Third Party Inspection for UPS Storage Battery - Procedure

The Third Party Inspection for UPS Storage Battery is a sample procedure for UPS Storage Battery inspection and testing in manufacturing shop.

You may need to review this article along with the following article:

Inspection and Test Plan for UPS Storage Battery

This content guides you through all the necessary stages in the production of the UPS storage batteries, including the raw material, final inspection, preservation and packing, and dispatch to site.

You need to take this point into account: this article is written for a typical UPS storage battery and might not be detailed for special cases.

This content may be useful for second party inspectors, UPS storage battery manufacturer quality control personnel, engineering companies, and purchasers, as well.

All UPS storage battery inspection and testing is done against the approved drawings, purchase order specifications, purchasers or company standards, and within the practices and rules of the country, state or province and any government decrees, laws, ordinance or regulation as may apply.

The applicable codes and specifications for a UPS storage battery that is under the construction process is:

Design code
Purchase order specification
Purchaser's standards
Approved drawings

The applicable codes and standards may be based on any international standards. This content is general and can be useful for all recognized standards.

Required Documents for Third Party Inspector Review:

The list of documents normally is agreed upon in the Pre-Inspection meeting, which is held several weeks before the actual commencement of the inspection work. The parties that participate in this meeting are the manufacturer, purchaser and third party inspection agency representatives.

This is already explained in the Inspection and Test Plan for UPS Storage Battery article.

These are the list of documents that are normally agreed upon to be presented to the inspector:

UPS Storage Battery Purchase Order or Contract
UPS Storage Battery Manufacture Quality Control Plan
UPS Storage Battery Inspection and Test Plan
UPS Storage Battery Data Sheet
UPS Storage Battery Approved Drawings, (arrangements, schematics, wiring, single line)
UPS Storage Battery Material Test Reports
UPS Storage Battery Calibration Certificates for Test Equipment
UPS Storage Battery Special Procedures
UPS Storage Battery Special Qualifications
UPS Storage Battery Preservation, Packing and Shipping Procedure
UPS Storage Battery Packing List

Third Party Inspection for UPS Storage Battery - Material Inspection

The first actual inspection work in the cUPS storage battery is the raw materials inspection.

The original or authenticated copies of mill certificates of material normally are available at the manufacturer's premises.

The third party inspector examines these certificates for compliance with specifications, and where appropriate, drawings.

The review includes checks on:

Maker’s name and location
Certificate number, grade
Batch number
Chemical composition
Cast number (for metal parts)

Ancillary items may be supported by test certification, or by certificates of conformity. It is necessary the content of certification to be appropriate to the required scope of the items.

Then the inspector witnesses the materials identification on the certificates against the materials marking. It is also necessary to check these with the UPS storage battery drawing datasheet, material list and other specifications as appropriate.

Visual inspection for surface finish and probable defects is done and dimensional compliance with specification need to be controlled, as well.

When the third party inspector carries out the material inspection, then provides the inspection visit report (IVR), the report contains the following items:

Confirmation of satisfactory document review
Record of the endorsement of certification reviewed/witnessed
Record of all non-conformities
Record of any tests witnessed and the result

Third Party Inspection for UPS Storage Battery - Construction of Ancillaries

When the UPS storage battery raw material inspection is carried out, and the results were satisfactory or non-conformities were closed by remedial action, then the UPS storage battery manufacturer will start fabrication.

The third party inspector checks the following points on the UPS storage battery based on the inspection and test plan (ITP), which has already been agreed upon between the purchaser and the UPS storage battery manufacturer.

The inspection scope is determined in the ITP. Some purchasers prefer to have stringent controls and assign the TPI for more “hold or witness points” for inspection and test activities, and some others prefer less “hold or witness points” and assign the TPI much more work in the “review document.”

This depends in the inspection budget, which purchasers assign for inspection. Much more inspection will have a much larger cost and less risk, and conversely, less inspection will have less cost but more risks.

For more details, review the Inspection and Test Plan for UPS Storage Battery article. There is a draft of the ITP in this article, which we believe is the best practice for UPS storage battery inspection.

The third party inspector checks following in accordance of approved drawings and applicable standards

Paint using specified colour swatch, measure thickness, if specified
Name plate
Outline dimensions, interface dimensions

If the third party inspector is not in the hold or witness point in the ITP for this inspection stage, then he/she will review the UPS storage battery manufacturer quality control report in his/her coming visit or on the final inspection day.

Third Party Inspection for UPS Storage Battery - General Arrangement Check

The third party inspector checks that all parts are appropriate to correctly assemble to the battery layout with specified labelling.

The inspection is done based of approved drawings.

Similarly, If the third party inspector is not in the hold or witness point in the ITP for this inspection stage, then he/she will review the UPS storage battery manufacturer quality control report in his/her coming visit or on the final inspection day.

Third Party Inspection for UPS Storage Battery - Physical Checks

The third party inspector checks cells and ancillaries for type, quantity, construction material, rating, identification marking, freedom from damage, deformation or other or other visible defects and Dimension.

UPS Storage Battery would be pass inspection if meets the approved drawings and datasheets.

Third Party Inspection for UPS Storage Battery - Tests

Third party inspector witnesses capacity, leakage, voltage and absence of short circuits tests.

The UPS Storage Battery would pass the tests, if the tests results meet the acceptable limits specified in datasheets and purchase order specifications.

Third Party Inspection for UPS Storage Battery - Reporting:

The third party inspector provides an Inspection Visit Report (IVR) after each visit, as well as a final report summarizing the activities carried out during the UPS storage battery in accordance with the contract requirements and circulated within the time limits specified in the contract.

The report is in the format required by the client and clearly indicates final acceptance or rejection of the UPS storage battery.

Third Party Inspection for UPS Storage Battery - Release Note

When required by the contract or purchase order, a release note is issued by the third party inspection agency and given to the manufacturer when the UPS storage batteries have been accepted.

Third Party Inspection for UPS Storage Battery - Packing, Marking and Shipping:

The following points are checked by the third party inspector:

Verify that the packing materials conform to specifications and accepted practice for the mode of transport.
Verify protection against humidity, abrasion, distortion and other damage.
Verify shipping marks to marking instructions and record.
Verify handling marks.
