preparation of this document.
This document was developed for hard-bearing balancing machines but may also be used for existing soft-bearing balancing machines.
This SAE Aerospace Recommended Practice (ARP) is only applicable to 14 CFR part 25 Transport Airplane passenger seats. This document provides an approach for determining which parts on aircraft seats are required to meet the test requirements of 14 CFR part 25 Appendix F, Parts IV and V. Such materials are referred to as Heat Release Special Conditions (HRSC) compliant]. Additionally, it is recommended to use HRSC compliant materials in applications where not required.
Independent furniture related to seat installations is outside the scope of this document.
