1、Designation: F 609 05An American National StandardStandard Test Method forUsing a Horizontal Pull Slipmeter (HPS)1This standard is issued under the fixed designation F 609; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers measurement of the slip indexof footwear sole, heel, or related materials on dry walkwaysur
3、faces in the laboratory and in the field.1.2 The dimensional values used in the test method aregiven in units of inches, pounds, or degrees Fahrenheit.Alternative equivalent values are in parentheses and are forinformational purposes only.1.3 This standard does not purport to address all of thesafet
4、y concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

5、Interlaboratory Study toDetermine the Precision of a Test MethodF 1646 Terminology Relating to Safety and Traction forFootwear3. Terminology3.1 For definitions of terms, refer to Terminology F 1646.4. Significance and Use4.1 The Horizontal Pull Slipmeter3is a laboratory and fieldinstrument designed
6、to provide information about the slipindex characteristics between walkway surfaces and a test footmaterial under dry conditions only. The HPS can not be usedon wet surfaces. Slip index can be affected by surface rough-ness, presence of water, contaminants such as grease and otherforeign materials,
7、and floor surface wear over time. Slip index,as determined by the HPS, most likely will not give usefulinformation for evaluating liquid contaminated surfaces, andtherefore, will not provide an effective assessment of a poten-tial slipping hazard on a walkway surface under these condi-tions.4.2 The
8、value reported by the Horizontal Pull Slipmeter iscalled the slip index. Slip index is ten times the staticcoefficient of friction. For example, a static coefficient offriction of 0.4 is displayed by a slip index of 4.0 whenmeasured by the Horizontal Pull Slipmeter.4.3 The HPS can be used on incline
9、d surfaces. No adjust-ment for slope is needed for measurements in the directionperpendicular to the slope and when averaging four measure-ments at one location taken according to step 10.14.5.

11、hoe materials, Neolite5shouldbe replaced with the desired test materials.7.2 A set of three test feet of the same material are requiredfor performance of the test.8.

18、ken, PA 19428-2959, United States.Chatillon DPP-5 gages. Later model gages have replaced theswitch button with a peak hold mode feature.8.2 Grasp the slipmeter and hold in vertical position.8.3 Set the gage on zero by moving the rim on the gage.8.4 Use a separate hook to suspend the slipmeter by the
19、hook located on one end of the slipmeter. The slipmeter shouldhang freely.8.5 The needle on the dial of the gage should be withincalibration range as indicated on the dial. If it is not within thecalibration range, the HPS should be sent to the manufacturer4for calibration.9. Conditioning9.1 For tes
20、ting in laboratories, condition test feet for at least18 to 24 h in atmosphere maintained at 73 6 3.6F (22.8 62C) and 50 6 5 % relative humidity.9.2 When testing feet in the field or on fixed floor surfaces,conditioning of test feet in accordance with 9.1 may not bepossible. The results obtained dur
21、ing the ruggedness testindicated that temperature could have a significant effect on themeasured slip index when tested at 50 and 85F. Interpolationhas not been established to make proper adjustments fordifferent temperature and humidity. However, it is recom-mended that the temperature and humidity
22、 be recorded, sincethese records could help explain potential inconsistencies.10. Procedure10.1 Insert a set of three test feet in the slipmeter recesses.Test feet can be held in place using all purpose glue.10.2 Mount the abrasive paper on a flat 3 by 7-in. (76.2 by77.8-mm) piece of 0.5-in. (12.7-m
23、m) plywood.10.3 Sand the test feet with No. 400 abrasive paper. Thesanding procedure should consist of five strokes of 5 to 6 in. inlength, parallel to the friction measurement direction, followedby five strokes of 5 to 6 in. in length, perpendicular to thefriction measurement direction.10.4 Lightly
24、 brush the test feet using the non-static brush toremove loose surface particles.10.5 Place the slipmeter on its feet on the test walkwaysurface. The hook end shall face the power unit. Be sure allthree test feet rest on the level walkway surface and not on agrout joint or other uneven surface.10.6
25、Place the slipmeter power unit on the walkway surfacein front of the slipmeter.10.7 Put the switch that permits retention of maximum slipindex indication in the center position. For later model Chatil-lon DPP-5 gages with no switch, ignore this step.10.8 Set the slip index meter on zero by rotating
26、the bezeluntil pointer meets zero on dial. For later model gages with noswitch, use black knob on dial to set red needle on zero withblack peak hold needle immediately to right.10.9 Push the switch on top of the gage toward the hooklessend of the slipmeter to record the maximum. For later modelgages
27、 with no switch, ignore this step.10.10 Connect the string of the power unit pulley to thehook of the slipmeter. The string should be parallel with the testsurface and in line with the pulley on the power unit. Align thepulley on the power unit with the hook on the slipmeter. Besure to keep the stri
28、ng alignment from the pulley straight (0 to5) with the hook on the slip meter. The string length betweenthe pulley and the hook of the slipmeter should not be tooshort, that is, no less than 4 in. or no more than two loopsaround the pulley.10.11 Hold down the power unit with one or both hands toprev
29、ent it from moving; then depress the switch.NOTE 1 Do not exceed 10 min dwell time between placing the testfeet in contact with the walkway surface and slip index measurement. Thisdwell time is the time needed from 10.5 to and including 10.11. Slip indexshould be measured within 30 min after sanding
30、 and brushing, detailed in10.3 and10.11.NOTE 1Total weight of slipmeter less power unit is 5.95 6 0.07 lb (2700 6 34 g). Speed of power unit is 3.5 6 0.5 in./min. Later model ChatillonDPP-5 gages do not have a switch. Peak hold feature is found in the gage dial.FIG. 1 Horizontal Pull SlipmeterF60905

Record slip indexreadings in excess of 8 as 8.10.14 Repeat 10.5 through 10.13 for a total of four times foreach location. Rotate the slip
32、meter 90 in the same direction(clockwise or counterclockwise) after each time.11.
