Should the weak electricity and fire control room be made of anti-static floor during construction? Will it affect the acceptance later?
Test and quality inspection 1, movable floor ground testing equipment: Digital trillion ohm table: test voltage 100V, measuring range should be greater than 1 X103-1.0X1011 ohm; accuracy rating shall not be less than 2.5. Electrode: two, copper, the surface should be chrome plated, cylindrical, 63mm2.5 kg, and digital megohmmeter for supporting the use of surface resistance and anti-static ground resistance test system. The measuring electrode with conductive gasket dry sponge or conductive rubber, since the volume resistance should be less than 1.0X103 ohm. Grounding resistance meter: used to measure the grounding resistance between earth electrode and earth. The range and accuracy level must meet the measurement requirements.
Is the computer room and the fire control room must be laid in accordance with the norms of anti-static flooring, this is in accordance with the specification must be acceptance of the floor after installation, according to the design requirements along the room installation skirting board (wood, stone can be). The baseboard should be firm, flat and horizontal, and the error shall not exceed 3mm within the range of 5m.
Ruler: length should be 2m, used to check the flatness of the ground. All the equipment used for the test of antistatic performance shall be valid during the period of measurement and evaluation. 2, the test environment temperature should be between 15--30 degrees centigrade, the relative humidity should be less than 70%. 3. One end of the test electrode is placed on the surface of the floor. The other test electrode is connected to the ground terminal. 4, quality assessment methods should be (batch by batch check, count sampling procedures and sampling table) GB2828 regulations. 5, anti-static floor panel surface electrical performance indicators should comply with the following requirements: system resistance: conductive electrostatic type less than 1.0X 106 ohms, electrostatic dissipation type is 1.0X106-1.0X1010 ohm. Surface resistance: 1 X105-1.0X1010 ohm (measuring electrode spacing 900--1000mm) the system grounding resistance shall meet the design requirements. 6, anti-static floor surface layer should be soft and smooth, uniform color, should not bubble, without obvious defects; layout should be firmly pasted, there should be no glue phenomenon.
