Background

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 is substantively tightened. 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.

 

This seminar is tailor-made as a top-up workshop to understand how the quality control could be achieved to comply with the requirements as stipulated in the PNAP APP-37. The quality control supervisors would be TCP-T3 under the RSE stream and TCP-T1 under the RC stream respectively, who work in the glass façade field.

 

Seminar content

Ir. Dr. Yu will share his specialist experience in the structural design and use of glass to provide attendees with the following viewpoints regarding the structural use of glass, glass production and quality control, spontaneous breakage and the heat soak process:-

  1. The DO and DONT will be deliberated so as to enhance the effectiveness and efficiency when carrying out quality control on tempered glass;
  2. The documents and tests that need to be prepared and carried out by the manufacturer in the quality assurance;
  3. The techniques of calibrating the heat soak oven;
  4. The proper installation of the thermocouples on the glass surface;
  5. The rationale of installing an independent data logger by the TCP-T1.
