Wartenberg Pendulum Test Assessment Overview Assessment Area ICF Domain: Body Function Subcategory: Neuromusculoskeletal & Movement-related Functions and Structures Summary The Wartenberg Pendulum Test was introduced in the 1950s as a diagnostic tool of spasticity. It was originally a qualitative measure (clinician simply observed the leg swing). The Pendulum Test is an established reliable method.

The compound pendulum, on the other hand, is a rigid body that is pivoted so that it can oscillate freely. An advantage of pendulum slip tests is that there are many situation-specific safety standards, e.g. wet Pendulum Test Value (or DCOF rating) of 12 or higher for normally dry areas; 35 or higher for fresh fruit and vegetable areas in supermarkets; or 55 or higher for external ramps with slopes steeper than 1 in 14 (4.1 degrees). These are The pendulum slip resistance test is well-researched and long backed by the ASTM (American Society for Testing and Materials) standard E303 that was validated and has been in use since 1971. 3500 test results on walking surfaces were obtained over more than 25 years to validate this test method.
In the test the yoke is stopped by the impact tensile fixture, while the pendulum plus specimen continues its travel. An impact tensile fixture is available for each standard.
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemin

A simple pendulum consists of a relatively massive object - known as the pendulum bob - hung by a string from a fixed support. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion. The pendulum tester was originally designed by Percy Sigler in the USA in the 1940s for the U.S Bureau of Standards, to test pedestrian surfaces. It was adopted and further developed in the late 1950 / 60s in the United Kingdom by the then Road Research Laboratory (RRL, now known as the Transport Research Laboratory, TRL).

With the HIT450P pendulum impact tester (450 joules), Charpy, Izod, Brugger, impact tensile and wedge impact tests can be performed to all established standards including DIN 50115 and DIN 51233, or ISO 148, ISO 14556 and ISO 8256. In addition, all international standards such as EN, ASTM and BS can be tested.

The pendulum test assesses the friction offered by a floor surface when a foot comes into contact with it. It can measure slip potential of both dry, wet and contaminated flooring. Why use the Pendulum Test? The test is the subject of a British Standard (BS 7976: Parts 1-3, 2002) and has is recommended by the HSE (Health and Safety Executive).
