Indian StandardSPECIFICATION FOR

CAST COPPER ALLOYS TRAPSPART I ,p' AND 'S' TRAPS

o. FOREWORD

0.1 This.Indian Standard ( Part I ) was adopted by the Indian StandardsInstitution on 13 August 1969, alter the draft finalized by the SanitaryAppliances and Water Fittings Sectional Committee had been approved bythe Civil Engineering DivisionCouncil.8.2 This standard ( Part I ) coven the requirements for IP , and IS' trapsmade of copper alloys and their associate component parts for use withwaste appliances, such as wash basins, sinks and bath tubs. The secondpart of the standard, under preparation, will cover the requirements forbottle ~raps made of cast copper alloys.0.3 While preparing this standard the Sectional Committee was aware ofthe acute scarcity of non-ferrous metals like copper, tin and nickel in thecountry and the need for conserving the use of the same. However, notingthe present manufacturing practice in the country only cast copper alloytraps have been covered in the standard and work is in progress coveringthe use of other materials available from indigenous sources, such as,plastics and ferrous metals; further, only brass castings with reducedcopper contents have been specified in this standard.0•• It is a general practice to provide internal threads on the inlet of traps;and to facilitate connections With waste bodies, use of inlet tail pipe andcoupling nut has been specified. External threads are provided on theoutlet in case of screwed outlet traps thr connections to waste pipes.0.5 Straight inlet tail pipes are specified to be threaded with metric screwthreads conforming to the basic profile of ISO metric screw threads. SizesM33 x l, M42 X I and M52 X 1are specified for nominal sizes 32 rnm, 40 mmand 50 mm although pitch one not very common with diameters 33, 42and 52 but it is essential to have finer threads on the tail pipes and inlet oftraps and next higher pitch of 1'5 mm is not good enough for the purpose[s« IS: 4218 (Part I) -1~7 to IS: 4218 (Part VI) .1967· ].

This hu been met by deriving assistance tomB.S.II84--1961 •Specification (or copper and copper alloy traps and wutea'.0.8 For the purpose ofdeciding whether a particular requirement of thisstandard iscomplied with, thefinal value, obeerved or calculated, expressingthe result of a test or analysis, shall be rounded oft' in accordance wkhIS : 2-1960*. The number ofsignificant places retained in the rounded oft'value should be the same u that of the spCcified value in this standard.

1.8COPE1.1 This standard (Part I) covers copper alloy t:aat traps • P' and •S 'types and their associated components of nominal sizes 32 mm, 40 mmand 50 mm for use in wuh buins, sinks, bath tubs and similar wasteappliances.

2. TERMINOLOGY

2.0 For the purpose of this standard, the following definitions shall apply.2.1 Trap - A tabular device to prevent the passage of foul gases bymeans ofa water s~a1 from a waste pipe into a building.2.2 'P' Trap - A trap in which when the inlet legis vertical, the outletleg is inclined below the horizontal within the limits specified in thisstandard.2.3 •S ' Trap - A trap inwhich_the outlet legisparallel with theinlet leg.2.4 Water Sea1- The depth of _ter which shall be removed from a fullycharged trap before gases at atmospheric pressure may pasl from the wastepipe through the trap into a building.2.5 A..odatecl CompoaeDt. - These shall mean the tailpipes, couplingnuts, blank nuts, clean out plugs, removable caps and waahen.

3. NOMINAL SIZES3.1 The trap shall be manufactured in the following nominal sizes:

32 mm, 40 mm and 50 DUD.

4. MATERIALS4.1 CudD,. - The castings shall be of brass withcopper content not lessthan 56 percent.

'Rulesfor rouad1ns ofnurntrical valuea ("lIiud).

N'OTI- Caslings made from lhe brlJl scrap materiab may be URd provided tberOPPfr content it not Ie.. than the value given in 4.2. •

4.2 Preallap - Pressings where used for associated components shall beofforgeable brass with the following composition:

Min Mu56'5 60'01'0 2'5

NOTE - Total impurities not more than 0'75percent.

4.3 The washers where supplied shall be of compressed fibre conforming toGrade C of IS : 2712·1965t or equally suitable rubber material.

5. WORKMANSHIP AND FINISH

5.1 Casting shall be sound in all respects, free from blow holes, laps andsand pittings. Both the external and internal surface shall be dean,smooth and free from sand. No casting shall be phj.gged, stopped orpatched.

5.2 The external surface of traps and Ulqciated components shall have oneof the following finishes:

a) Self-colour, free from grease and tool marks;b) Polished; andc) Nickel or chromium plated.

6. DESIGN AND CON8TRUClION

6.1 Typical illustration. of traps are shown in Tables I to 8.

NOTE - The filUre~ arcintended to show mainfcatutelor the partsonly and areDotintended to limit the desigD aadlbapes ofcomponent parts.

6.2 Ialet - Inlet of every trapshall have internal threads conforming tothe basic profile of ISO }petrie screw threads (IS: 1362.1962*) and .hallbe provided witha tail pipe and a coupling n!Jt. The tail pipe shall bescrewed~n to the inlet wjth a minimum engagement of8 mm and securedin position bysoldering. ,
