   CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED)
 
PART 54_PRESSURE VESSELS--Table of Contents
 
                      Subpart 54.05_Toughness Tests
 
Sec. 54.05-3  Tests required.

    (a) Where material or welding toughness tests are required by 
Sec. Sec. 54.25-10, 54.25-15, 54.25-20, and subpart 57.03 or 57.06 of 
this subchapter, the following requirements shall apply:
    (1) Additional requirements for ferritic steels with properties 
enhanced by heat treatment are in Sec. 54.25-20.
    (2) Certified reports of toughness tests by the material 
manufacturer will be acceptable evidence provided the specimens taken 
are representative of the material delivered and that the material is 
not subject to treatment during or following fabrication that will 
reduce its impact properties. If such treatment is subsequently applied 
to the material, test specimens shall be so taken and treated as to be 
representative of the material in the finished vessel.
    (b) The requirements of this subpart are also applicable to 
nonpressure vessel type low temperature tanks and associated secondary 
barriers, as defined in Sec. 38.05-4 of subchapter D (Tank Vessels) of 
this chapter.
