The course consists of 2-half day events.

Breakage of tempered glass may be attributed to three primary causes, i.e. design fault, bad workmanship and spontaneous breakage respectively. Amongst these causes, the spontaneous breakage due to nickel sulphide (NiS) inclusions is reckoned as the most commonest cause that is directly related to the quality assurance and control during the course of manufacturing tempered glass.

In the advent of a series of incidents on glass breakage, the control on the tempered glass has been tightened up. As stipulated in the PNAP APP-37 on Curtain Wall, Window and Window Wall Systems, the following documents are required to be submitted: -

1. Quality Assurance Scheme by the glass manufacturer prior to the consent application of the glass works;
2. Quality Supervision Plan by the RSE prior to the consent application of the glass works;
3. Heat Soak Process Compliance Report by the RSE prior to the application of an occupation permit; and
4. Quality Supervision Report by the RSE prior to the application of an occupation permit.

The captioned seminar focus on the quality control of tempered glass and good practice of heat soak process.  The rationale of requirements for temperature measure, calibration and supervision in heat soak process as stipulated in PNAP APP-37 will be discussed in the seminar.  New calibration method and latest requirement of heat soak process as in BS EN 14179-1: 2016 will be introduced.  The DO and DON’T’S will be deliberated so as to enhance the effectiveness and efficiency when carrying out building control on tempered glass. 

The documents and tests that need to be prepared and carried out by the manufacturer in the quality assurance would be cited.  The techniques of calibrating the heat soak oven, the proper installation of the data logger with thermocouples on the glass surface and the rationale of installing an independent data logger by the TCP-T1 would be mentioned in great details.
