Standard Test Method for Resistance to Environmental Degradation of Electrical Pressure Connections Involving Aluminum and Intended for Residential Applications
 N B812

Annotation

This test method covers all residential pressure connection systems. Detailed examples of application to specific types of connection systems, set-screw neutral bus connectors and twist-on wire-splicing connectors, are provided in Appendix X1 and Appendix X2.

The purpose of this test method is to evaluate the performance of residential electrical pressure connection systems under conditions of cyclic temperature change (within rating) and high humidity.

The limitations of the test method are as follows:

This test method shall not be considered to confirm a specific lifetime in application environments.

The applicability of this test method is limited to pressure connection systems rated at or below 600 V d-c or a-c RMS.

This test method is limited to temperature and water vapor exposure in addition to electrical current as required to measure connection resistance.

This test method does not evaluate degradation which may occur in residential applications due to exposure of the electrical connection system to additional environmental constituents such as (but not limited to) the following examples:

Household chemicals (liquid or gaseous) such as ammonia, bleach, or other cleaning agents.

Chemicals as may occur due to normal hobby or professional activities such as photography, painting, sculpture, or similar activities.
