* Classification of glazed floor tiles to their abrasion resistance (as per ISO 130006: 1998):

  • Class I: Floor walked on mainly by shoes with soft soles. Resistance to surface abrasion- failure not visible at 500 times.
  • Class II: Floor walked on by normal foot wares with occasional small amount of scratching dirt. Resistance to surface abrasion-failure not visible at 1000 times.
  • Class III: Floor walked on by normal footwear with more often small amount of scratching dirt. Resistance to surface abrasion- failure not visible at 1500 times.
  • Class IV: Floor walked on by regular traffic with some abrasive dirt. Resistance to surface abrasion failure not visible at 5000 times.

** Classification of unglazed floor tiles according to their abrasion resistance (as per Test Method D in SS 301):

  • Light wear: floor walked on by normal shoes and subjected to infrequent traffic with weak abrasion. Resistance to deep abrasion- average volume of material removed not exceed 400.
  • Medium wear: Floor walked on by normal shoes and subjected to frequent traffic with medium abrasion. Resistance to deep abrasion- average volume of material removed not exceed 205
  • Floor subjected to heavy traffic with strong abrasion: Resistance to deep abrasion- average volume of material removed not exceed 160.

Water Absorption

0.04-0.5%

Water Absorption (E) measured in accordance with ISO 10454-3 or SS 483:2000

  • Tiles of low water absorption (Group I), E =< 3%, further divided as follows for dry-pressed tiles:
  1. Group BIa: E =< 0.5%
  2. Group Bib: 0.5% =< E =< 3%
  • Tiles of medium water absorption (Group II), 3% < E =< 10%, further divided as follows for extruded tiles;
  1. Group AIIa, Part 1 and 2: 3% < E =< 6%,
  2. Group AIIb 6% =< E =< 10%·
  • Tiles of high water absorption (Group III), E > 10%

Chemical Resistance (complies with EN 106)

Based on ISO 10545-13 classification:

Household chemical:

  • Class UA: No visible effect
  • Class UB: No visible effect on cut sides
  • Class UC: Visible effect on cut sides; non-cut sides & non proper surface.

High concentration:

  • Class UHA: No visible
  • Class UHB No visible effect on cut sides
  • Class UHC: Visible effect on cut sides; non-cut sides & non proper surface.

Thermal Shock Resistance

Homogenous tile is thermal shock resistance (complies with EN 104).
