Universal Paints Requirement Document• Completed update to FY-13 Standard Item 009-32 and submitted for final review:

- Continued adding submarine- and carrier-specific items.- Changes in personnel.

Accomplishments:

1. Update to receipt inspection language allowing conformance test and or receipt inspection.2. Added single-coat option for Bilges and Well decks and added language for "Enclosed Boat

Handling Areas."3. Removed the 5 mil upper limit for individual profile readings. "For Method B or C of 2.9, the

average of profile readings shall be between 2 and 4 mils, with no individual reading less than one mil.“ Also, no longer require nonskid surface profile readings to vary by <0.5 mils.

4. No longer need to record environmental readings during surface preparation of nonskid areas.5. Reworded pre-construction primer paragraphs to allow thorough pressure washing as an

alternative to SP-7. 6. Coating DFTs in excess of 50 mils will be assessed by the local engineering code to ensure

higher coating thickness is not a problem. “Sanding shall not be performed for high coating thickness areas without SUPERVISOR approval .”

7. Clarified that if waiving stripe coat, the additional DFT readings are performed on the final topcoat.

8. Added new Table/Line for powder coating of Watertight Doors.9. Polysiloxanes for exterior application on aluminum surfaces were previously listed as only one

full coat. Fixed this item to require either epoxy or polysiloxane stripe and polysiloxane topcoat.10. We previously added allowance for permanent markers to mark holidays. New change states that

permanent markers are not allowed in SEA08 areas.

Update to Standard Item 009-32 in process key issue is sanding and potable water

6

Conductivity/Chloride Measurement Device Letter Signed

• Completed letter addressing conductivity/chloride measurement policy, Ser. 05P/322,dated 8 MAR 2012 that defines chloride measurement device use and approval policy.

• Letter rescinds 1998 approval letter that allowed use of Elcometer 130 / SCM400.Acknowledges successful use for last 13 years and allows activities to produce required OQE to validate that this device performance vs. Bresle/Horiba method.

• Fully defines “A-1250 Bresle”/”Horiba B-173” method. Uses sketches from early standard item and defines process as baseline.

• Allows use of any device - provided a shipyard obtains OQE that a given device or process performs equivalently to established processes:

1. Approved in current Standard Item 009-32.2. Satisfies NACE Standard Practice SP0508-2010, Methods of Validating

Equivalence to ISO 8502-9 on Measurement of the Levels of Soluble Salts3. Consistent performance to Bresle/Horiba conductivity method.4. Consistent with Bresle/chloride measurement. This section

prohibits inferred or calculated chloride measurement.

Shipyards don’t need to get NAVSEA approval for contamination measurement systems

7

QA/QC “Minimum” Guidance DRAFT Letter in Process

• Completed draft letter addressing minimum levels of actions.

• Letter addresses three key technical goals for QA oversight:1. Inspection of paint process requires on-site work – see, touch, smell, etc.2. (G) point is about reviewing contractor data, not taking data.3. (G) point validation ideally is a “one-step process” - if “good” only one reading required

– no limit on additional data collection for non-compliant work.

• Goal is one-step review, one (G) point signature for entire package - paperless QA.

• QUALIFICATIONS FOR CONDUCTING QA OVERSIGHT (Standard Item 009-32, paragraph 3.9.1). NAVSEA technically authorizes QA oversight by credentialed personnel from:

- Naval shipyard quality assurance or engineering departments.- Regional Maintenance Center quality assurance, ship building specialist, or engineering

departments.- Trident Refit Facility quality assurance, ship building specialist, or engineering

departments.- Supervisor of shipbuilding quality assurance, ship building specialist, or

engineering departments.- Naval Warfare Centers and/or Naval Research Laboratory staff tasked to

conduct oversight.- Contractors or other non-governmental personnel. Must not be funded by prime or

subcontractor but rather must represent government interest.

Streamlining QA processes and procedures benefit shipyards and government.

8

QA/QC “Minimum” Guidance DRAFT Letter

• COATING INSPECTION FOR EACH PAINT COAT (Paragraph 3.10.10):- (G) point for each coat.- Verify specified coating and color for work area or zone on the DLA’s

qualified products database (https://assist.daps.dla.mil/quicksearch).- Applied as per requirements (validate environmentals, wind, etc.)

or ASTM F-718.- Coatings are not contaminated with grit, steel shot, dirt, or foreign matter. - Visual coverage of the coating on all surfaces, inspected using an LED light

without magnification and at a distance of approximately three to five feet.- Coating dry film thickness is consistent with requirements. - “For the given work zone or area that is to be addressed by the (G) checkpoint,

the inspector shall take one set of three dry film thickness gauge readingswithin a 1.5-inch (i.e., 4 centimeter) diameter circle or shall observe contractor/trades personnel taking one set of three readings within the spot.”

