Certified safety

ZZ-Certificate DIN ISO 9001

ZAPP-ZIMMERMANN GmbH is a company certified in accordance with DIN ISO 9001. Successful annual surveillance audits, conducted by TÜV Rheinland, demonstrate the high priority placed on quality management in our company and our ongoing commitment to the highest quality.

ZZ-Certificate MPA

Moreover, all of our tested and certified products are subject to regular external monitoring by the materials testing institutes, MPA Stuttgart and MPA Braunschweig. Employees of the materials testing institutes inspect the self-monitoring data and take product samples that are tested in the laboratory of the materials testing institute. Thus, you can be sure that all products always satisfy the specifications of the general technical approvals and assessments.

ZZ-Certificate CE

Our European approved products have a EC-Certificate of conformity issued by MPA Braunschweig and are CE marked. With that it is verified and confirmed that the products have been subjected to initial inspection, and are subjected to factory production control. In addition, an external inspection takes place yearly.

Certificated UL

Our UL classified products are listed by UL. Representative samples of these products have been evaluated by UL and meet applicable safety standards.

Approval Overview

ZZ-National Approvals

National approvals

In Germany, for more than 25 years, ZAPP-ZIMMERMANN has been using fire-protection systems that are approved by the Deutsches Institut für Bautechnik (DIBt). After successful testing the test report is submitted to the DIBt, thereafter a “technical approval” (AbZ) is received for the tested system. We have additional approvals for our fire-protection systems for Switzerland (VKF), The Netherlands (Efectis) and Great Britain (Warrington Fire).

ZZ-ETA Approvals

European Technical Approvals / European Technical Assessments

The European Organisation for Technical Assessments (EOTA) was founded in the course of European harmonization, this organisation works out the fundamentals for granting European Technical Assessments (ETA). All European assessment bodies are represented in the EOTA (OIB, DIBt, etc.).

The assessment bodies issue a European Technical Assessment for systems, which can be tested in centers of notified test bodies. Through the introduction of ETAs, european test standards and uniform classifications fire-protection systems can be used throughout Europe. Each Member State is free to specify its level of safety in the construction sector, as well as the requisite classifications and supplemental requirements for construction products.

UL Approvals

UL Systems

There is a UL promulgated system for each of our ZAPP-ZIMMERMANN Fire Stop Systems applications according to ASTM E 814 (ANSI/UL 1479) “Standard Test Method for Fire Tests of Through-Penetration Fire Stops.” A firestop system is a very specific, tested combination of the following parameters: substrate (wall or floor) and its specific properties (e.g., material, fire rating, thickness), penetrating items, hole size and shapeand devices, and/or materials used to seal the hole.

To evaluate firestop systems’ compliance with the US and Canadian codes, they are frequently tested by independent third-party test labs such as UL (Underwriters Laboratories) and ULC (Underwriters Laboratories of Canada). Successfully passing the test results in a UL promulgated firestop system. The last item above - the individual devices and/or materials used to seal the hole, colloquially referred to as firestopping - is a UL Classified or Certified product for the application.
