ASTM-F489 James Shoes Anti-Slip Tester
How can we help? The machine and associated test methods have gained wide acceptance in the global footwear industry, with sales made to brands, manufacturers, test laboratories and institutes around the world.
The is the testing method which was specific to the English XL tribometer. This testing method was also specific to a device called the Brungraber Mark II.
This standard, rather than specifying a method, provides a framework under which tribometers can be validated. Because of the leather pad specification and problem with sticktion, this method should not be used for wet testing.
The footwear is mounted on a foot forme which, in turn is mounted onto the loading frame. Various combinations of floor and footwear are possible. View comments provided f48 High Safety Consulting Services. F4489 method evaluates wet and dry conditions.
In Europe, the US and in many other countries around the world, there are a growing number of legal obligations requiring retailers to r489 place safe products on the market.
The machine console incorporates a data acquisition computer, which gives graphical output and full numerical results. To be meaningful, walkway tribometer results must correlate the slip characteristics of a surface or contaminant, or both, to the actual propensity for human slips. Footwear set in STM cradle prior to slip testing. A proposed standard for Subpart D does make a reference to a 0. The method utilizes the whole shoe, so it seems to offer a more complete picture than those methods which require sections of the footwear to be tested.
SATRA offers wstm wide range of unique member services and products designed to enhance technical knowledge and help improve profitability and global sales. ASTM F To be meaningful, walkway tribometer results must correlate the slip characteristics of a surface or contaminant, or both, to the actual propensity for human slips.
ASTM Slip-Testing Methods – HighEHS
The method understates the slip-resistance when used in wet testing. The testing method however, is still valid and an effective way to evaluate hazards on floors. If you are a SATRA member but not yet registered for online access please register as a new user below. The method uses a Mark I, which are not readily produced.
Using the new ASTM slip standard
Because most slips and falls occur on contaminated water surfaces, the value of measuring dry COF is limited. This term is largely left undefined. The method can be used on nearly all surfaces. This method uses the stationary James Machine. It is common to test footwear against a dry floor and wet floor and, in some cases, a surface with a defined lubricant.
The proliferation of 4f89 creates confusion by both consumers of slip-resistance testing services and astmm those offering such services. The SATRA STM has been developed with the benefit of extensive research into slip and slip testing methods, together with the experience gained from the daily practical use of the machine in the SATRA footwear testing laboratories.
The coefficient of friction is defined as the ratio of the horizontal force to the vertical force as the shoe slips. Hence, a low coefficient of friction indicates that only a low horizontal load would be needed to cause the shoe to slip against the flooring type used in the test.
Over this period, fundamental principles of slip have been identified, as well as the characteristics of footwear required to reduce the risks of slip. During the period when this section was open for comment, the company president, provided comments to OSHA on the reasons to retain the provision in the regulation s.
However, this standard was never promulgated as a final rule. A section of calibrated standard flooring, an alternative floor surface, asym a special surface such as ice is placed onto the floor carriage.
