TESTING 

Certificate of Conformance (CoC) 

I. PURPOSE AND SCOPE The purpose of this Subsection is to prescribe procedures pertaining 

to verification of a contractor furnished CoC. These procedures are applicable to inspection 

personnel involved in DLA Troop Support contracts requiring inspection at origin or at 

destination in which the contractor is required to furnish a CoC as stipulated in the contract 

inspection clauses. 

II. RESPONSIBILITIES Origin QAR/inspector shall verify CoC in accordance with the 

procedures stated in DLA Troop Support contracts. The QAR shall review the CoC for 

completeness and accuracy and retain in a file. When specified in the contract, the contractor 

shall furnish a copy of the CoC covering each contract for each destination. The destination 

shall verify that the contractor has furnished the required CoC. 

III. VERIFICATION PROCEDURES

A. Verification of CoC by Examination The end item and any related labels, invoices, test 

results, etc, shall be visually examined to the extent possible to determine compliance 

with contract requirements. The review of the CoC for completeness and accuracy is 

not of itself adequate verification that the end item is conforming. The CoC, when 

verified by examination only, shall be annotated ‘Verified by Examination Only.’ 

B. Testing The end item shall be tested by a laboratory to determine compliance with 

contractual analytical requirements, when required. The CoC, when verified by 

testing, shall be annotated ‘Verified by Testing’ or ‘Verified by Examination and 

Testing’, as applicable. 

C. Verification Testing Frequency for Components Inspected at Origin under CoC 

Procedures. Unless otherwise specified in the contract or Quality Assurance Letter of 

Instruction (QALI), verification testing of components is required as follows: 

1. For operational rations, frequency of verification testing of the components 

which are under CoC procedure shall be as specified in Subsection 207.3 (one 

in six lots for a reliable CoC status). If more than 12 months are required to 

receive the six lots, one lot in each 12-month period shall be sampled for 

testing. 

2. The initial lot and one of each ten lots/shipments of component received from 

the same component supplier by a contractor for items not intended for 

operational rations shall be sampled for testing. If more than 12 months are 

required to receive the ten lots, one lot in each 12-month period shall be 

sampled for testing. 

3. Exception to the above is if conformance is contract requirements can be 

assured by visual examination, in which case, no sampling for testing is 

required. 

4. Verification testing frequency may be varied by DLA Troop Support-FTR, 

when appropriate, based on quality history. QARs are responsible for 

submitting additional samples whenever reason exists to question the validity 

of the CoC. The extent to which the QAR submits additional samples may 

depend on the necessity for economy in inspection, consistent with adequate 

quality assurance and dollar value of the supplies. Normally, component lots 

costing less than $1,000.00, except when intended for rations shall not be 
subject to verification testing. 

5. Components for which there are no analytical or physical test requirements 

specified need not be submitted for testing. For items acquired under the 

Commercial Item Description (CID), or Code of Federal Regulations (CFR), 

refer to Subsection 207.3. 

D. Standby Samples. Subsection 207.1 contains instructions for standby samples. The 

QAR shall select and retain standby samples for 30 days unless requested by personnel 

of DLA Troop Support-FTR to submit them for testing. The standby samples may be 

disposed of after 30 days. 

E. Submittal of Samples For Verification Testing. The QAR shall complete Section A of 

DD Form 1222 (Request for and Results of Tests) and forward with the sample to the 

designated laboratory (see Subsection 207.1).

F. Distribution of Verification Test Results. Distribution of verification of test results 

shall be in accordance with Subsection 

G. Unreliable Certification of Conformance. 

1. The Quality Assurance Specialist DLA Troop Support-FTR,, shall incorporate 

test results in the Quality History Records; evaluate results for significant 

differences from requirements, and notify the Administrative Contracting 

Officer (ACO)/Contracting Officer and QAR when the difference is sufficient 

to render the supplier’s CoC unreliable. 

2. The ACO/Contracting Officer will notify the contractor (information copy to 

DLA Troop Support ATTN: DLA Troop Support-FTR of the unreliable CoC 

status and inform the contractor that the rate of verification is being increased to lot-by-lot and that acceptance will be based 

on Government test results. In addition, the ACO/Contracting Officer will 

inform the contractor that he/she shall be charged for the costs incurred for 

Government testing until reliability has been reestablished. Once the 

contractor has been notified of CoC unreliability and until reliability is 

reestablished, the CoC will be accompanied by a copy of all actual contractor 

test results for all production lots in the shipment. 

3. The Quality Assurance Specialist DLA Troop Support -FTR, shall notify the 

ACO/Contracting Officer and QAR of the contractor’s eligibility for return to 

a reliable status. 

4. The ACO/Contracting Officer will notify the contractor (information copy to 

DLA Troop Support, ATTN: DLA Troop Support-FTR of the return of the 

CoC to a reliable status. 

5. The cost of testing by the Government during the period that the contractor’s 

results are unreliable shall be reported to the ACO/Contracting Officer by 

DLA Troop Support-FTR. The cost of sampling for testing during the period 

of unreliability of the CoC shall be reported by the Military QAR to DLA 

Troop Support-FTR for forwarding to the Contracting Officer. Costs assessed 

shall include those related to travel costs of inspector; cost of mailing samples; 

administrative time, and inspection, if applicable. Personnel costs shall be 

levied considering time spent by pay grade.
