Water absorption en 99 iso 10545 3 astm c373 88 a tile s water absorption rate wa will tell you if the tile you re considering is the right tile to use in an outdoor or wet area.
Floor tile water absorption.
Water absorption is also directly related to the suitability for interior or exterior applications.
Tiles are classified according to water absorption percentages as follows.
Porcelain tiles have a far lower water absorption rate than glazed stoneware tiles for example.
This may seem like just another characteristic on the list of specifications but it is more than this.
The wa is determined by measuring the degree of internal porosity of the tile body and consists of boiling the tile in water and measuring its gain in weight.
Low water absorption enhances durability especially in circumstances where tiles may be subjected to heavy loads and or high levels of foot traffic.
Dense practically impervious tiles are highly unlikely to bend they are also highly resistant to liquid impregnation and subsequent staining consequently they are relatively easy to clean and.
All grouts except epoxies will allow some moisture absorption.
Absorbent value less than 0 5 e g.
For exterior applications the selected tiles should have a low water absorption rate especially in climates subjected to heavy rainfall and freezing and thawing cycles.
Absorbent value more than 3 e g.
Tiles can be differentiated according to their water absorption into 3 types as follow.
Objective determination of water absorption and bulk density of all ceramic tiles apparatus oven capable of maintaining temp of about 1100c balance accurate to 0 01 of the mass of test specimen water bath desiccators chamois leather wire basket preparation of test sample a test sample consists of 10 numbers of whole tiles.
Lowest absorption less than 0 5 water absorbed.
Suitable for all interior and exterior uses.
Absorbent value between 0 5 3 e g.
Water absorption astm c373 this is the measurement of density porosity and specific gravity as a tool for determining the degree of maturation of a tile or for determining structural properties that may be required for a given application.
For exterior applications the selected tiles must have a very low water absorption rate as close to an impervious rating as possible especially in climates subjected to rainfall freezing and thawing cycles.
Glazed tiles are resistant to water at the tile surface but susceptible at the edges.
To test this the fired tile is first weighed then it is boiled for five hours and left to sit in water for 24 hours.
The water absorption percentage reflects the density of the tile body.
In fact it tells us that the ceramic.
The water absorption rate is directly related with the suitability of the various types of tile for interior or exterior applications.
Homogeneous tile granite tile.
Only vitreous and impervious tiles should be used outdoors or in.
