Section 1 General

101. Application

1. The requirements in this chapter apply to FRP materials, FRP and metallic materials used for FRP ships' building or repairs.

2. Other materials not prescribed or not matched in this chapter may be used in specially approved cases according to designs. In this case the specified materials' details shall be submitted and ap- proved by the Society.

102. Approval and Manufacturing Control

1. Approval

(1) The workshop which FRP ship applied for survey during construction are moulded shall submit details about moulded workshop facility and FRP materials' storage facility, etc. and be subject to Manufacturing Method Approval in accordance with the Guidance relating to the Rules.

【See Guidance】

(2) FRP materials (fibre reinforcements, resins and core, etc.) used for FRP ship applied for survey during construction are appropriate to Pt 2 of Rule for the Classification of Steel Ships and are subject to Type Approval in accordance with the Guidance relating to the Rules.

【See Guidance】

(3) The metallic materials (rolled steel, steel pipe, cast steel, forged steel, copper alloy and alumi- num alloy, etc.) used for FRP ship applied for survey during construction are in accordance with the requirements in Pt 2 of Rules for the Classification of Steel Ships.

2. Manufacturing control

(1) It is the manufacturer's responsibility to assure that effective process and production controls in operation are adhered to within the manufacturing specifications.

(2) Where control imperfection inducing possible inferior quality of product occurs, the manufacturer

is to identify the cause and establish a countermeasure to prevent its recurrence. Also, the com- plete investigation report is to be submitted to the Surveyor.

(3) For further use, each product affected by previous (2) is to be tested to the Surveyor's

satisfaction. The frequency of testing for subsequent products offered may be increased to gain confidence in the quality at the discretion of the Society.

103. Materials for Constructions

1. Fibre reinforcements, resins and cores for sandwich constructions used for FRP materials are in ac- cordance with requirements of each clause in 102. 1 (2) and Ch 3, Sec 2.

2. FRP used for FRP ship constructions are in accordance with requirements of Ch 3, Sec 3.

3. Materials (plywoods and timbers, etc.) used for constructions except FRP constructions are in ac- cordance with requirements of each clause in Ch 3, Sec 2.

4. Steel plates, angles, rivets and welding rods are to be in accordance with Pt 2 of Rules for the

Classification of Steel Ships and steel equipment are to be

protected by plating or other proper

methods. Further, the surfaces of steel equipment covered by FRP are to be cleaned perfectly in order not to be included rust, oil or foreign substances.
