Signifi
6、cance and Use4.1 Conductive and static dissipative floors (static controlflooring) serve as a convenient means of electrically connect-ing persons and objects together to prevent the accumulation ofelectrostatic charges. A static control floor is specified on thebasis of controlled resistance values
7、. The surface of the floorprovides a path of moderate electrical conductivity between allpersons and equipment making contact with the floor toprevent the accumulation of dangerous electrostatic charges.Static control footwear will need to be used in conjunction withthe floor for the floor to perfor
8、m effectively with personnel.4.2 The resistance of some flooring materials change withage. Floors of such materials should have an initial resistancelow enough or high enough to permit increase or decrease inresistance with age without exceeding the limits prescribed inthe product specifications.5.

40、ation)X1. INTRA- AND INTERLABORATORY STUDIESX1.1 Historically, Test Method F 150 used a 500 VDC testvoltage until 1998 when it was changed to allow the option of100 VDC along with 500 VDC. The reason for having the twotest voltages was a compromise between those who wanted 500VDC only and those who
41、desired 100 VDC only. Part of thecompromise included an agreement that additional researchand testing would take place to determine the best voltage orvoltages to use when testing resilient flooring in the conductiveand static dissipative ranges. It was determined that 500 VDCwas too high to accurat
42、ely test in the conductive range withoutincreasing the amperage. Meters using 100 VDC and limited to5.0 mA are mathematically not capable of measurement below250,000 ohms. This was the basis for testing at 10 VDC and100 VDC. The test is first done at 10 VDC to eliminate thepossibility of polarizing
43、the tile and producing a false reading.Extensive testing has verified these facts.ADDITIONAL MATERIAL(1) Navships 0901-690-0002, Naval Ships Technical Manual, Chapter9690, Electrical Measuring and Test Instruments, Part 7, Accuracy 3percent of scale 25C, Naval Sea Systems Command, Crystal City,VA.(2
