B. PAINT ALL EXPOSED SURFACES, INCLUDING THE INSIDE SURFACES OF THE CONTAINER EXCEPT AS FOLLOWS. DO N OT PAINT FASTENERS, THREADED PORTIONS OF HOLES, OR THE GASKET.

C. ABRASIVE BLAST SURFACES TO NEAR WHITE METAL PRIO R TO PAINTING. IF ABRASIVE BLASTING IS NOT APPROPR IATE, OTHER MECHANICAL MEANS SUCH AS CHIPPING OR

SANDING MAY BE USED.

D. PAINT STEEL SURFACES WITH TWO COATS OF AMERCOAT 235 PAINT CONFORMING TO MIL-PRF-23236. THE FIRST COAT SHALL BE A COLOR OTHER THAN BLACK AND APPLIED TO A DRY FILM THICKNESS (DFT) OF 4 MILS. THE TOP C OAT SHALL BE BLACK APPLIED TO A DFT OF 4 MILS (MIN) .

6. CLEANLINESS REQUIREMENTS: BEFORE AND AFTER PAINT ING, ENSURE ALL ACCESSIBLE SURFACES ARE VISIBLY FRE E OF CUTTING FLUID, TAPE RESIDUE, MACHINE CHIPS, GREASE, OIL, FLUX, DIRT, GRIT, SCALE, RUST, SMEARED METAL, WELD SPATTER, OR OTHER FOREIGN MATERIAL.

9. SAFETY HOIST RING LOAD TEST REQUIREMENTS:

THE 1/2-13 UNC-2B SAFETY HOIST RING LIFT HOLE (IN T HE TOP, PC 4) IS PROVIDED FOR LIFTING AND HANDLING. PROOF TEST VALUES ARE FOR A WORKING LOAD LIMIT (W LL) OF

2,500 LBS.

TORQUE-BASED PROOF TEST OF SAFETY HOIST RING HOLES:

A. OBTAIN A SOCKET HEAD CAP SCREW (UNC-2A OR UNC-3A , ASTM A574 OR ASME B18.3, 1/2"-13 UNC, MINIMUM 2.0 0" SHANK LENGTH (EXCLUDING HEAD) FULLY THREADED, HE AVY HEX NUT (ASTM A194/A194M GRADE 2H, UNC-2B, 1/2"-13) AND A HARDENED WASHER (TO FIT THE 1/2"-13 CAP SCRE W, ASTM F436, TYPE 1, CIRCULAR).

B. THREAD THE NUT ONTO THE CAP SCREW UNTIL THE LEAD ING SURFACE OF THE NUT IS AT THE REQUIRED LENGTH OF THREAD ENGAGEMENT (0.78 +0.00/-0.04 INCHES FOR THE 1/2"-13 CAP SCREW). THE TOLERANCE ON THREAD ENGAGE MENT IS +5/-0% WITH A MINIMUM TOLERANCE OF 1/32 INC H (SEE FIGURE 1).

C. APPLY MOLYKOTE P37 (OR EQUIVALENT) LUBRICANT TO THE THREADS ABOVE AND STARTING AT THE LEADING SURFA CE OF THE NUT (SEE FIGURE 1). THREAD THE NUT FULLY ONTO THE LUBRICATED THREADS OF THE CAP SCREW AND AP PLY LUBRICANT TO THE TRAILING SURFACE OF THE NUT. DO NOT LUBRICATE THE LOWER CAP SCREW THREADS. IN THIS ARRANGEMENT, ONLY THE PORTION OF THE THREADS O N THE CAP SCREW THAT ENGAGE THE NUT ARE LUBRICATED. THE CAP SCREW THREADS THAT ENGAGE THE TAPPED

HOLE OF THE COMPONENT ARE NOT LUBRICATED.

