FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Paper and Its Products (Excluding Packaging Materials) Sectional Committee had been approved by the Chemical Division Council.
Toilet paper is extensively used for domestic as well as industrial and medical purposes. The quality toilet paper depends on a variety of characteristics such as bursting and tensile strength, water absorption, etc. Some of the desirable characteristics of toilet paper such as softness, non-disintegration in use, and ready dissolution after use, are qualitative in nature and cannot be specified in detail at the present time.
A scheme for labelling environment friendly products known as ECO Mark has been introduced at the instance of the Ministry Environment and Forest (MEF), Government of India. The ECO Mark scheme would be administered by the Bureau of Indian Standards (BIS) under the Bureau of Indian Standard Act, 1986 as per the Resolutions No. 71 dated 21 February 1991 and No. 425 dated 28 October 1992 published in the Gazette of the Government of India. For a product to be eligible for marking with ECO logo, it shall also carry the ISI Mark of BIS besides meeting additional environment friendly requirements. For this purpose, the Standard Mark of BIS would be a single mark being a combination of the ISI Mark and the ECO logo. Requirements to be satisfied for a product to qualify for the BIS Standard Mark for ECO friendliness have been incorporated in this standard based on the Gazette Notification No. 455 dated 13 November 1992 for paper as environment friendly products published in the Gazette of India. These requirements will be optional, manufacturing units will be free to opt for the ISI Mark alone also.
The composition of the Committee responsible for formulation 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 the same as that of the specified value in this standard.

DETERMINATION OF ABSORPTION TIME
B-1 APPARATUS AND MATERIALS
B-1.1 Volume measuring device, syringe, capable of measuring 0.01 ml volume.
B-1.2 Specimen support, a piece of metal or other non-absorbent material about 100 × 100 mm, with a central hole of approximately 40 mm diameter.
B-1.3 Light source, to reflect light from the surface of unabsorbed water on the specimen, situated far enough away so that its heat will not influence the absorption time.
NOTE - A 1.5-V flashlight bulb, shaded from the eyes, placed about 200 mm above and to the rear of the support and operated by a 'D' cell battery or a bell transformer, makes a very good light source for this purpose.
B-1.4 Timer, stopwatch or electric timer readable to 0.2 s or better.
B-1.5 Distilled water.
B-2 SAMPLING AND TEST SPECIMENS
B-2.1 Obtain a representative sample of the paper. From each sample cut 10 specimens, each approximately 100 × 100 mm.
B-3 PROCEDURE
B-3.1 Condition and test the specimens in the conditioning and testing atmosphere temperature 27 ± 1°C and relative humidity 65 ± 2 percent for at least one hour prior to testing.

Amend No. 1 to IS 14661 : 1999
B-3.2 Place a test specimen on the horizontal support which has a clear space of at least 10 mm beneath it. Do not stretch or in any way distort the test specimen, as this may change the results from the test. Fill the syringe with distilled water at 27 ± 1°C.
B-3.2.1 Hold the tip vertical of syringe, express a volume 0.01 ml, and apply the volume directly to the specimen.
B-3.3 Start the timer as soon as the water contacts the specimen and measure the time for the water to be completely absorbed to the nearest 0.2 s or better, as indicated visually by the disappearance specular reflection of light (or the moment of disappearance of the glossy or shiny area from the wet spot).
B-3.4 Conduct the test where neither heat from the light nor a strong current of air might influence the result.
B-3.5 Repeat the procedure on the other nine test specimens.
B-4 REPORT
B-4.1 Report the volume used, and the average absorption time in seconds, to the nearest second if over 10 s, or to the nearest 0.2 s if less than 10 s.
