SOLAS II-2 / Reg. 9.3
3 Penetration in fire -resisting divisions and prevention of heat transmission
3.1 Where "A" class divisions are penetrated, such penetrations shall be tested in accordance with the Fire Test Procedures Code, subject to the provisions of paragraph 4.1.1.5. In the case of ventilation ducts, paragraphs 7.1.2 and 7.3.1 apply. However, where a pipe penetration is made of steel or equivalent material having a thickness of 3mm or greater and a length of not less than 900 mm (preferably 450 mm on each side of the division), and no openings, testing is not required. Such penetrations shall be suitably insulated by extension of the insulation at the same level of the division.
我的理解是你用的是红色字体的这种做法,但需经过试验达到A60要求才能用的;而该验船师建议的是蓝色字体的做法,不需要进行试验的。本人倾向于后一种做法。 |
