Excellent: in qualified on the basis of the uniform slot, flat, horizontal joints staggered. Test methods of observation and inspection.

Section 5.3.6 loose materials and soft material insulation should satisfy the following requirements:

Qualified: bulk material bulk density meet design requirements, laying down basic uniform; tight soft material flow, seamless; wrap firmly.

Excellent: in qualified on the basis of uniform, bandaging, laying a solid, flat. Test methods of observation and inspection.

No. 5.3.7 section moisture-proof layer should satisfy the following requirements:

Qualified: close securely to paste in the insulation, a joint estuary towards the low end. Width conform to the specifications for the construction of overlap, the closure of good, no crack.

Excellent: in qualifying lap, on the basis of uniform and tidy appearance. Test methods of observation and inspection.

Section 5.3.8 article smearing materials protection layer should satisfy the following requirements：

Qualified: batching accuracy, basic smooth riding surface with no visible cracks.

Excellent: batching accuracy, smooth surface smoothness, no crack. Test methods of observation and inspection.

Section 5.3.9 of thin metal plate protection layer should satisfy the following requirements:

Qualified: Lap downstream direction, and the width of the appropriate interface formation, fastening:

Excellent: in qualifying lap, on the basis of the uniform, consistent, pleasing in appearance. Test methods of observation and ruler.

(Ⅲ) tolerance project

Section 5.3.10 smoothness of insulation, heat insulation layer thickness allowable deviation and testing methods should be consistent with the requirements of the table 5.3.10.

Insulation-insulating layer thickness, flatness of permissible deviations and inspection methods table 5.3.10
The project allows deviation (mm) test method 1 insulation layer surface roughness rolls, shell and smudge 5 used 1m ruler and wedge feeler gauge check bulk material or soft materials 10 2 insulation thickness + 0.10 δ
-0.05 δ steel needle into the insulation and the ruler check
Note; δ insulation thickness.

Appendix a ventilation, air conditioning, clean the system of measurement and adjustment

Ventilation, air conditioning works by measuring: debugging in order to discover the existence of the substantive issues, ventilation, air conditioning construction finished in addition to Visual inspection system should also be conducted outside of determination, debugging, its main elements are as follows:

1. determination of total system air flow, pressure and wind speed, measured total air volume value compared with the design values, such as the deviation is greater than 10%, should be analyzed to find out why;

Second, the outlet of the air flow in the system and must be adjusted to achieve balance, the outlet air flow measured values and design value deviation should not be greater than 15%;

3. wind pipes system leakage rate should meet the design requirements or should not be greater than 10%;

4. clean system HEPA filter and HEPA filter and frame connection of seepage rates must meet the design requirements.

5. determination of engineering needs fashion should AHU dew point temperature, indoor air temperature and indoor temperature and humidity.

Appendix 4 of this standard word description

First, in order to facilitate the implementation of this standard provisions distinguish between, on the strict wording of the different levels are described below:

1, that is very strict and non-do not use the term of: positive "must", "non-negative terms."

2, indicates that, under normal circumstances should do: positive words use "should", "negative words used and should not be" or "no".

3. Select allow slightly, in conditions permit first should do: positive words use "should" or "may", "should not be used as negative words."

Second, the provisions specified by other standards, specifications, the wording "should be consistent with the ... Provisions ". Non-must have specified standards, specifications or other requirements, the wording is "you can reference ...".
