25、electrical resistance of all types of floor coverings and installed floors with resistance to ground, point-to-point resistance and vertical resistance of between 10 4 and 10 13. Laboratory evaluations carried out under controlled environmental conditions can be used for classification or quality co

26、ntrol purposes. Tests on installed floors under uncontrolled ambient conditions can be used to determine correct installation or as part of an ongoing system verification. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、 the test material is measured using a high-resistance meter, or other suitable equipment. Point-to-point resistance measurements are appropriate for evaluating a floor coverings ability to conduct charge across its use-surface or to act as a charge sink. Measurements of resistance through floor cov

33、erings, i.e. resistance to ground and vertical resistance, are appropriate for evaluating their ability to conduct charge from the use-surface or from conductors in contact with the use-surface, to a charge sink beneath the floor covering. A simulation of the resistance-to-ground measurement is made

34、 under laboratory conditions by attaching a groundable point to the back of the floor covering under test. 5 Apparatus 5.1 Resistance measuring apparatus This apparatus consists of a self-contained resistance meter (ohmmeter) or power supply and current meter in the appropriate configuration for res

35、istance measurement, with a 10 % accuracy, and capable of the following requirements. 5.1.1 Laboratory evaluations The apparatus shall have a circuit voltage while under load of 10 V 0,5 V for resistance below 1,0 10 6 100 V 5 V for resistance between 1,0 10 6 and 1,0 10 11 500 V 25 V for resistance

36、 above 1,0 10 11 The measuring range of the apparatus shall be at least one order of magnitude on either side of the expected range of resistance being measured. The apparatus shall be used in a manner that ensures that unintended ground paths do not influence measurements. Page5 EN613404:2004Page5

38、 0,5 V for resistance below 1,0 10 6 100 V 5 V for resistance between 1,0 10 6 and 1,0 10 11 500 V 25 V for resistance above 1,0 10 11. The measuring range of the apparatus shall be at least one order of magnitude on either side of the expected range of resistance being measured. The apparatus shall

39、 be used in a manner that ensures that unintended ground paths do not influence measurements. In case of dispute, laboratory evaluation apparatus shall be used. 5.2 Measuring electrodes The measuring electrodes consist of two cylindrical metal electrodes (preferably stainless steel) with terminals f

40、or connecting to the resistance measuring apparatus. Examples of suitable electrodes are shown in Figure 1. Each electrode shall have a flat circular contact area of 65 mm 5 mm in diameter. For measurements on hard, non-conformable surfaces, the contact area shall be a conductive rubber pad with a S

41、hore A durometer hardness of 60 10. The contact resistance of each measuring electrode fitted with a conductive rubber pad shall be less than 1 000 , measured by placing the measuring electrode directly on the counter- electrode (see 5.3). For conformable surfaces, textile floor coverings, for examp

42、le, the conductive rubber pad need not be used, the contact area then being the bottom surface of the metal electrode. The total mass of each measuring electrode shall be either a) 2,5 kg 0,25 kg for measurements on hard, non-conformable surfaces; or b) 5,0 kg 0,25 kg for measurements on all other s

43、urfaces. NOTE A circular disc of insulating material with vertical resistance greater than 10 14 may be used as a support platform for additional weights (see Figure 1). 5.3 Counter-electrode The counter-electrode consists of a flat stainless steel plate, 600 mm 10 mm square and of 1 mm (nominal) th

44、ickness, with a terminal for connection to the resistance measuring apparatus. 5.4 Support plates For point-to-point resistance measurements, where required (see Clause 6) and resistance to ground measurements: support plates shall be equal in area to the test specimens, of sufficient rigidity to ho

45、ld specimens together for testing, and made from insulating material with a vertical resistance greater than 10 14. For vertical resistance measurements, where required (see Clause 6): flat metal plates, equal in area to the test specimens and of sufficient rigidity to hold specimens together for te

46、sting, shall be used.

47、m thick, made from insulating material with a vertical resistance greater than 10 14 shall be used. For point-to-point and resistance to ground measurements: a flat plate 1 300 mm 10 mm by 600 mm 10 mm, 5 mm 1 mm thick, made from insulating material with a vertical resistance greater than 10 14 shal

48、l be used. 6 Sampling for laboratory evaluations Selection and sampling of test materials shall be carried out according to ISO 1957. Although ISO 1957 is intended for textile floor coverings, its principles are relevant to other types of floor covering. For vertical resistance measurements, three s

49、pecimens shall be tested, each being 500 mm 50 mm square. For point-to-point and resistance to ground measurements, two specimens shall be tested, each being 1 200 mm 50 mm by 500 mm 50 mm. Where directional differences may exist, one specimen shall have its long side parallel to the machine direction
