Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability c7249 performance standards.

Core materials applicable include continuous foams and discontinuous bonding surfaces honeycomb. The fixture and specimen are aligned — specimen perpendicular to the loading bars with the bars perpendicular to the plane of the specimen facing.

Facing properties of sandwich constructions by long beam flexure, so called four point flexure.

Four point flexure of flat sandwich constructions to produce curvature of the sandwich facing plane. Within the text the inch-pound units are shown in brackets. Auditing Consulting Sourcing Training. It is ast responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Initiate e7249 compressive force until failure. Link to Active This link will always route to the current Active version of the standard.

Tests to evaluate core shear strength may also be used to evaluate core-to-facesheet bonds. Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb.

Permissible core material forms include those with continuous bonding surfaces such as balsa wood and foams as well as those with discontinuous bonding surfaces such as honeycomb. Combining values from the two systems may result in non-conformance with the standard. Standards may be obtained from appropriate standard authorities. This standard does not purport to address all of the safety concerns, if any, associated with its use.
