ANSI E1.34-2009 pdf download Entertainment Technology Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues
1 Scope This standard describes means of measuring and specifying the slipperiness of floor surface materials used by performers in live entertainment venues. The standard is not intended to be applied to normal walking and working surfaces, but only to those floor surface materials used by actors, dancers, and other similar artists when rehearsing or performing.
2 Application This standard offers two procedures for measuring and specifying the slipperiness of floor surface materials used by performers to address particular measurement problems. The two testing procedures are to address two different uses for measurements of floor slipperiness. The first testing procedure, the General Testing Procedure, is intended to render a number that can be used in comparing the relative slipperiness of floor materials when the friction materials are the floor surface and stainless steel.
It is likely to be useful for marketing purposes and for comparisons between floor materials, but it may not be representative of the slipperiness experienced by a performer in a particular situation, since the performer is unlikely to have footwear with soles and heels made of stainless steel. The second testing procedure, the Specific Testing Procedure, provides a means of rendering a slipperiness number for a floor surface when specific footwear material is contacting it. This procedure may be useful for helping solving problems when a performer reports that a floor is too slippery or too sticky by allowing objective measurement of the slipperiness. Having an objective measurement can help facilitate finding different floor or footwear materials that are less slippery or sticky to satisfy the performer. Clauses marked with an asterisk have a corresponding explanatory note in Annex A. The note has the same clause number but has an “A.” prefix. All the explanatory notes in Annex A are informational and do not add or remove any requirements from this standard.
3 Basic Test Equipment The basic test equipment consists of a dragsled, a spring balance or force gauge, and a push stick, which serves as a means of drawing the dragsled across a sample of floor surface material.