D. INSPECT THE LIFT HOLE THREADS FOR LUBRICATION, D IRT AND DEBRIS. CLEAN AS NECESSARY (REMOVING ALL L UBRICATION, DIRT, AND DEBRIS). INSTALL THE PROOF T EST ASSEMBLY (CAP SCREW, NUT AND WASHER) INTO THE TAPPE D HOLE TO THE REQUIRED DEPTH OF THREAD ENGAGEMENT OF 0.78 +0.00/-0.04 INCHES FOR THE 1/2"-13 CAP SCREW

(SEE FIGURE 1).

E. WHILE RESTRAINING THE CAP SCREW, TORQUE THE NUT TO 28 +1/-0 FT-LBS (THE TOLERANCE IS +5/-0%). RE-C HECK THE TORQUE ON THE NUT.

F. AFTER TEN MINUTES, REMOVE THE PROOF TEST ASSEMBL Y. REMOVE ANY TRANSFERRED LUBRICANT (1X VISUAL CON FIRMATION OF REMOVAL REQUIRED) FROM THE TAPPED

HOLE AND SURROUNDING SURFACES AT THE COMPLETION OF PROOF TESTING.

G. PRIOR TO AND AFTER PROOF TEST, VISUALLY (1X) INS PECT THE TOP (PC 4) FOR SIGNS OF DEFORMATION, CRACK S, OR DAMAGE THAT MAY AFFECT THE LIFTING CAPACITY O F

THE THREADED HOLE.

H. PERFORM A 2B "GO/NO-GO" GAGE CHECK OF THE THREAD ED HOIST RING HOLE IN THE TOP (PC 4). THE "GO" GAG E ACCEPTANCE CRITERIA IS THAT THE GO GAGE CAN BE FU LLY INSERTED INTO THE THREADED HOLE. THE "NO-GO" GAGE ACCEPTANCE CRITERIA IS THAT THE NO-GO GAGE DOES NOT ENTER THE THREADED HOLE MORE THAN THREE

COMPLETE TURNS.

I. PRIOR TO AND AFTER PROOF TEST, PERFORM A MAGNETI C PARTICLE TEST (MT) INSPECTION PER REFERENCE C OF THE SPECIFIED PORTION OF THE TOP PLATE (PC 4) SHOWN ON SHEET 8. USE THE ACCEPTANCE CRITERIA OF REFERENCE D CLASS 3 FOR WELDS AND FORGING/WROUGHT MATERIAL FOR BASE MATERIAL.

J. PROVIDE WRITTEN DOCUMENTATION THAT THE ABOVE PRO OF TEST AND NDT REQUIREMENTS WERE SATISFACTORILY PE RFORMED.

K. FOLLOWING SATISFACTORY COMPLETION OF PROOF TEST, PERMANENTLY MARK LOAD TEST INFORMATION IN THE AREA INDICATED ON SHEET 8. ENSURE THAT THE MARKING WILL NOT INTERFERE WITH SAFETY HOIST RING INSTALLAT ION. MARK THE HOLE WITH THE FOLLOWING:

"FOR LIFTING OF LID ONLY

SPS CAPACTIY: 300 LBS.

LOAD TEST/ NDT DUE DATE: N/A, SF 10

LID NUMBER 'XX'"

WHERE 'XX' IS THE UNIQUE SERIAL NUMBER MATCHING THE LID TO THE SPECIFIC CONTAINER.

10. LIFTING LUG LOAD TESTING REQUIREMENTS:

THE TWO LIFTING LUGS (PC 5) THAT ARE WELDED TO THE SIDES OF THE CONTAINER ARE TO BE LOAD TESTED USING A VERTICAL TENSION LOAD. THE LOAD TEST VALUES ARE F OR A

WORKING LOAD LIMIT (WLL) OF 2,400 LBS. EACH.

