10、nment industry in technical standards related matters. The goal of the Program is to take a leading role regarding technology within the entertainment industry by creating recommended practices and standards, monitoring standards issues around the world on behalf of our members, and improving commun

11、ications and safety within the industry. ESTA works closely with the technical standards efforts of other organizations within our industry, including USITT and VPLT, as well as representing the interests of ESTA members to ANSI, UL, and the NFPA. The Technical Standards Program is accredited by the

12、 American National Standards Institute. The Technical Standards Council (TSC) was established to oversee and coordinate the Technical Standards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Council approves all projects undertaken and assigns

13、them to the appropriate working group. The Technical Standards Council employs a Technical Standards Manager to coordinate the work of the Council and its working groups as well as maintain a “Standards Watch” on behalf of members. Working groups include: Control Protocols, Electrical Power, Event S

14、afety, Floors, Fog and Smoke, Followspot Position, Photometrics, Rigging, and Stage Lifts. ESTA encourages active participation in the Technical Standards Program. There are several ways to become involved. If you would like to become a member of an existing working group, as have over four hundred

15、people, you must complete an application which is available from the ESTA office. Your application is subject to approval by the working group and you will be required to actively participate in the work of the group. This includes responding to letter ballots and attending meetings. Membership in E

16、STA is not a requirement. You can also become involved by requesting that the TSC develop a standard or a recommended practice in an area of concern to you. The Floors Working Group, which authored this Standard, consists of a cross section of entertainment industry professionals representing a dive

17、rsity of interests. ESTA is committed to developing consensus-based standards and recommended practices in an open setting. 2017 ESTA ii Floors/2006-8013r3a ANSI E1.34, Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues Contact Information Technical Standards Manager

27、easuring 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 re

28、hearsing 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 sli

29、pperiness. 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

30、 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 Proce

31、dure, 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 slipp

32、eriness. 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.“

33、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 acro

34、ss a sample of floor surface material. 3.1 The dragsled 3.1.1* The dragsled shall be a rigid body, approximately 240 mm long by 120 mm wide, with a uniformly distributed mass of 5 kilograms, plus or minus 25 grams. 3.1.2 The dragsled shall be supported on three cylindrical stainless steel feet, each

35、 machined at the tip to provide a flat bearing surface of 7 mm diameter and provided with a chamfer of 2 mm radius to allow the test foot to slide unimpeded across the test piece. 3.1.2.1* The stainless steel feet shall be made of type 304, X5CrNi18-10, or 18/8 stainless steel alloy. 2017 ESTA 1 Flo

37、 leading edge of the dragsled, which is the edge closest to the foot at the apex of the isosceles triangle, shall have a means to attach the sled to a flexible cotton, nylon, or polypropylene multi-strand cord, 2 to 4 mm in diameter. 3.2* The Spring Balance or Tension Gauge The spring balance or ten

38、sion gauge shall be able to measure a range of forces from zero up to a force equivalent to the weight of the dragsled with measurement increments equivalent to 50 grams or smaller. 3.3* The Pushstick The pushstick serves as a means to manually move the dragsled across the floor surface. 3.3.1 The p

39、ushstick shall consist of a long handle attached to a freely turning wheel (or wheels) that can roll along the floor. The handle shall be long enough to allow a person to walk upright, pushing the pushstick ahead of him or her, with the handle at about a 45 degree angle from the horizontal. 3.3.2* A

40、 freely turning pulley shall be mounted near the wheel (or wheels) at the bottom of the handle. A flexible cotton, nylon, or polypropylene multi-strand cord, 2 to 4 mm in diameter, shall run parallel to the floor from the dragsled to the pulley, through the pulley, and up to the spring balance or te

41、nsion gauge. The pulley shall have a sheave diameter that is at least 12 times the cord diameter. 3.3.3 The spring balance or tension gauge shall be mounted at the top of the handle in such a manner that it is easily read and easily operated if it has any controls. 2017 ESTA 2 Floors/2006-8013r3a AN

45、, ensure the area of the floor surface to be tested is wiped clean with a dry cloth to remove any dirt, dust, or other contaminants. 4.1.2 If the test is to be conducted on floor surface material as it is used in the field, do not clean the material but test it as it is in the field. 4.1.3 The floor

46、 surface material to be tested shall be mounted or held in a horizontal position. 4.1.4 If the floor surface material to be tested is flexible, it shall be supported by a rigid, flat, horizontal surface. 4.1.5 Ensure that the stainless steel test feet are clean. Also ensure that the solution used to

47、 clean the feet is removed. 2017 ESTA 4 Floors/2006-8013r3a ANSI E1.34, Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues 4.2* Weighing the dragsled Figure 4.2 Weighing the dragsled Notice that the angle between the cord running from the sled to the pulley and from

48、the pulley to the spring balance or force gauge is the same as the angle shown in Figure 3.3. The dragsled shall be weighed with the spring balance via the cord and pulley on the pushstick, with the dragsled hanging below the pulley. The angle between the cord running from the sled to the pulley and

49、 from the pulley to the spring balance or force gauge shall be equal to the angle when the pushstick is used with the wheel on the floor, as shown in Figure 3.3, within the tolerances shown in Table 4.2: 2017 ESTA 5 Floors/2006-8013r3a ANSI E1.34, Measuring and Specifying the Slipperiness of Floors Used in Live Performance Venues Angle with wheel on floor, pulling the dragsled Angular range when weighing the dragsled 60 de
