New home decoration to their own wiring, but I do not know or the first cloth pvc tube, or pvc tube and line synchronization? If the pvc tube first all cloth, but how to wear into the line? Is it easy to thread? Cloth pvc tube is not to be arranged within a few meters a junction box? Want to understand the people to help answer. Copy is free. Question added: the line is good or the wall is good? Will the floor tiles affect the floor load? More
On behalf of you to take that type of test all the cables, of course, must be the same manufacturer. The same model. The same batch of production date to produce the product!
. on behalf of the kind of test to take the same manufacturers, the same model, the same batch of production date to produce all the cables. . refers to the relevant laws and regulations, the construction of mandatory standards and design documents, the construction of the project materials, structural parts, equipment, as well as the quality of engineering entities, the use of functional testing to determine its quality characteristics of the activities. Mainly covers roads, bridges, construction, electricity, nuclear power, railways, ships, special equipment. The main means of detection for non-destructive testing technology Nondestructive testing is an indispensable tool for industrial development, to a certain extent, reflects a country's industrial development level. . China in November 1978 set up a national non-destructive testing academic organization - China Mechanical Engineering Society of non-destructive testing branch. In addition, metallurgical, power, petrochemical, shipbuilding, aerospace, nuclear energy and other industries also set up their own non-destructive testing societies or associations; some provinces, autonomous regions, municipalities and prefecture-level cities set up provincial (city) Societies or associations; northeast, east, southwest and other regions also set up a regional non-destructive testing societies or associations. In the basic theory of non-destructive testing and equipment development, China and the world's advanced countries still have a big gap between, especially in the infrared, acoustic emission and other high-tech testing equipment is even more so.
When not specified, it usually refers to the reporting of all the wires that require testing
