ASTM B 812 Document Information:
Title
Standard Test Method for Resistance to Environmental Degradation of Electrical Pressure Connections Involving Aluminum and Intended for Residential Applications
ASTM International
Publication Date:
May 10, 1996
Scope:
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.
Environments encountered during construction or remodeling such
as direct exposure to rain, uncured wet concrete, welding or
soldering fluxes and other agents.
This test method is limited to evaluation of pressure connection
systems.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to become familiar with all hazards
including those identified in the appropriate Material Safety Data
Sheet (MSDS) for this product/material as provided by the
manufacturer, to establish appropriate safety and health practices,
and determine the applicability of regulatory limitations prior to
use.
This standard should be used to measure and describe the
properties of materials, products, or assemblies in response to
electrical current flow under controlled laboratory conditions and
should not be used to describe or appraise the fire hazard or fire
risk of materials, products, or assemblies under actual
installation conditions or under actual fire conditions. However,
results of this test may be used as elements of a fire risk
assessment which takes into account all of the factors which are
pertinent to an assessment of the fire hazard of a particular end
use.
