7、Policy Committee. This specification calls for the use of a test procedure that may be injurious to health if adequate precautions are not taken. It refers only to technical suitability and in no way absolves the user of this standard from statutory obligations relating to health and safety at any s
8、tage of manufacture or use. In particular, attention is drawn to the lightfastness test in Annex A. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard
9、does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated.
10、 This will be indicated in the amendment table on the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 29 08:47:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 3484-2:1994 BSI 06-19991 1 Scope This Part of BS 3484 specifies performance and marking for inks which are applied b
11、y nib-type pens or another application medium, e.g. roller ball pens, and which are intended for documents which may have a very long working and storage life. Annex A gives details of tests for compliance of the ink with this Part of this British Standard. NOTE 1The long-term durability of any docu
12、ment also depends on the composition of the paper on which it is written, storage conditions, etc. NOTE 2Although security features can be introduced into writing inks, making the resulting script more difficult to alter, the producer of the original document may wish to consider the use of speciall
13、y formulated background printing inks. These, used singly or in combination, will make alteration more difficult. 2 Normative references This Part of BS 3484 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate p
14、oints in the text and the publications are listed on the inside back cover. Subsequent amendments to, or revisions of, any of these publications apply to this Part of BS 3484 only when incorporated in it by updating or revision. 3 Definition For the purposes of this Part of BS 3484, the following de
15、finition applies. permanent record inks inks suitable for creating records which are required to be preserved for long periods of time and which possess a high degree of resistance to eradication 4 Performance When tested in accordance with the methods described in Annex A the ink shall: a) show no
16、strike through; b) be visually recognizable as being of its original colour when tested in accordance with A.4.2; c) show resistance to fading not less than equivalent to that of blue wool number 5, grey scale number 4, when tested in accordance with A.4.3; d) show sufficient resistance to physical
17、erasure such that, when tested in accordance with A.4.4, a definite line still exists; e) show sufficient resistance to chemical eradication such that, when tested in accordance with A.4.5, a definite line still exists. 5 Marking Each bottle or container of permanent record ink or package of writing
18、 instruments containing permanent record ink shall be legibly marked with the following information: a) the name, trade mark or other means of identifying the manufacturer; b) the date or date code of manufacture; c) the number and date of this British Standard, i.e. BS 3484-2:19941). 1) Marking BS
19、3484-2:1994 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be
20、 confused with third party certification of conformity, which may also be desirable.

22、ure A.2.1 General Carry out the test piece preparation in the standard atmosphere specified in BS EN 20187:1993 and then follow the procedure of either A.2.2 or A.2.3. A.2.2 Write test machine Load the write test machine (A.1.1) with the appropriate paper (A.1.2) for the ink to be tested and adjust
23、the machine to give a writing pattern of a continuous spiral line 10 cm in circumference. Set the machine in motion and produce the continuous test pattern for a length of 105 m. Condition the test length in the standard atmospheric conditions for 24 h. A.2.3 Manual method Using the ink in a writing
24、 instrument recommended by the ink manufacturer, draw lines of a total length of at least 30 m on the paper specified for liquid ink pens in A.1.2. Condition the test length in the standard atmospheric conditions for 24 h. A.3 Visual examination A.3.1 General The first 5 m of writing shall be discar
25、ded and the examinations as given in A.3.2 and A.3.3 shall be carried out on the remainder. A.3.2 Ink deposition When examined the test length shall show a consistent quality of line. A.3.3 Strike through There shall be no ink visible on the underside of the test length when examined. Table A.1 Char

29、th. Carry out the following tests. A.4.2 Fastness to water Immerse a test piece in a shallow dish of appropriate size, for example a petri dish, and add the minimum quantity of water to just cover the test piece. Cover the dish and leave at room temperature for 24 h. At the end of this period examin
30、e the water and the test piece for signs of ink migration. Dry the test piece and compare its colour with the original in light conditions conforming to BS 950-1:1967. A.4.3 Lightfastness Take one test piece and expose to light for 48 h in accordance with BS EN 20105-B02:1993. At the end of this per
31、iod the resistance to fading shall be at least equivalent to blue wool number 5, grey scale number 4, when examined in light conditions conforming to BS 950-1:1967. A.4.4 Resistance to physical erasure Take two test pieces and abrade each manually with a glass filled eraser until the surface of the
32、paper is just visibly damaged. Examine the ink trace. A.4.5 Resistance to chemical eradication To one test piece apply drops of the solutions listed below. After 10 min blot off with lint-free absorbent paper or cotton wool and allow to dry. Visual examination with the unaided eye shall not show any
33、 loss of ink integrity. a) 50 % v/v aqueous solution of ethanol (C2H50H). b) 10 % v/v aqueous solution of hydrochloric acid (HCl). c) 10 % m/m aqueous solution of sodium hydroxide (NaOH). d) 2 % m/m aqueous solution of chloramine T. e) Bleaching solution. A slightly ammoniacal solution of 6 % hydrog
34、en peroxide (20 volume H2O2) achieved by adding a few drops of 0,880 ammonia solution, until the first appearance of bubbles. NOTEThis is equivalent to approximately 0.25 ml of ammonia solution per 10 ml of hydrogen peroxide solution. Licensed Copy: sheffieldun sheffieldun, na, Wed Nov 29 08:47:59 G
