2.3　Division of Construction Quality Acceptance for Electrical Equipment Installation Engineering in Metallurgy

2.3.1　The acceptance of construction quality of electrical equipment installation engineering in metallurgy shall be divided into the acceptance of unit（sub-unit）works，divisional（sub-divisional）project，constituent works and inspection lot.

2.3.2　Unit（sub-unit）works shall be defined as follows:

1　Electrical device installation works with an independent technological system and operational function is defined as a unit works（e.g.，power transmission line，etc.）.

2　For large-scale unit works，its electrical device installation work that can form independent operational functions can be divided into sub-unit works（e.g.，the cable network within a factory，etc.）.

2.3.3　Divisional（sub-divisional）works shall be defined as follows:

1　The division of divisional works may be made based on the technological system，zone，workshop，factory building，and design drawings，etc.

2　The divisional works with a large scale and a complicated technological system may be divided into subdivisional works in accordance with the rules for the division of divisional works.

2.3.4　Constituent works of electrical equipment installation engineering in metallurgy shall be named in accordance with Table 2.3.4.A constituent works may comprise one or several inspection lots，which can be divided in accordance with the electrical equipment system，stories of building，vertical and horizontal rows and columns of factory building，and construction drawing number etc.，as required by construction and quality control points and acceptance inspection.
