FOREWORD

This Indian Standard was adopted’ by the Bureau of Indian Standards, after the draft finalized hy the Shipbuilding Sectional Committee had been approved by the Transport Engineering Division Council.

This standard was originally issued in 1967 and subsequently revised in 1975. The major changes in this revision relate to redrafting of terminology in some cases, inclusion of extra special steel in materials used for the manufacture of Grade 3 chains, change of mechanical properties of materials and heat treatment of chains. Another important change allows smaller lengths of anchor chains to be supplied to meet the customers or equivalent number requirements in addition to standard length of 27.5 m. In testing of material, impact test has been included for grade 3 chain cables and the require- ment of bend test has been deleted. In order to bring the nominal diameters in line with IS0 1704 : 1991, three nominal diameters, namely, 83, 85 and 112 millimetre have been deleted and two new nomi- nal diameters, namely, 157 and 162 millimetre have been included.

This standard is one of a series of Indian Standards on anchor chains. Other standards to this series are:

IS 4690 : 1968 Mooring buoy shackles

IS 4692 : 1977 Electrically welded studless (.first revision )

link anchor chains and connecting shackles

IS 5859 : 1970 Tools for handling of anchor chains and attachments

The ships’ anchor chains are governed by the statutory provisions of the Anchors and Chain Cables Act which includes proof load but does not include detailed dimensions of the links and shackles. This standard is, therefore, complementary to the Anchors and Chain Cables Act which implies that the statutory proof loads are duly applied.

It is important to note that all dimensions specified in this standard are the dimensions of the various parts of anchor chains after the cables and cables and shackles have been subjected to the statutory proof loads which they have satisfactorily withstood.

Each standard length of chain ( 27.5 m or part thereof ) is connected to the adjoining length by a Dee type joining shackle or lugless joining shackle ( Kenter type ). When Dee type joining shackle is used, each length shall include one enlarged link and one end link at each end. Each length of chain shall be provided with one Dee type joining shackle and shall comprise of an odd number of links exclusive of the joining shackle.

When lugless ( Kenter type ) joining shackle is used, enlarged and end links of increased dimensions are obviated. A common link acts as the end link in any one length of chain. Each length of chain shall be provided with one lugless shackle.

In formulating this standard assistance has been derived from IS0 1704 : 1991 ‘Shipbuilding - Stud-link anchor chains’.

The committee responsible for the preparation 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 same as that of the specified value in this standard.

3 TERMINOLOGY

For the purpose of this standard, the following defini- tions shall apply.

3.1 Stud Link

The link of an anchor chain with a stud across its minor axis.

3.2 Common Link

The stud linkwith which a chain is normally constituted (see Fig. 1).

3.3 Enlarged Link

The stud link of increased dimensions to connect the end link with a common link (see Fig. 1).

3.4 End Link

The studless link of enlarged dimensions to enable the

use of Dee type shackle (see Fig. 1).

3.5 Dee ‘Qpe Joining Shackle

Dee type shackle is used for joining two consecutive lengths ofanchorchains (seeFig. 1). This is also known as bolt type shackle.

3.6 End Shackle

End shackle is similar to Dee type shackle but of different dimensions and used to connect the anchor shackle with the anchor chain (see Fig.1).

3.7 Kenter ‘Ijpe Joining Shackle

This type of shackle, when assembled, resembles the stud link and used for joining two consecutive lengths of anchor chains (see Fig.1).

NOTE -Material specification for the retaining pin to be stainless steel or equivalent. The vacant space at the larger end of the pin be filled with lead or any other equivalent compound and to be made flush with the contour of the shackles.

3.8 Swivel Piece

The swivel consists of a swivel with up to 3 studded links at one or both ends. This is incorporated in the chain cable to prevent twisting (see Fig. 1).

3.9 Nominal Diameter

Nominal diameter is the designated diameter of the common link in millimetres and is indicated by d.

4 MATERIAL

4.1 Steel used for the manufacture of chains shall have the following mechanical properties as per table given below:
