47、ers or surveyors representative.The hose test shall consist of hosing the side scuttle by means of at least 12,5 mm nominal size hose held at a distance of not more than 1,5 m from the side scuttle and with a water pressure of a least 250 kPa.7.2 Shop testAn equivalent hydraulic test shall be carrie
48、d out by the manufacturer before despatch by means of batch tests (approximately 10 % of the delivery batch, with a minimum of two side scuttles).The side scuttle shall be tested by being subjected to the hydraulic pressures given in Table 13, under the following conditions:Procedure 1: With glass p
49、ane and open deadlight except for Type A, with diameters of 350 mm and 400 mm, where at a test pressure of 150 kPa the deadlight shall be closed.Procedure 2: Without glass pane and with closed deadlight.The rationale behind procedure 1 is that practice has shown that for normal side scuttles of Type A, with a diameter of 350 mm, 400 mm or 450 mm, when subjected to a test pressure of 150 kPa, the deflection between the fixed points is so heav
