BS 5385-4:2015 pdf download – Wall and floor tiling – Part 4: Design and installation of ceramic and mosaic tiling in specific conditions – Code of practice
This part of BS 5385 gives recommendations for the design considerations andinstalilation of ceramic wall and floor tiling and mosaics in situations where there are specific functional, e.g. sterile conditions, or environmental requirements, e.g. wet areas, and conditions that are potentially detrimental,e.g. chemical attack, to either or both the installation or the background.Recommendations are given for the choice of materials,application practicesand, where appropriate, for the design of backgrounds and structural bases.This part of BS 5385 augments the recommendations given in BS 5385-1,BS 5385-2 and BS 5385-3.
NOTE BS 5385-1,BS 5385-2 and BS 5385-3 give recommendations for internal andexternal, wall and floor tiling and mosaics for exchanging information, time schedules, suitable materials, tile backgrounds and bases and their preparation,cement and sand rendering, movement joints, bedding methods for tiles andmosaics, grouting, protection, cleaning and maintenance.

3Terms and definitions
For the purposes of this part of BS 5385, the terms and definitions given inBS 5385-1,BS 5385-2,BS 5385-3,BS 6100-6 and BS EN 14411 and the followingapply.
3.1salt water
all types of saline water such as medicinal spa water, used in swimming andhydrotherapy pools, and seawater
3.2chemical attack
that which occurs when certain materials in tile installations are affected bychemical reaction
NOTE For example, when cementitious bedding and joint filling materials areattacked in acidic conditions.
3.3mildly corrosive situations..
situations in which the corrosive substance is of low concentration, or is onlymildly aggressive by nature, or is promptly removed after spillage
3.4highly corrosive situations
situations in which the corrosive substance is highly aggressive, especially if it islikely to remain in contact with the tiling for long periods
The conditions covered in this part of BS 5385 fall into two groups:a)conditions to be resisted (see Clause 5 to Clause 10):
movement (see Clause 5);
traffic and load conditions (see Clause 6);wet and damp conditions (see Clause 7);chemical attack (see Clause 8);
thermal effects (climatic and environmental)(see Clause 9);contamination from radioactivity (see Clause 10).
b)Conditions to be achieved (see Clause 11 to Clause 14):sterile conditions (see Clause 11);
thermal insulation (see Clause 12);sound insulation (see Clause 13);anti-static conditions (see Clause 14).
For situations where several conditions are present the design specificationshould be directed towards achieving the most important function required ofthe system. In some cases a compromise solution might be found for meetingconflicting needs, but this should not be undertaken if its adoption is likely toplace the durability of the installation at risk.
