Whenever the water and electricity are checked and accepted, the owners follow the supervision in a circle. They often feel that they are powerless and have a small white decoration. As the owner, you must have a certain understanding of the decoration acceptance knowledge, and you can solve the small decoration problems in the future. So, what are the acceptance specifications for home improvement hydropower ? Below, the editor lists an acceptance form to take a look at common home improvement hydropower acceptance specifications .
1. Circuit Engineering for the Installation and Acceptance Standards for Home Improvement
1. All circuit wires must wear PVC pipes. If any exposed wires are found, they must be re-constructed.
2. If there is a sky canopy or a force-reducing wall, it is recommended that the line go through the wall instead of the ground.
3. When laying the circuit, the same circuit wire should be laid in the same pipe, the diameter of the wire is determined according to the actual situation, and the total number of pipes + area should not exceed 40% of the area of ​​the PVC pipe. It is strictly forbidden to force the arrangement into the pipe.
4. When the circuit is routed, the bend shall not exceed 90 °. If it exceeds 90 °, it must be connected with pipe fittings.
5. Circuits, strong and weak electricity must be clearly distinguished, and must not wear the same tube.
6. The joint of the wire should be firm and the insulation measures should be done well, and the resistance value should be> 0.5MΩ.
7. The overall layout of the line is clear, reasonable and particular.
8. The position and height of the switch and socket must meet the conventional requirements. That is, the switch is 1200-1300mm from the ground, and the socket is 300-450mm from the ground.
9. When the indoor area exceeds 40 square meters, the air conditioner wire should be 4 square millimeters of BV copper core wire.
10. For the socket of general household appliances, 2.5 square millimeters of BV copper core wire should be laid; the lighting circuit is also of this specification, but its branch line should be 1.5 square millimeters of BV copper core wire.
11. For rooms with a suspended ceiling design, the wiring must pass through pipe fittings and cannot be placed on the suspended ceiling. It should be 100-200mm away from the ceiling.
12. If there is a laying of hidden line pipe, the thickness should not be less than 15mm when making cement grouting.
13. All household lines must be grounded and have leakage protection facilities.
14. There must be no joints for the wires running in the pipe.
2. Waterway engineering of home improvement hydropower acceptance specification
1. The water pipe joints must be firm and well sealed. This should be paid attention to during construction.
2. The outlet of the clear water pipe must have a clear distinction between hot and cold water, the conventional is to cool up and down, left and right.
3. There are concealed pipelines that pass through the indoor space, and they must undergo a pressure test before the subsequent construction can be carried out. The working pressure of the water pipe should not be lower than 0.6MP4, and the standard can only be met if there is no decompression.
4. At the interface between the faucet and the pipe fittings, the raw material tape shall be standard.
5. The extension line on the outlet pipe should be perpendicular to the wall.
6. The waterproof coating must be brushed evenly, evenly, without cracks and without shell.
7. The test of waterproof engineering is based on the standard that there is no leakage for 24 hours after the water is turned off.
Summary of the article: The above are all the contents of the home improvement hydropower acceptance specifications and where the hydropower acceptance is checked. The above hydropower acceptance specifications can be used as a reference. After all, different regions may have different standards.
