2、to ISO 6356. 1. Purpose and Scope 1.1 This test method assesses the static-generating propensity of carpets developed when a person walks across them. This method uses controlled labo- ratory simulation of the conditions, that may be encountered in use. The simula- tion is focused on the use of thos
3、e condi- tions, which are known from experience to be strong contributors to excessive ac- cumulation of static charges. 1.2 This test method does not include standards of performance. The specifica- tion requirements pertinent to any given application can vary considerably, de- pending on the speci
4、fic demands of the application. Specifiers should give atten- tion to the variability of the method as de- scribed below in Section 11. 2. Principle 2.1 Build-up of a static charge on a person walking across a carpet under conditions of low atmospheric humidity has been recognized as a classic examp
5、le of the triboelectric effect, whereby a sep- aration of electrical charges is produced when two dissimilar surfaces in contact are separated. The magnitude of the charge separation and the resultant volt- age on the person vary under the influ- ence of many factors. The most important factors for
6、the purpose of this test are: (a) the chemical and physical charac- teristics of the two materials brought into contact, rubbed and separated; i.e., the shoe soles and carpet; (b) the surface contamination on one or both; (c) the nature of the rubbing and/or separation, i.e., the method of walk, in-
7、 cluding the height of the shoe above the carpet; and (d) the ambient conditions (especially the relative humidity). 2.2 A carpet brought to moisture equi- librium at controlled atmospheric condi- tions is walked on by a test operator in a specified manner with specified shoe soles and heels. The st
8、atic charge, which builds up on the operator, is monitored continuously by a voltage indicator with a recorder. 2.3 The maximum voltage, generated on the person by the accumulated charge, measured during the test period is defined as the static-generating propensity of the carpet under the condition
9、s of the test. 3. Terminology 3.1 electrostatic propensity, n.the ability to produce and accumulate an electrostatic charge. NOTE: For the purposes of this test, it is the resultant voltage on a person walk- ing across the surface of a textile floor covering under specified conditions, which has bee
10、n caused by the accumula- tion of an electrostatic charge on the body. 4. Safety Precautions NOTE: These safety precautions are for information purposes only. The pre- cautions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. It is the users responsibility to use
11、 safe and proper techniques in handling materials in this test method. Manufac- turers MUST be consulted for specific details such as material safety data sheets and other manufacturers recommenda- tions. All OSHA standards and rules must also be consulted and followed. 4.1 Good laboratory practices
12、 should be followed. Wear safety glasses in all laboratory areas. 4.2 All chemicals should be handled with care. 4.3 Isopropyl alcohol is a flammable liquid and should be stored in the labora- tory only in small containers away from heat, open flames and sparks. 4.4 Manufacturers safety recommen- da
13、tions should be followed when operat- ing laboratory testing equipment. 4.5 Ground all electrical equipment. 4.6 High-voltage sources should have an internal impedance of not less than 1 108 ohm (or the maximum output current lim- ited to 1 milliampere) to avoid shock haz- ard in calibration of the
14、detection system. 5. Apparatus and Materials 5.1 A room that can be maintained at a temperature of 21 1C and at 20 2% RH, and suitable means for monitoring these conditions. Special requirements of end-use may dictate the use of other test- ing conditions (e.g., for aircraft or for con- trolled-humi
15、dity environments) and the test facility should be capable of achieving and maintaining those conditions. 5.1.1 The room should be of such di- mensions and so arranged that the test op- erator comes no closer than approxi- mately 600 mm to extraneous grounded or charged surfaces (such as walls or wo
16、rkbenches) during testing and should be equipped with open-wire shelves, racks or horizontal rods suitable for hang- ing carpet samples for conditioning. Air must pass freely around all surfaces of the samples to facilitate moisture equili- bration. 5.2 Test sandals should be used only for testing c
17、arpet. New test sandals should be cleaned before use as pre- scribed in 8.7.1. Soles must be attached to the sandals by gluing and/or stitching. Tacks or rivets must not be used. 5.2.1 One pair of AATCC TM 134 san- dals (see 12.1) manufactured with XS 664 P-HK Neolite soles. A second pair of Neolite
18、 test shoes or sandals with self-ad- hesive (i.e., replaceable) suede leather at- tached to the shoe sole. The second pair of Neolite shoes or sandals must be dedi- cated to this use only. 5.2.2 Reagent grade isopropyl alcohol and cheesecloth. 5.3 Electrostatic detection and record- ing means for vo
19、ltages up to at least 20 kV (see 12.2). 5.3.1 The system should have a high input impedance and be suitably damped such that a steady recorder or meter indi- cation of 3000 V will, when the input is grounded, decay to 1500 V in not less than 1 s or more than 3 s (this corre- sponds to a time constan
20、t of 1.4-4.3 s). To achieve reasonable accuracy in use, the input capacitance, including lead-in wire, should not exceed 30 pF. (See Appendix A for additional information on measure- ment of damping and Appendix B for in- formation on damping techniques.) 5.4 A grounded metal plate approxi- mately 1
21、200 1200 mm. 5.5 A standard 1350 g/m2 rubberized jute/hair cushion underlay (see 12.1) at least 1200 1200 mm. The vertical resis- tance through the cushion shall not be less than 1012 ohms (see 12.6). 5.6 A set of AATCC TM 134 AATCC Static Control Carpets (see 12.1) consist- ing of static unprotecte
22、d and static pro- tected versions. 5.7 An optional metronome. 5.8 An optional handheld blowing-fan balanced ionizer. 6.
