BS EN ISO 6428:1999

1   Scope and field of application This International Standard specifies the requirements to be observed when executing original technical drawings and other drawing office documents which are to be microcopied. These requirements will provide for high quality microforms with which legible enlargement copies can be made. However, the application of these rules is also very beneficial for other methods of reproduction and it is therefore recommended that all drawing office documents be executed in accordance with this International Standard, thereby being available for microcopying at a future date.
