Signal flags according to the International Radiotelegraph Conference in Washington in 1930.

During WWI, the international signal book from 1897 was found not to work properly between ships of different nationalities. It was therefore decided to thoroughly revise this book.

Numeral pendants have been introduced and substitutes. This book has been the international standard since 1930. They serve as a means of communication between ships and from ships to the authorities ashore.
