It is the UK implementation of, and is identical to, ISO 8484:1987 “Magnetic stripes on savingsbooks”, published by the International Organization for Standardization (ISO), except that the title of the British Standard differs in order to more accurately reflect the actual contents of the text, taking into account also the features identified in the paragraphs below (headed “Special attention”). This standard implements the international text without change for the reasons given below (see “Reasons for implementation”), even though particular attention is drawn. (see “Special attention”) to some features that may need special consideration when this standard is being used. (UK participation in future development, revision or amendment of the International Standard will include requests for attention to these points.) The UK actively participated in the development of the International Standard through BSI Technical Committee IST/17 and fully approved publication of the International Standard. The information provided is considered sufficient to act in the UK as a basis for the design and use of savings books of the types covered by the International Standard. There are no plans at present to supplement this British Standard with any additional guidance, and any comments or enquiries on the International Standard or its application should be addressed to the Secretary to IST/17 at the BSI headquarters. Reasons for implementation a) Because information technology equipment, services and systems tend to be, and generally need to be, designed, purchased and used in a world-wide context IST/- policy is to agree, wherever possible, standards at international level and not to prepare unique national standards. At the time of its approval, the text of the International Standard was considered to be the best that could be achieved, taking into account both the needs of the “market place” and the “state of the art” in this subject area, and the International Standardization process. b) Further development of the international text at international level has been accorded relatively low priority in relation to other projects in the same international committee. c) Publication of British Standards corresponding to the International Standards in which IST/- resources were invested will ensure that the BSI Catalogue becomes, and then remains, a comprehensive first source of information for UK users of information technology equipment and services about the availability of International Standards on information technology subjects. In turn, this will facilitate UK use of, and access to, those standards. Special attention Special attention is drawn to the following features of the International Standard that, ideally, require further consideration at international level, but it is emphasized that these features do no prevent use of this standard as a set of basic guidelines and, with appropriate care, products can be effectively standardized. Users of this British Standard, however, might need supplementary information on these features from the BSI Technical Committee or from experts in the field. (Note that, whilst agreements between individual trading or communicating partners can be made, and might suffice, additional care might be needed to avoid creating agreements that differ only slightly between different parties.) a) Clause 2 includes ISO 7811-5, but there is no direct reference in the international text to that standard, only an indirect reference in the note to clause 5.

If testing is carried out by different agencies care might be needed, to identify the degree of comparability of tests and results. (An ISO text “I.D. cards Test methods” is in preparation and may lead to additions appropriate to this standard.) d) Care might be needed in using test results achieved after conditioning in conformity with clause 6 to project or make any claim about performance over the wider environment described in clause 7. (It might be necessary or advisable to carry out additional tests under the more extreme conditions.) The BSI Technical Committee has reviewed the provisions of TAPPI T489 os-76, to which reference is made in the text, and has decided that it is acceptable for use in conjunction with this British Standard but see item b) of “Special attention”. Information on the availability of interim ISO documents, as well as up-to-date information on existing and projected British Standards publications in the general area of Information Technology, is included in the “BASIC LIST” and regular Newsletter published as part of the BSI Information Technology Services (BITS) initiative.

Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

Compatibility with international interchange systems is provided through the requirements of this International Standard, enabling a magnetic striped savingsbook to be read and possibly encoded in a device that is compatible with reading identification cards used in international interchange. National systems may use different specifications. 1 Scope and field of application This International Standard specifies the location, dimensions, electromagnetic properties, recording characteristics, character coding and character set of magnetic stripes on savingsbooks used in interchange. This International Standard describes features of the savingsbook cover i.e. stiffness, minimum dimensions, surface irregularities, roughness as well as the interaction between cover material and magnetic stripe. This International Standard does not include requirements for the contents of recording or use of certain control characters. 2 References ISO 7811, Identification cards Recording technique Part 2: Magnetic stripe Part 5: Location of read-write magnetic track Track 3.

Two positions are defined relative to one corner and the adjacent edges (see Figure 1). 4.1 Parallel to printline If the reader-encoder is integrated into a savingsbook printer, the magnetic stripe shall be parallel to the printline (see Figure 1). 4.2 Parallel to fold In applications where a separate reader-encoder is used, it is generally preferable to have the stripe parallel to the fold, irrespective of the type of savingsbook used. 5 Area of magnetic material The minimum area to be covered by magnetic material shall be as shown in Figure 2. NOTEThis area is based on the use of a read-write track equivalent to track 3 on an identification card. 6 Requirements and testing Before testing is carried out, the savingsbook shall be stored for a minimum of 24 h in an environment with a temperature of 23 ± 2 °C and relative humidity of 50 ± 10 %. Testing shall be carried out in the same environment. All signal amplitude measurements shall be performed in such a way that the values measured are proportional to the voltage induced in the read head. Prior to issue all savingsbooks shall satisfy the following requirements: 6.1 Properties of the savingsbook cover with magnetic stripe 6.1.1 Stiffness For the determination of stiffness the bending moment is used. In the direction of the magnetic stripe the bending moment shall be not less than 16 × 104N·m when tested in accordance with TAPPI T489 os-76.

Measurements shall be made with a cut-off wavelength of 0,8 mm (0.030 in) using a probe with a nominal radius of 2,5 4m (100 4in). The average roughness shall not be more than 1,4 4m (55,1 4in). 6.1.4 Cover material After the magnetic stripe has been placed on the savingsbook cover, there shall be no reaction between the cover and the magnetic stripe which would cause any malfunction of the magnetic stripe in normal use. The magnetic stripe sh
