ISO 7728:1985 is a standard that pertains to the classification and characteristics of typical horizontal joints between an external wall made of prefabricated ordinary concrete components and a concrete floor. One notable aspect of this standard is its focus on the watertightness of the joint. Although a specific method for determining watertightness has not been established, the standard acknowledges the significance of this property and offers a suggested solution based on experience and laboratory studies.

This standard is applicable to various types of buildings, whether public or private, and includes those used for residential purposes, offices, educational facilities, and hospitals. The aim is to ensure that the horizontal joints between the external walls and concrete floors in these structures meet certain standards in terms of properties and characteristics.

Overall, ISO 7728:1985 provides guidelines for the classification and evaluation of the horizontal joints to maintain the desired level of watertightness in typical structures. It emphasizes the importance of this property and offers a solution that has been found to be adequate under normal conditions. The standard seeks to promote uniformity and reliability in the construction industry, particularly in relation to the interaction between prefabricated concrete components and concrete floors.
