Through penetration firestop systems tested to withstand movement

First firestop manufacturer to market with UL certified systems with M-ratings

Over the lifecycle of a building, movement can occur beyond the normal rigid support of penetrants through a rated assembly, which may impact the performance of firestopping. It’s important to have a method to consider movement and the impact on firestopping. ASTM – E 3037 Standard Test Method for Measuring Movement Capabilities of Through-Penetration Firestop Systems was first issued in November 2016 to provide a standardized method to assess the ability of firestop systems to experience movement and continue to be relied upon to perform their firestopping function.

At Hilti, we have conducted extensive tests according to this latest industry standard. As a result, we provide systems certified by the newly established UL certification program with M-ratings, the latest certification criteria for movement. With this we continue to commit to our ultimate purpose of helping save lives and improving building performance. 

Importance of UL certification program with M-ratings

Testing standards are constantly developing and published to accommodate the needs of the industry and ultimately improve life safety. As is the case when it comes to movement of through penetrations. An installed firestop system subjected to movement prior to fire exposure may not perform as intended in the event of a fire

Vibrations and thermal expansions of pipes, slab deflection, mechanical forces, impact and water hammer are all types of movement that can happen over the lifetime of a building due to situations like blasts, high winds, mechanical systems and floor deflections. 

In December 2019, UL published a certification based on the ASTM E-3037 Movement penetration standard. The intent of the certification program is to assess the movement capability of through penetrations such as pipes and cables passing through rated assemblies. In order to certify to these criteria, firestop systems go through a two-direction cycling test, where through-penetrations are tested in both perpendicular and parallel directions to represent movement that can be experienced over the lifetime of a building. This is followed by a fire test.  The results quantify the amount of movement firestop systems can accommodate while still performing as intended in the event of a fire.

Movement capability of firestop systems

Hilti has successfully tested and certified a variety of our systems, from those that use sealants, such as FS-ONE Max, to those that use preformed devices, such as the speed sleeve CP 653 or firestop blocks CFS-BL.

Being the first to market with 8 Underwriters Laboratories (UL) certified systems with M-ratings tested to US standard UL 1479 is important to us.  Life safety in buildings relies greatly on firestopping that performs as intended.

Hilti is committed to continuously contributing to improved life safety of buildings by developing and testing our firestop systems according to the latest industry standards.
