IS 13630 (Part 7) : 2006 ( ) Indian Standard CERAMIC TILES -- METHODS OF TEST, SAMPLING AND BASIS FOR ACCEPTANCE ( First Revision) ICS 91.100.23 © BIS 2006 BUREAU OF INDIAN STANDARDS MANAK BHAVAN , 9 BAHADUR SHAH ZAFAR MARG NEW DELHI 110002 August 2006 Price Group 1 Flooring, WallFinishingand RoofingSectionalCommittee, CED S FOREWORD This Indian Standard (Parts 1 to 15) (First Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Flooring, Wall Finishing and RoofingSectionalCommittee had been approved by the Civil Engineering DivisionCouncil. This standard was first publishedin variousparts in 1992-93. This is the first revision;havingall parts combined in one publication, of the standard in whichthe following major changeshave been incorporated: a) As per the decisiontaken in the last meeting, the requirements of all the parts have been includedin one volume and the revised standardhas been brought in line with ISO 10545 (various parts). b) The requirements for determination of bulk density have been added in Part 2 and a few changes have . been made in the requirements for determination of water absorption. c) A few modifications have also been made in Part 3. d) Requirements for determination of breakingstrengthhave also been added in Part 6. e) Requirements for determination ofglazingresistance tests have also been modified in Part 9. t) A new test for determination of impactresistance by measurement of co-efficient of restitutionhas been added as Part 14. g) IS 13711 : 1993 'Samplingand basisfor acceptance'has beenamalgamated with Part 15 ofthis standard. In formulation ofthis standard considerable assistance have been derived from the following standards: ISO 10545-1 : 1995 Ceramictiles - Part 1 : Sampling and basis for acceptance ISO 10545-2 : 1995 Ceramictiles - Part 2 : Determination of dimensions and surface quality ISO 10545-3 : 1995 Ceramictiles - Part 3 : Detennination of waterabsorption, apparentporosity, apparent relative density and bulk density ISO 10545-4 : 2004 Ceramictiles - Part 4 : Determination of modulus of rupture and breakingstrength ISO 10545-5 : 1996 Ceramic tiles- Part 5 : Determination of impact resistance bymeasurement of coefficient of restitution ISO 10545-6 : 1995 Ceramictiles - Part 6 : Determination of resistanceto deep abrasionfor unglazedtiles ISO 10545-7 : 1996 Ceramictiles - Part 7 : Determination of resistance to surfaceabrasionfor glazed tiles ISO 10545-8 : 1994 Ceramictiles - Part 8 : Determination of linear thermalexpansion ISO 10545-9 : 2004 Ceramictiles - Part 9 : Determination of resistance to thermalshock ISO 10545-10 : 1995 Ceramictiles - Part 10 : Detennination of moistureexpansion ISO 10545-11 : 1994 Ceramictiles - Part 11 : Determination of crazing resistancefor glazed tiles ISO 10545·12 : 1995Ceramictiles - Part 12 : Determination offtost resistance ISO 10545-13 : 1995 Ceramictiles - Part 13 : Determination ofchemicalresistance ISO 10545-14 : I99S Ceramictiles - Part 14 : Determination of resistanceto stains ISO 13006 : 1998 Ceramictiles - Definitions, classification, characteristics and marking For the purpose of deciding whethera particularrequirement of this standard is complied with, the fmal value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2.: 1960 'Rules for roundingoff numerical values (revised)'. The numberofsignificantplaces retained in the rounded off value should be the same as that of the specifiedvalue in this standard. · IS 13630 (part 7) : 2006 Indian Standard CERAMIC TILES - METHODS OF TEST, SAMPLING AND BASIS FOR ACCEPTANCE PART 7 DETERMINATION OF CHEMICAL RESISTANCE UNGLAZED nLES ( First Revision) 1 SCOPE 4.2 SwlmDlIDI Pool Salts a) Sodium hypochlorite solution 20 mg/l, prepared from technical grade hypochlorite with about 13 percent active chlorine, and b) Copper sulphate solution, 20 mg/l. 4.3 Aeld.
