4.1 This practice is for use by designers and specifiers, regulatory agencies, owners, and inspection organizations who are involved in the rehabilitation of sewer service laterals and its connection to the main through the use of a resin-impregnated tube installed within an existing sewer lateral. As for any practice, modifications may be required for specific job conditions.1.1 This practice covers requirements and test methods for the reconstruction of a sewer service lateral pipe having an inner diameter of 3 to 12 in. (7.6 to 30.5 cm) and its connection to the main pipe having an inner diameter of 6 to 24 in. (15.2 to 61.0 cm) and up the lateral a maximum of 150 ft (46 m) without excavation. The lateral pipe is accessed remotely from the main pipe and from a lateral access point. This will be accomplished by the installation of a resin impregnated one-piece main and lateral cured-in-place lining (MLCIPL) by means of air inflation and inversion. The MLCIPL is pressed against the host pipe by pressurizing a bladder and is held in place until the thermoset resins have cured. When cured, the MLCIPL shall be a continuous, one piece, tight fitting, corrosion resistant lining extending over a predetermined length of the lateral pipe and the adjacent section of the main pipe, providing a verifiable non-leaking structural connection and seal.1.2 The values stated in inch-pound units are to be regarded as standard.

4.1 Comparison of brake horsepower developed and of specific fuel consumption rates from engine to engine may be made by use of data based upon a standard for composition of an engine assembly.4.2 The purchaser of the engine assembly will be fully advised of the minimum scope of assembly which the purchaser may rightfully expect to be encompassed by a response to a request for quotation and to be delivered in response to a purchase order unless the engine builder in the proposal or in the offer to sell has clearly advised otherwise.4.3 It will be made apparent to the purchaser that additional auxiliary and accessory equipment will be needed to supplement the defined engine assembly when full consideration is given to the application of the engine assembly as a prime mover in a specific vessel.1.1 This guide covers performance and minimum scope of assembly of all medium speed marine diesel engines intended for main propulsion of single or multiple screw propelled marine vessels or for vessels using other than screw propeller-type main propulsion.1.2 This guide is intended to supplement the regulations of legally constituted regulating authorities. In the event of any conflict, which may become apparent after publication of this guide, with such legally constituted regulations, the latter shall take precedence, as may be applicable within the jurisdiction of such authorities and specific to each case, unless such latter regulations are formally waived by proper cognizant authority.1.3 This guide is not intended to relieve the purchaser of the obligation fully to advise the engine builder of all of the purchaser’s unique operational considerations to allow those considerations to be satisfied.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
