Building Standards Ltd. (BSL) offers tests for performance of tiles used for different applications.

List of tests for tiles.

• 1.    Physical properties
  • I. Water Absorption (by weight)
  • II. Breaking Strength
  • III. Modulus of Rupture
  • IV. Abrasion Resistance (volume shrinkage)
• 2.    Chemical properties
  • I. Resistance to Low Concentration of Acids And Alkalis
  • II. Resistance to High Concentration of Acids And Alkalis
  • III. Resistance to Household Chemicals
  • IV. Resistance to Swimming Pool Salt
  • V. Resistance to Concentrated Nitric Acid & Sulphuric Acid
