Section 13 Type Testing – General

13.1.1 New engine types or developments of existing types are to be subjected to an agreed programme of type testing to complement the design appraisal and review of documentation.

13.1.2 Requirements for type testing of engines are contained within the Lloyd’s Register Type Approval System, Test Specification No. 4 – Type Testing of Reciprocating Internal Combustion Engines and Associated Ancillary Equipment. In all cases the type test specification is to be agreed with LR.

13.1.3 Type testing specifications for other auxiliary systems are to be submitted for approval if they are to be tested separately from the engine.

13.1.4 Wherever practical, type tests are to be conducted with the engine control systems operational in the approved configuration, see Vol 2, Pt 2, Ch 1, 1.4 Submission requirements and Vol 2, Pt 2, Ch 1, 4.3 Control engineering systems 4.3.2. Configuration management documents that satisfy the requirements of ISO 10007 or an equivalent national or international standard, are to be reviewed at testing for validity and referenced in the type test report.

13.1.5 In addition to type testing against the requirements of Test Specification No. 4, engines may also be submitted for approval against recognised International or National Standards. Where this additional testing and appraisal is carried out satisfactorily, it will be stated on the Type Approval Certificate.

13.1.6 A type test carried out for a particular type of engine at any place of manufacture will be accepted for all engines of the same type built by the licensee or the licensor, subject to each place of manufacture being found to meet LR requirements for conformity of production.

13.2.1 Requirements for type testing of turbochargers are contained within the Lloyd’s Register Type Approval System, Test Specification No. 4 – Type Testing of Reciprocating Internal Combustion Engines and Associated Ancillary Equipment. In all cases the type test specification is to be agreed with LR.

13.3.1 Requirements for type testing of crankcase explosion relief valves are contained within the Lloyd’s Register Type Approval System, Type Testing of Test Specification No. 4 – Reciprocating Internal Combustion Engines and Associated Ancillary Equipment. In all cases the type test specification is to be agreed with LR.

13.3.2 The test specification is only applicable to explosion relief valves fitted with flame arresters. Where internal oil wetting of a flame arrester is a design feature of an explosion relief valve, alternative testing arrangements that demonstrate compliance with these requirements may be proposed by the manufacturer. The alternative testing arrangements are to be submitted to LR for appraisal.

13.4.1 Requirements for type testing of crankcase oil mist detection systems are contained within the Lloyd’s Register Type Approval System, Type Testing of Test Specification No. 4 – Reciprocating Internal Combustion Engines and Associated Ancillary Equipment. In all cases the type test specification is to be agreed with LR.

13.4.2 This test specification is also applicable to oil mist detection systems intended for gear cases.

13.4.3 The approval of one type of detection equipment may be used to qualify other devices having identical construction details. Proposals are to be submitted for consideration.

13.4.4 Acceptance of crankcase oil mist detection equipment is at the discretion of LR based on the appraisal of plans and particulars and the test house report of the results of type testing. See Vol 2, Pt 2, Ch 1, 1.4 Submission requirements 1.4.7.
