About the Program

SWR Institute is proud of its Validation Programs.  Begun over 10 years ago with liquid sealants, we have expanded to include many other products used on a daily basis in our industry.  The Product Validation Program is designed to validate certain performance data that is found on manufacturer's MSDS statements.  All of our validation programs are voluntary and laboratory tests are conducted by approved independent laboratories.  This approach assures the user of validated products that they match or exceed the various tested performance criteria.  The Validation Seal granted to successfully validated products has a specific time frame which upon expiration, the manufacturer has to re-submit the product for new testing.  Additionally, if there is a change in formulation, the manufacturer has to submit for new validation.  The SWR Institute's Product Validation Program is another tool that end-users, specifiers, designers and engineers can use to ensure the effectiveness of products they want to use.

Product Validation Program Details

The Liquid Sealant Validation Program was established to validate the published test results of the various sealant products on the market. The intent of the program is to provide specifiers and end-users of sealant products an unbiased method to judge whether sealant products will perform at the levels of the manufacturer's published data sheet for that particular product.

Performance Properties Profile

Validation of the SWR Institute Performance Properties Profile shall include the following ASTM tests:

  • C 719 (Canada - Method 14.4 - Can 2-19.0-M77) Adhesion and Cohesion of Elastomeric Joint Sealants Under Cyclic Movement (Hockman Cycle). Test must be performed to validate the greatest joint movement capability claimed on the Manufacturer's data sheet.

**** As of September 2012, ASTM C 661 is no longer required under SWR Institute's Sealant Validation Program.

Please note: All ASTM tests performed shall be the latest or current edition. All tests performed shall NOT be modified in any way. Sealant color for testing shall be selected from manufacturer's standard color chart.

Validation shall remain in effect for five years from the date of the validation testing. In the event the sealant product is re-formulated by the manufacturer, the product must be re-tested and re-validated. Upon expiration of the validated product, it must be re-submitted for testing even if no changes have been made to the product.

Product Validation FAQs

How long will I have to wait to get Validation data?
I require independent test data from manufacturers now. They often delay until I have no choice but to accept data sheet statistics to keep on schedule. How long will I have to wait to get Validation data?

If the product has been validated, SWR Institute will fax or mail the actual laboratory report to you within 48 hours of your request.
Are variations (plus/minus) an assurate method of joint design calculation?
Most data sheets claim a plus or minus percent movement now. I use this in my joint design calculations. Is this an accurate method?

The C 719 test must be done to validate the movement as listed in the SWR Institute Data Screen. Regardless of what may be stated or implied elsewhere on the manufacturers data sheet. Be sure you use the specific manufacturer's joint design criteria for their product on your specific application.
What if a manufacturer changes their formulation after being validated?
If the validated product is changed, it must be re-validated.
How do I know whether the validation has expired?
The date of validation and the expiration date are displayed on the SWR Institute Seal of Validation.
What if ASTM changes one of the test procedures?
If the change is significant, unexpired validated products may be required to revalidate with the new procedure. However, all testing is done with the most current test updates.
Can any type of sealant be validated?
Yes
Why are there only two tests? ASTM C 920 has many more.
C 719 and C 661 are the significant tests to show performance as a joint sealant.
Are you saying the other C 920 tests aren't as important?
All of the criteria tests of ASTM C 920 have an importance in sealant joint design. However, the two tests for validation deal with the capability of a sealant to perform as a seal, its primary function.
Are manufacturers required to validate their products?
The SWR Institute Sealant Validation Program is entirely voluntary. If you have any questions that were not answered here, please contact us (e-mail info@swrionline.org).
