The Most Tested Expansion Joints in the Industry

PRODUCT TESTING
The Most Tested Expansion Joint Systems In the Industry

We talk about it in our Newsletter publication, it is on various literature we offer, and we discuss it at each weekly organizational meeting. This statement is not just a slogan; it is a critical part of our mission, which is to provide the highest quality product to our customers, when they need it, where they need it.

What’s New?

This year our objective is to continue our testing program and to expand it to new areas. EMS has built a testing track at our facility in Akron, NY. This test track is designed to accept each expansion joint system we offer. Various joint recesses have been prepared for the different joint system configurations.

Our goal is to test each of our joint systems as they are installed for use on projects and subject them to a rigorous program of cycle testing and traffic loads. The traffic loads will be replicated with the use of our weighted motorized vehicle. This vehicle can be loaded to simulate many different vehicular weights and speeds.

As information is gathered, EMS will discuss our findings in our quarterly EMS NEWS LETTER. To get on our mailing list contact EMS, either on our web site or call us at 716/542-3991.




The above is our JP-500 seal at full pull, 13.5”

	The photo below shows the CR-325 being cycle tested to ASTM D-1399.

THE FULL PULL!

Joint seal JP-250 shown in tension to 100%, the seal is 2-1/2” wide in the relaxed state. In the above photo, the seal is pulled to 5-1/4” without a sign of failure. 1,000,000 test cycles were run on this part.

COMPUTER RUN TESTING

The photo to the left shows a seal sample being setup for the start of a pull cycle test. The computer run program documents the number of cycles, the duration of each cycle and the length of the cycle stroke.

The results are then reviewed and stored for future reference.

Seismic Movement Replication

Renewed cycle testing, of our seismic floor and seismic wall systems, which will now be concurrently, tested with Erie’s, fire barrier protection in place. Previous testing had only run each component separately; this year’s new approach is to test our systems, as they will be used in the field.

Multiple axis of movement will be cycled to 50% in each direction, to illustrate the flexibility and durability of the components as well as the system. For more information on our seismic expansion joint systems and our test results, contact EMS.

PRODUCT TESTING – ASTM E1399
STANDARD TEST METHOD FOR CYCLIC MOVEMENT AND MEASURING THE MINIMUM AND MAXIMUM JOINT WIDTH OF ARCHITECTURAL JOINT SYSTEM

The ASTM E1399 test method covers testing procedures for architectural joint systems. The test methods intended for the following uses for architectural joint systems.

To verify movement capability information supplied to the user by the producer.

To standardize comparison of movement capability by relating it to specified nominal joint widths.

To determine the cycle movement capability between specified minimum and maximum joint widths without visual deleterious effects.

To provide the user with graphic information, drawing or pictures in the test report, depicting them at minimum, maximum, and nominal joint widths during cycling.

As part of an overall quality system, a sample from each manufactured product “lot” are tested to the requirements of ASTM E1399. The results of the test are documented by “lot number” and maintained by EMS. The lot number for the product is traceable to a specific job or product that EMS provides materials. This assures that the product provided to customers meets the ASTM specification. Copies of the test report for particular product lot will be provided to the customer upon request.


	The picture to the left shows the cycle testing of our AR-Series Color seal and lubricant/adhesive. Each lot of seal is put through this process to assure quality products are offered to our customers. This documentation is kept on file for future reference.
