3 IS 2666 ( Part 6 ) : 1894 ( Reaffirmed 2004 ) Indian Standard VITREOUS SANITARY APPLIANCES ( VITREOUS CHINA ) - SPECIFICATION PART 5 SPECIFIC REQUIREMENTS OF LABORATORY SINKS ( Third Revision ) 1996 First Reprint FEBRUARY UDC 696.142 : 666.596 : 727.57 0 BIS 1994 BUREAU OF INDIAN STANDARDS SHAH ZAFAR MARG Price Group 3 MANAIS BHAVAN, 9 BAHADUR August 1994 NEW DELHI 110002 Sanitary Appliances and Water Fittings Sectional Committee, CED 3 FOREWORD This Indian Standard ( Third Revision ) was adopted by the Bureau of Indian Standards, after the draft finalized by the Sanitary Appliances and Water Fittings Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1963 and the first and second revisions were issued in 1967 and in 1979 respectively. In this revision changes found necessary in the light of the comments made by users and improvements made by the vitreous sanitaryware industry have been incorporated. This standard contains clause 4.1.1 which calls for an agreement between the purchaser and the supplier. The waste fitting made of vitreous china has been deleted from this standard as neither it is manufactured nor it is normally used. In the formulation of this standard due weightage has been given to international co-ord,mation among the standards and practices prevailing in different countries in addition to the practices m the field in this country. Dimensions of waste hole have been aligned with EN 32 `Wallhung Wash Basins: Connecting Dimensions'; issued by European Committee for Standardization. The composition of the technical committees responsible in the formulation of this standard is given in Annex A. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2 : 1960 `Rules for rounding off numerical values ( revised)`. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