A. PRIOR TO AND AFTER PERFORMING THE LOAD TEST, PE RFORM A VT (VISUAL TEST) INSPECTION OF THE ATTACHME NT WELDS OF EACH LIFT LUG (PC 5), THE ACCESSIBLE BA SE METAL OF EACH LIFT LUG (PC 5), THE SURROUNDING BASE METAL OF THE CONTAINER WALL (PC 2), THE WELDS ATTA CHING THE WALLS (PC 2), THE WELDS ATTACHING THE WAL LS (PC 2) TO THE BASE (PC 1), AND THE EXTERIOR WELDS A TTACHING THE WALLS (PC 2) TO THE FLANGE (PC 3). ENS URE THERE IS NO APPARENT DEFORMATION, CRACKS, OR OT HER

APPARENT DAMAGE OF THESE LOAD BEARING PARTS.

B. PRIOR TO AND AFTER THE LOAD TEST, PERFORM A MT ( MAGNETIC PARTICLE) TEST INSPECTION OF THE ATTACHMEN T WELDS OF EACH LIFT LUG (PC 5), THE ACCESSIBLE BAS E METAL OF EACH LIFT LUG (PC 5), THE WELDS ATTACHING THE WALLS (PC 2 TO PC 2), THE WELDS ATTACHING THE W ALLS (PC 2) TO THE BASE (PC 1), THE EXTERIOR WELDS ATTACHING THE WALLS (PC 2) TO FLANGE (PC 3) PER REF ERENCE C. USE THE ACCEPTANCE CRITERIA OF REFERENCE D, CLASS 3 FOR WELDS AND FORGINGS/WROUGHT MATERIAL

FOR BASE METAL.

C. PROOF LOAD TEST THE LIFT LUGS (PC 5) AS FOLLOWS: RESTRAIN THE SBDC OR USE TEST WEIGHTS AS NECESSARY TO TEST BOTH PADEYES SIMULTANEOUSLY TO 7,775 LBS (150% LOAD TEST) UP TO 8,164 LBS (155% LOAD TEST). THE LOAD TEST PLAN IS SHOWN IN FIGURE 2 (SHEET 10) . HOLD THE TEST LOAD FOR A MINIMUM OF 10 MINUTES.

D. FOLLOWING SATISFACTORY COMPLETION OF THE LOAD TE ST, DOCUMENT AND PROVIDE WRITTEN CERTIFICATION OF L OAD TESTING, VT INSPECTION TESTS, AND MT INSPECTION TESTS (INCLUDE THE TEST DATES). ENSURE DOCUMENTATIO N CLEARLY SPECIFIES PERFOMANCE OF "PRE" AND "POST" LOAD TESTING INSPECTIONS, INSPECTION METHODS USED, ACCEPTANCE CRITERIA USED, AND ITEMS (PIECES, AREAS, AND WELDS) THAT WERE INSPECTED.

E. CONTRACTOR(S) PERFORMING NDT PROCEDURES IN ACCORDANCE WITH NAVSEA PUBLICATION T9074-AS-GIB-010/271 (REFERENCE C) ARE REQUIRED TO DEVELOP AND MAINTAIN A WRITTEN PROC EDURE THAT HAS BEEN QUALIFIED TO MEET THE REQUIREME NTS OF NAVSEA PUBLICATION T9074-AS-GIB-010/271. A COPY OF THE QUALIFIED PROCEDURE SHALL BE INCLUDED WITH THE NDT

DOCUMENTATION REQUIRED BY THIS DRAWING (FOR ENGINEE RING REVIEW).

F. FOLLOWING SATISFACTORY COMPLETION OF LOAD TESTIN G, PERMANENTLY MARK ADJACENT TO EACH OF THE LIFT LU GS (PC 5) AS

SHOWN ON SHEET 5. MARK THE CONTAINERS WITH THE FOLL OWING:

"SPS CAPACITY: 2,400 LBS

LOAD TEST/NDT DUE DATE: N/A SF 10

UNLOADED WEIGHT = X,XXX LBS (RECORDED IN NOTE 8)

MAX LOADED WEIGHT = 4,000 LBS.

MIN SLING LENGTH 2 FT.

CONTAINER NUMBER XX"

WHERE XX IS THE UNIQUE SERIAL NUMBER OF THE CONTAIN ER MATCHING THE LID AND LOAD TEST CERTIFICATION PAP ERWORK.