- NAVSEA does not technically require inspectors to be on-site for all DFTreadings or contractor/trade visual inspections.

- NAVSEA estimates based on NSRP July 2011 “The Cost of US Navy CoatingsQA/QC,” Table 3 shows for a representative 1,000 ft2 work area or zone, 75% of respondents with NBPI credential could complete inspection in:< 5-hours with only 30-minutes added for each additional 1,000 ft2

Does time per (G) checkpoint estimate correlate with NSRP Cost of QA Assessment?

New Construction Paint Working Group• SEA 05P2, 25 JAN 2012 letter already authorized use of Standard Item 009-32 as basis for cost

reduction candidates.

• SEA 05, 8 FEB 2012 Working Group for new construction cost reduction plan is for NAVSEANAVSEA to supply “turn key” concepts for cost reduction to shipbuilder.

• Shipbuilders take ideas and return ideas that will streamline operations, to Program Offices as actionable, contractual modification.

Letter from SEA 05 to Shipyards April 2012, Ser 05D/108 to 152

1. Notes interest in achieving a single process that is lower cost compared to current requirements.

2. Notes goal of bilateral talks to achieve implementation.

Launch: If blocking areas do not match surrounding color (e.g., black vs. red) record condition to allowdivers to anticipate the inconsistent color during future inspections. If colors match, no action is required.OQE: As per established contract.

18

Reduce Surface Preparation on Tie Downs

IDEA: Do not require SSPC SP-10 on deck tie downs and allow SSPC SP-3 hand tool preparation.

RISK: Negligible, because coatings are damaged from normal use by ship’s force. Standard Item 009-32 already allows relaxed surface preparation.

REFERENCE: FY-12, Change 1, NAVSEA Standard Item 009-32, FY-12, paragraph 3.11.3.1

Technical Requirements to Not Require SSPC SP-10 on Tie DownsMaterial: MIL-PRF-24667 non-skid or as approved by contract.

OQE: As per established contract.

Surface preparation: SSPC SP-10 with sharp, angular media. Surface profile 2-4 mils with no single readingin excess of 5 mils or below 1 mil on accessible surfaces like the tops of the cross bars and deck area around the tie-down.

Inaccessible areas shall be prepared using either power-tool cleaning to SSPC SP-3 or hand-tool cleaning to SSPC SP-2.

OQE: As per established contract. As per SSPC SP-2, paragraph 2.2, SUPSHIP shall validate that all loose rust, mill scale, or paint has been removed using a dull putty knife.

Application: Paint shall be applied in accordance with established practices at established dry film thicknesses (DFTs).OQE: As per existing contract.

damaged coating that is allowing tie-down corrosion.

19

Use Galvanized Fasteners Instead of Painted Steel

IDEA: Use galvanized steel instead of painted steel inside the ship.

RISK: Negligible risk of corrosion, practice superior to paint over carbon steel.

REFERENCE: None, standard practice.

Technical Requirements to Use Galvanized FastenersMaterial: Mild, carbon-steel fasteners (i.e., strength lower than or equal to SAE J429 Grade 5)

that are sized and procured with a galvanized coating.

Galvanized coatings shall be ASTM-A-123 or ASTM-A-153 that call out use of an ASTM-B-6 zinc bath.ASTM-B-6, “Prime Western Grade Zinc” could have Pb content of between 0.5% to 1.4 % NAVSEA concurs with accepting the Pb levels in the Prime Western Grade Zinc,or any other galvanizing bath grade with lower levels of Pb, because the fasteners oninterior ducts on the ship are considered life-of-the-ship parts that will not be abrasiveblasted, welded, or otherwise disturbed throughout the life cycle in a manner thatwould create airborne dust/fume.

OQE: As per established contract. Shipbuilder and SUPSHIP shall concur on galvanized partprocurement specifications.

Surface preparation: Galvanized surfaces covered by lagging require no surface preparation orcoating. Surfaces to be painted shall be cleaned to SSPC SP-2.

OQE: As per established contract.

Application: Galvanized surfaces covered by lagging require no surface preparation or coating. Surfaces to be painted shall be painted using the same system as the surrounding duct.

OQE: As per established contract.
