There is a newer version of the New York Consolidated Laws
2006 New York Code - Use Of Used And Unidentified Materials.
§ 27-588 Use of used and unidentified materials. The utilization of
used materials and unidentified or ungraded materials shall be limited
to non-structural elements, except:
(a) Such materials (or elements) may be reused, or continued in use,
at stress levels to which the materials or elements were subjected in
the previous construction, or at load capacity as demonstrated by load
test procedures as described in subdivision (a) of section 27-599 of
article three of this subchapter.
(b) Unidentified materials may be graded by the recovery and test of
representative samples, or by other means satisfactory to the
commissioner.
(c) Used materials shall be considered to be graded where the grade is
clearly indicated on the approved plans for the existing construction
and may be used at the allowable stress levels for that grade of like
material as established in the building code in force at the time the
plans for the existing construction were approved.

d Basic allowable stress values as referenced herein shall denote
allowable stress value without increase for infrequent stress conditions
as established in this code or in the applicable reference standard for
the material or element in its proposed use.

accepted as evidence of compliance with the provisions of this code for
all construction operations not subject to controlled inspection.
d Basic allowable stress values as referenced herein shall denote
allowable stress value without increase for infrequent stress conditions
as established in this code or in the applicable reference standard for
