• Amended announcement for the ‘Fire damper standard’

6. Amendment of fire resistance tests for ventilation ducts

a. Code amendment
In the amended code, information about the installation and the application of ventilation ducts where fireproof dampers cannot be installed is provided. Hence, designers or customers can have an option to chose the type of ducts (ducts with fireproof dampers or ducts without fireproof dampers) on their purpose in practice. The way of testing the ducts without fireproof dampers is a new methodology that has not been established in Korea before. By establishing this code, it is possible to evaluate the performance of fire resistance ducts. The amendment is made in the Korean regulations below.

• Regulation for the evacuation & fireproof structures of buildings
• KS F 2841 (Fire resistance tests for ventilating ducts)

b. Methodology amendment
Current methodology for testing fire resistance performance of fireproof ducts follows KS F 2841, which was made based on ISO 6944 established in 1985. However, recently, ISO 6944 was abolished. Instead, ISO 6944 is divided into two codes: one is ISO 6944-1 (ventilation ducts), and the other is ISO 6944-2 (kitchen ducts). Hence, to reflect this recent amendment of ISO, it is necessary to revise KS F 2841. For closely follow the current ISO code of fireproof ducts, the methodology and entire content in KS F 2841 were revised, and a title was also changed to match up with ISO code as shown below.

• KS F ISO 6944-1 Fire containment-Elements of building construction
- Part 1: Ventilation ducts

7. Amendment of fire stop system

a. Managing the compressing density of the fireproof material at the curtain wall linear joint
The fireproof material of the linear joint fire stop system at the curtain wall structure has much influence on the fireproof performance. But, it is difficult to secure the fireproof performance of the curtain wall structure because the current regulation does not reflect it, so the related regulate is amended to check whether the fireproof material is compressed or not.

• amendment of the standard for approving and managing the fire stop system

b. Differentiating the fireproof performance on the penetrating equipment
The current regulation too highly controls the fireproof performance of all penetrating equipments uniformly, but it is amended to classify by the insulating(Class T) performance and the smoke-blocking (Class F) performance according to the building type, the importance and the penetrating material just like the foreign cases.

• amendment of the detailed operating guide on the fire stop system

c. Correct fireproof test on Curtain wall linear joint
The investigation on the damage caused by the fire reports many fire spread cases due to the bad spandrel panel. But, the current regulation provides to check only the performance of the fireproof at the linear joint, so it is very highly possible for the fire to spread. So, the sample making, the test method, the testing structure, the test procedure and the determinating standard are newly established.

• amendment of the detailed operating guide on the fire stop system

d. Movement test on the fireproof material at the linear joint
The adhesive strength of the linear joint of the high building on the fireproof material and the structural element may be reduced by earthquake, wind, heat or others after the installation, which may greatly influence the fireproof performance. The related regulation is amended to meet the domestic situation by reviewing the contents not meeting to the ISO standard over the added contents of the movement test(not included at the current detailed domestic guide) and the basic test.

• amendment of the detailed operating guide on the fire stop system

e. Limiting the pipe size of the penetrating equipment and the mizimum size of the penetrating duct
The current regulation does not provide the concrete contents for the penetrating pipe and duct size of the fire stop system. So, the related regulation is amended. First, the maximum size of the penetrating material is Φ400 mm by reflecting the domestic sitxiation, and the larger one may be used with no separate performance test. Also, the maximum size of the penetrating duct is 1000 mmx250 mm (wall) for the horizontal penetrating one while 1000 mmx500 mm (floor) for the vertical penetrating one, and the larger one may be used with no separate performance test.

• amendment of the detailed operating guide on the fire stop system

f. Preparing the 3-hour fireproof performance standard for the wall supporting structure
The current regulation requires the 2-hour of the fireproof performance for the wall supporting structure, but its importance is getting increased. So, it is amended to secure the 3-hour of the fireproof performance for the related system.

• amendment of the detailed operating guide on the fire stop system

8. Other amendments
