214 ppt 9 Soundness Testing and commissioning

Which type of joints should be checked to ensure they are tight before soundness testing?

• Soldered joints

• Compression joints

• Welded joints

• Glued joints

What should be checked to ensure that soldered joints are properly made?

• They are painted

• They are insulated

• They are visible

• They are secure

What should be attached after the system stands for 30 minutes?

• Pressure gauge

• Hydraulic test bucket

• Water pump

• Leak detector

What standard should the soundness testing conform to? (bonus point for correct answer)

• BSEN800

• BSEN806

• BSEN810

• BSEN820

If the example pressure given for a system is working at 3 bar, the pressure we should test to is _____

Which material would be pressurised for an hour at 1.5x working pressure, to be assessed for soundness ?

• Plastic pipes

• Copper and steel pipes

• Aluminum pipes

• PVC pipes

What is the first step in the soundness testing of a plastic pipe (polybutylene)?

• Pump the system to 1 bar.

• Walk around the system and check for leaks.

• Slowly fill the system with water.

• Increase pressure to 1.5 x working pressure.

What should be done after increasing the pressure to 1.5 x working pressure?

• Check for leaks

• Reduce pressure

• Check for pressure loss

• Fill the system with water

(a)   should be done immediately after filling the system with water.

• Increase pressure
• Walk around the system and check for leaks
• Reduce pressure
• Check for pressure loss

What is the second step in the soundness testing process?

• Charge system as required

• Watch the gauge

• Fill system

• Release pressure and remove
