Standard crash tests

Tests based on standardized impact tests

As an accredited test laboratory we carry out crash tests in accordance with standards. These include:

  • Impact testing of safety barriers (e.g. concrete and steel) in accordance with EN 1317 and MASH
  • Impact testing of vehicle security barriers (e.g. bollard, barriers, wedges) in accordance with ASTM F2656/F2656M, DIN SPEC 91414-1 and ISO 22343-1, Technical Guideline – Mobile Vehicle Safety Barriers
  • Impact testing of support structures for road equipment (e.g. road traffic signs, light poles, traffic light systems, speed measuring devices) in accordance with EN 12767

The requirements of a test laboratory correspond in accordance with Article 43 of the Construction Products Regulation for the EN 1317 test methods. In addition, our accreditation by the DAkkS is internationally valid, since the German accreditation body is a member of the International Laboratory Accreditation Cooperation (ILAC).

Due to the flexible category III accreditation, we can use the free choice of standardized test methods or those that are equivalent to them within the test areas specified above and without requiring prior information and approval from the DAkkS (except EN 1317).

  • CEN/TS 17342:2019 Road restraint systems - Motorcycle road restraint systems which reduce the impact severity of motorcyclist collisions with safety barriers
  • ASTM F 3016/F 3016M:2019 - Standard Test Method for Surrogate Testing of Vehicle Impact Protective Devices at Low Speeds

Compliance statement and rule of decision

With regard to compliance statements in test reports, the following decision rules have been defined:

As a rule, a low confidence level (A) is assumed, which increases the acceptance range, so that measurement results with a confidence level of at least 50% are also accepted.

After prior agreement, the customer can also specify a medium confidence level (B), which reduces the acceptance range so that measurement results with a confidence level of at least 95% are also accepted with a maximum residual risk of 5%.

A high confidence level (C), which corresponds to a confidence level of at least 99.9%, is not acceptable at the CTS test laboratory and is therefore not applicable.

The confidence level you set (A or B) will be communicated to you via the offer and the test report.

ISO 22343-1 standard replaces IWA14-1 and IWA14-2

CTS now offers the following new test procedure:

ISO 22343-1 “Security and resilience - Vehicle security barriers - Part 1: Performance requirement, vehicle impact test method and performance rating”

IWA 14-1:2013 will be replaced by ISO 22343-1:2023 and PAS 68:2013 will only be offered upon explicit customer request.

CTS was involved in the development of the new standard and will be offering tests according to the new international standard from October 2023.

Please feel free to contact us to have your products tested this year so that you can use your product, for example. at Intersec on the 16th.-18th. January 2024 in Dubai.

At the same time, ISO 22343-2 “Security and resilience - Vehicle security barriers – Part 2: Application” was published and replaces IWA 14-2:2013.

Bird dummy for aviation: chickens no longer have to die for this

The company CTS Crashtest-Service from Münster has invented an artificial chicken. It is used in bird strike experiments - to protect life.

By Andrea Walter

It looks and feels like a chicken about to end up in a cooking pot: a bit soft, without feathers, a plastic skeleton shimmers through the silicone. Peter Schimmelpfennig and Mirko Dobberstein from CTS Crashtest Service worked on this artificial bird for a long time. It must be lifelike to be approved for bird strike experiments. That's why every chicken produced here has the same weight: 1.8 kilograms, that's the rule.

Real chickens for bird strike experiments

What hardly anyone knows: To this day, real chickens are used in the aviation industry for the prescribed bird strike tests, for example on engines. They are killed just before the attempt but must not be dead for more than 40 minutes or rigor mortis sets in and that would falsify the attempt.
