SPECIFICATION FOR STOCK ANCHORS

( First Revision )

0. FOREWORD

0.1 This Indian Standard was adopted by the Indian Standards Jnstitu- tion on 30 January 1981, after the draft finalized by the Shipbuilding Sectional Committee had been approved by the Marine, Cargo Movement and Packaging Division Council.

0.2 An anchor is designated by its nominal mass. The dimensions of the anchor and its component parts depend upon the nominal mass and the design features of the anchor.

0.3 This standard was first published in 1966. The need for the revision of this standard was felt regarding the range of nominal mass.

0.4 In the formulation of this standard due weightage has been given to international coordination among the standards and practices prevailing in different countries in addition to relating it to the practices in the field in this country. This has been met by basing the following publications:

JIS F 3301 : 1975 Anchors, Japanese Industrial mittee

PN W 83051 : 1961 Admiralty anchor. Polish mittee

0.5 This standard is one of a series of Indian Standards on anchors. Other standards in the series are:

IS : 3267-1981 General requirements for anchors (first revision )

IS : 3268-1981 Specification for stockless anchors ( for ships’ use ) (first revision )

IS : 3270-1966 Specification for stock and single fluke stock anchors ( for harbour use )

0.6 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 accordance with

3

IS t 3269 = 1981

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

1.1 This standard specifies the nominal mass (ranging from 25 to 2 160 kg ), dimensions and materials for the various components of stock anchors.

2. TERMINOLOGY

2.1 For the purpose of this standard the definitions given in IS : 3267- 1981? shall apply.

3. DIMENSIONS AND MASS

3.1 Mass and dimensions for stock anchor and its components shall be as given in Tables 1 and 2. All the dimensions are based on the basic dimension A = S = 24.45 3vg, where G is the nominal mass of stock anchor in kilograms.

3.1.1 The mass and dimensions for stock anchors and anchor shackles shall be as given in Table 1 read with Fig. 1.

3.1.2 The mass and dimensions for stock together with its locking arrangement shall be as given in Table 2 read with Fig. 2.

3.2 The dimensions of various parts of stock anchor shall not vary by more than 4, percent from the specified values. The variation of any dimension from the specified value shall not exceed 20 mm.

3.3 Machining tolerances shall conform to coarse series of IS : 2102-1969$.

3.4 The mass of different components shall not vary by more than 5 per- cent from the specified value of the mass of these components, provided the total mass of anchor is not less than the nominal mass given in Tables 1 and 2.

4. MATERIAL FOR CONSTRUCTION

4.1 The material for the construction of stock anchor and its various components shall be as specified in IS : 3267-1981t.

*Rules for rounding off numerical values ( revised ). TGeneral requirements for anchors (Jirst revision ). SAllowable deviation for dimensions without specified tolerances (jrst revision).

4.3 The chain and split pin shall be of mild steel and of suitable size in proportion to that of washer and cotter.

5.. TESTS

5.1 Stock anchors shall be tested according to the tests prescribed in IS : 3267-1981:.

6. DESIGNATION

NOTE - The use of the IS1 Certification Mark is governed by the provisions of the Indian Standards Institution ( Certification Marks) Act and the Rules and Regulations made thereunder. The IS1 Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-defined system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continuously checked by IS1 for conformity to that standard as a further safeguard. Details of conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may be obtained from the Indian Standards Institution.
