Electrician Pipes Technology Performance
NO. Items Performance requirements

1 Voluntary standards
GB/T14823.2-93

2 Appearance
Both the inside and outside surfaces of the pipes should be smooth, without blowholes, overt openings or unidenticl color. The mouth of pipes should have smooth edges so as not to scratch the insulating layer of cables. The color is white.
