Thi
6、s 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 stage of manufacture o
7、r use. In particular, attention is drawn to the lightfastness test inAnnex 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 does not of itself con

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in
9、 the amendment table on the inside front cover.BS3484-2:1994 BSI 06-1999 1 1 Scope This Part of BS3484 specifies performance and marking for inks which are applied by nib-type pens or another application medium, e.g.roller ball pens, and which are intended for documents which may have a very long wo
10、rking 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 document also depends on the composition of the paper on which it is written, storage conditions, etc. NOTE 2Although security features can b
11、e 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 specially formulated background printing inks. These, used singly or in combination, will make alteration more difficult. 2 Normative references
12、This Part of BS3484 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on the inside back cover. Subsequent amendments to, or revisions of, any of these public
13、ations apply to this Part of BS3484 only when incorporated in it by updating or revision. 3 Definition For the purposes of this Part of BS3484, the following definition applies. permanent record inks inks suitable for creating records which are required to be preserved for long periods of time and w
14、hich possess a high degree of resistance to eradication 4 Performance When tested in accordance with the methods described inAnnex A the ink shall: a) show no strike through; b) be visually recognizable as being of its original colour when tested in accordance with A.4.2; c) show resistance to fadin
15、g not less than equivalent to that of blue wool number5, grey scale number4, when tested in accordance withA.4.3; d) show sufficient resistance to physical erasure such that, when tested in accordance with A.4.4, a definite line still exists; e) show sufficient resistance to chemical eradication suc
16、h 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 instruments containing permanent record ink shall be legibly marked with the following information: a) the name, trade mark or other means of i
17、dentifying the manufacturer; b) the date or date code of manufacture; c) the number and date of this British Standard, i.e.BS3484-2:1994 1) . 1) Marking BS3484-2:1994 on or in relation to a product represents a manufacturers declaration of conformity, i.e.a claim by or on behalf of the manufacturer
18、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 confused with third party certification of conformity, which may also be desirable.BS3484-2:1994 2 BSI 06-1999 Annex A (normative) Determination

20、racteristics as given inTable A.1. A.2 Procedure A.2.1 General Carry out the test piece preparation in the standard atmosphere specified in BS EN20187:1993 and then follow the procedure of eitherA.2.2 orA.2.3. A.2.2 Write test machine Load the write test machine(A.1.1) with the appropriate paper(A.1
21、2) for the ink to be tested and adjust the machine to give a writing pattern of a continuous spiral line10cm in circumference. Set the machine in motion and produce the continuous test pattern for a length of105m. Condition the test length in the standard atmospheric conditions for24h. A.2.3 Manual
22、 method Using the ink in a writing instrument recommended by the ink manufacturer, draw lines of a total length of at least30m on the paper specified for liquid ink pens inA.1.2. Condition the test length in the standard atmospheric conditions for24h. A.3 Visual examination A.3.1 General The first5m
23、 of writing shall be discarded and the examinations as given inA.3.2 andA.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
24、 examined.

Carry out the following tests. A.4.2 Fastness to water Immerse a test
27、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 for24h. At the end of this period examine the water and the test piece for signs of ink migration. Dry the test piec
28、e and compare its colour with the original in light conditions conforming to BS950-1:1967. A.4.3 Lightfastness Take one test piece and expose to light for48h in accordance with BS EN20105-B02:1993. At the end of this period the resistance to fading shall be at least equivalent to blue wool number5,
29、grey scale number4, when examined in light conditions conforming to BS950-1:1967. 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 paper is just visibly damaged. Examine the ink trace. A.4.5 Resistance to chemical
30、eradication To one test piece apply drops of the solutions listed below. After10min blot off with lint-free absorbent paper or cotton wool and allow to dry. Visual examination with the unaided eye shall not show any loss of ink integrity. a) 50% v/v aqueous solution of ethanol (C 2 H 5 0H). b) 10% v
31、/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 of6% hydrogen peroxide(20volume H 2 O 2 ) achieved by adding a few drops of0,880 ammonia solution,
32、 until the first appearance of bubbles. NOTEThis is equivalent to approximately0.25ml of ammonia solution per10ml of hydrogen peroxide solution.4 blankBS 3484-2:1994 BSI 06-1999 List of references (see clause2) Normative references BSI publications BRITISH STANDARDS INSTITUTION, London BS950, Specif
