4.1.1 Special consideration and acceptance of a material application may constitute generic
acceptance or set a precedent for repeated design cases where a Client uses the same
material types and/or grades for the same design purpose under the same service
conditions.
4.1.2 This generic acceptance is dependent on the Client demonstrating that the material
application of the products or product range is substantially identical to that case
initially considered. Further guidance on applying for a generic acceptance by a
Client for their specific material application may be obtained from the Client’s
local LR office.
4.1.3 The materials, manufacturing and fabrication techniques, and applications accepted
via Special Consideration processes may become more widely utilised. Following
successful performance and in-service feedback that the material application has
become a common practice within industry, this will eventually be reflected in
revisions to standards, statutory regulations and the Rules where applicable, based
on the evidence provided by the industry from such wider applications.
