SPECIFICATION FOR BIFURCATED RIVETS FOR GENERAL PURPOSES

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Institution on 17 January 1967, after the draft finalized by the Screw Threads and Fasteners Sectional Committee had been approved by the Mechanical Engineering Division Council.

0.2 Bifurcated rivets are extensively used in large quaritities to fasten many types of materials such as wood, plastics and leather. The bifurcation is formed by sawing or punching. out the slot from a solid rivet.

0.3 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, shall be rounded off in akcordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

13 This standard prescribes the requirements for two types of bifurcated rivets given below:

a) Oval-head bifurcated rivet, and

b) 120”-countersunk head bifurcated rivet.

2. MATERIAL

2.1 The material for steel bifurcated rivets shall conform to Cl5 of Schedule II of IS : 1570-1961 t. The percentage each of sulphur and phosphorus in the- steel shall not exceed O-05.

2.1.1 Rivets made from steel may be electroplated. 2.2 The material for aluminium and aluminium alloy bifurcated rivets shall conform to IS : 740-1966$.

2.3 The material for brass bifurcated rivets shall conform to IS : 320-19620.

IS : 3974 - 1967

3. DIMENSIONS

3.1 ‘l-he dimensions for bifurcated rivets shall be as given in Tables I and 2.

4. WORKMANSHIP AND FINISH

5.1.2 A 120”-countersunk head bifurcated rivet of nominal size 3 mm, length 10 mm, conforming to this standard and made from aluminium shall be designated as:

120” CSK Hd Bifurcated Rivet 3 x 10 IS : 3974 Aluminium.

6. PRESERVATION AND PACKING

6.1 Preservation - Unless the purchaser has specified a particular treat- ment at the time of enquiry or placing the order, the bifurcated rivets shall be supplied in a well cleaned condition and suitably protected against corrosion.

6.2 Packing - The bifurcated rivets shall be wrapped in water-proof paper packets or cartons, the weight of the rivets in the packet or carton being 0.5 kg. Fifty such packets or cartons shall be suitably .packed in wooden cases. Each packet, carton or wooden case shall contain rivets of one size and type only.

7. SAMPLING

7.1 For the purpose of conducting tests for conformity of the bifurcated rivets to this standard, the sampling of bifurcated rivets shall be in accord- ance with IS : 2614-1964+.

8. MARKING
