MIL-M-23530A

Abstract

This specification covers the requirements for the development and presentation of mock-ups of main and auxiliary shipboard machinery spaces and the requirements for mock-up booklet and other supporting documentation. Mock-ups will normally be required for spaces such as the engine room, fire room, auxiliary spaces, fairwater, uptakes, fan rooms, countermeasure launcher room, torpedo room, or other spaces or stations, as specified (see <a>6.2.1</a>). <br>Mock-ups of machinery spaces and equipment components shall be of the types and classes specified in <a>1.2.1</a> and <a>1.2.2</a>, as specified (see <a>6.2.1</a>). <br>Machinery space mock-ups shall be of the following types: <br>Type I - Reduced scale. <br>Type II - Full scale. <br>Equipment components and systems shall be of the following classes: </span><pre> Class 1 - Exact reproduction of shape and external dimensions. Class 2 - Reproduction of general shape and major external dimensions in sufficient detail to permit easy identification and to ensure arrangements compat- ibility with all adjacent equipment, components, and systems. Class 3 - Reproduction to show volume occupied by an item by use of blocks, other simple shapes, or combinations of shapes.</pre> <br> <br><b><u>Intended Use:</u></b> Mock-ups are intended to be used as a tool to assist in the development of the construction drawings during the detail design of a new ship or class of ships or during major overhauls. Mock-ups also function as an aid in development of improved ship production techniques. <br>
