Testing Application Process

Outline of MPI’s Testing and Listing Program.

The MPI Testing and Listing program is a third-party testing program that verifies and quantifies performance by testing products from all over the world to a single set of standards.

These standards, which encompass over 200 categories of products, utilize ASTM and in-house developed testing to ensure the products can perform in their respective uses. Products that pass this testing are listed on the MPI Approved Products List (APL)

Products that are listed are called for confirmation testing on a two-year schedule, determined by the standard category.

Confirmation testing costs less than initial testing and is used to ensure products continue

To become a listing manufacturer with MPI:

complete the following forms and send them to MPI’s Technical Specialist, Terrance Mayes

Testing and Listing Agreement

MPI015 – Manufacturer Contact Form

The documents are a Testing and Listing Agreement, that covers the structure and format of the testing process, and a Manufacturer Contact Form, that informs us who to send updates regarding invoicing or testing.
MPI will review the documents and provide credentials to access our Customer Portal.

The Customer portal is where you submit applications for testing, review current applications, and access reports for completed

For next steps, consults our guides below:

How Do I Submit an Application in the Customer Portal?

  1. Log in to the Customer Portal
    1. Go to and log in using your account
  2. On the menu bar, select Submit Application
  3. Enter the MPI category number desired and hit the search button
    1. In the case of X-Green and Recycled paints, a search for the base category number will show the sub-groups
  4. Click to select the desired category from the list that pops up and click select
  5. Select the type of application
    1. If this is the first time the product is being testing, or it is not currently listed, select “Initial”
    2. If this is an application for a currently listed product that has come due for testing, select “Confirmation”
    3. If you want to have a product tested for a specific property for review, select Batch Conformance
  6. Fill out the application
    1. Product label, name, and code are what will appear on the APL
    2. Upload a Safety Data Sheet (SDS) and Technical Data Sheet (TDS) in PDF format
      • Ensure the file names are 16 characters or less, to ensure they upload properly
    3. Paint label is not required, but can be used for identification
    4. Enter the product’s VOC amounts in g/L
  7. Answer the regulatory questions
    1. Information on MPI’s Green Performance Standard can be found here: [link to GPS]
    2. OTC is the Ozone Transport Commission which sets VOC guides for the northeast United States under the Clean Air Act
    3. EC is Environment Canada and refers to VOC limitations
    4. LEED is the Leadership in Energy and Environmental Design, which is a green building rating system
  8. Enter your initials to confirm that the information is correct to the best of your knowledge
  9. Select the regions in which the product is available for purchase
  10. If the product is for normal testing and should be listed after approval, leave the Do Not List as “No”
    1. If the product is to be tested for internal review, and should not be listed, select “Yes”
  11. Click submit
  12. Make note of the PS# and if the product needs a sample sent in for testing
    1. Intended Use and X-Green do not require samples
    2. Detailed Performance and Evaluated Performance require samples
  13. Prepare a 1-gallon sample of the product to send to the lab for testing
  14. Write or otherwise affix the PS# on the product can for identification at the lab.
    1. If the product is being tested for multiple categories, the PS#’s from each of those separate applications can be put on one can.
  15. Send the sample to the lab for testing.
    1. All shipping costs and documentation, including customs, are the responsibility of the manufacturer.

What are the Benefits of MPI’s Approved Products List and Testing Program?

For manufacturers, MPI’s testing ensures a level playing field by testing all products in a category to the same requirements. Manufacturers can point to the MPI Approval as a trusted third-party performance-based assessment of their products.  The APL also works to get information about a manufacturer’s products out into the public through the categorical listings, as well as MPI’s monthly newsletter detailing new products.

For specifiers, asset owners, and contractors, MPI’s Approved Product List provides peace of mind that any listed product has met the rigorous requirements of MPI’s standards. The Approved Products List also provides a simplified and flexible way to specify a coating type for use in projects and is made easier by the APL’s inclusion in the American Institute of Architect’s Masterspec as well as MPI’s own Decision Tree utility. 

How Are Costs Calculated?

At MPI, costs for testing and listing products can be divided into two categories: Testing Fees and Listing Fees.
Testing Fees are charged for evaluating a product against the relevant MPI standard, and will vary based on the specific standard, as well as whether the product is being tested for the first time (Initial) or is undergoing a renewal test (Confirmation). In most cases, Confirmation testing is less expensive than Initial testing, with the exception of X-Green and Intended Use products, which have the same fees for both Initial and Confirmation testing.

Listing Fees are charged to maintain a product's listing in the Approved Products List. This fee has two components: the Annual Listing Fee and the Additional Listing Fee. The Annual Listing Fee is a yearly fee required for any manufacturer wanting to list a product with MPI. It covers one listing per category (although the product must still be tested and is subject to the Testing Fees outlined above). The Additional Listing Fee is for manufacturers who wish to have multiple listings within a category. It can be added multiple times, and each instance allows for an additional potential listing in every category.

For example, if a manufacturer has one product in each of ten categories, and four products in MPI 10 and two products in MPI 15, they would be charged the Annual Listing Fee and three instances of the Additional Listing Fee (four listings minus one covered by the Annual Listing Fee). They would not be charged a fourth Additional Listing Fee for the two products in MPI 15 since those fees are already included in the fees assessed for the four listings in MPI 10.

How Long does Testing Take?

The time it takes for a product to be tested and approved varies widely based on several factors. Besides shipping delays and being damaged in transit, the biggest variable is the category or categories being tested.

Some categories have extensive tests that can take months to complete. These include the accelerated weathering tests for exterior products, corrosion resistance for anti-rust or other select metal coatings, and biological testing, also for most exterior topcoats (and which is performed following the accelerated weathering, increasing the time frame). These tests are designed to ensure the coating performs properly, and currently there is no way to materially shorten the time required.

Other categories, especially some interior coatings, have relatively shorter testing time frames and can be completed in as little as two weeks from receipt of the sample, but usually one to two months is normal.

Following testing, the results are subjected to a Quality Control review at the lab, which can take up to a week to complete if there are concerns.

Finally, results are reviewed by MPI and the product either passes or fails. In either event, a report will be available in the Customer Portal for viewing and download. The status of all applications can also be reviewed in the portal.

Statuses are as follows:

Unresolved: Application received, but sample not received yet

Received: Sample has arrived at the lab

Updated: Awaiting either QC or MPI review

Waiting:  Needs further action from the manufacturer; may have failed testing

Published: Passed testing. Report is available and product will be listed in the APL the following month
