Indian Standard SPECIFICATION FOR
WASTE PLUG AND ITS ACCESSORIES FOR SINKS AND WASH-BASINS
( First Revision )
0. FOREWORD
0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 31 December 1979, after the draft finalized by the Sanitary Appliances and Water Fittings Sectional Committee had been approved by the Civil Engineering Division Council.
0.2 This standard was first printed in 1965. As a result of experience gained during these years and the publication of the revised standards for wash-basins and sinks. it has been decided to revise this standard. Reference to the new standard ( IS : 7608-1975* ) as material for chain has been introduced.
0.3 In the formulation of this standard, due weightage has been given to international co-ordination amc;ng the standards and practices prevailing in diffcrcnt countries in addition to relating it to the practices in the field iv this country.
0.4 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 : 2-1960t The number of significant places retained in the rounded off values should be the same as that of the specified value in this standard.
1. SCOPE
1.1 This standard covers the requirements for materials, manufacture, construction, testing and finish of waste plug, chain and stay suitable for
*Specification for phosphor bronze wires ( for general engineering purposes ). tRulcs for rounding off numerical values ( r&sad ).

IS : 3311.1979
use in wash-basins and sinks complying with IS : 771 ( Part II )-1979*, 1s : 2556 ( Part IV )-1972t and IS : 2556 ( Part V )-19795.
1.1.1 The dimensions of the waste plug have been specified so as to suit waste fittings covered in IS : 2963-1979s.
2. MATERIALS, MANUFACTURE AND CONSTRUCTION
2.1 Waste Plug - The waste plu, u shall be made of rubber of hard and durable quality having sufficient chemical resistance to resist normal disinfectants used in cleaning wash-basins and sinks. It may also be made of any other equally suitable material. The depth and thickness of the plug shall be such as to provide and maintain required rigidity and watertightness.
2.1.1 Each waste plug shall have a loqse shackle which provides a suitable anchor for the plug chain. The shackle and other metal components, if any, of the plug shall be of brass or other equally suitable corrosion resistant material.
2.1.2 The shape and dimensions of plug shall be as shown in Fig. 1.
2.2 Chain - The chain shall be manufactured from phosphor bronze or brass wire conforming to IS : 7608-197511 and IS : 2704-19647 respectively or from any other equally suitable corrosion resistant material as agreed to between the manufacturer and the purchaser. Where it is made from bronze or brass wire, it shall have a minimum diameter of 1.80 mm with brazed oval links approximately 13 mm in length. The overall length of the chain ( excluding shackle ) shall be not less than 300 mm. One end of the chain shall be securely attached to the shackle of the waste plug and the other end to the shackle of the stay.
2.3 Stay - Chain stay shall be of bolt type or screw type as specified by the purchaser and shall be made of brass or any other equally suitable corrosion resistant material. The shank of the stays shall be fully threaded to the underside of the flange.
