IS 1448 : Part 25 : Sec 2 : 2025/ISO 3105 : 1994 Petroleum and its Products - Methods of Test - Part 25 Glass Capillary Kinematic Viscometers - Section 2 Specifications and Operating Instructions
NATIONAL FOREWORD
This Indian Standard (Part 25/Sec 2) which is identical to ISO 3105 : 1994 'Glass capillary kinematic viscometers specifications and operating instructions' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Methods of Sampling and Test for Petroleum and Related Products of Natural or Synthetic Origin (excluding bitumen) Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.
The standard IS 1448 (Part 25) was first published in 1976 by adapting joint publication ASTM D 445-72 and IP 71-75. The Committee decided to harmonize the standard with international standard. As the scope of IS 1448 (Part 25) was covered under two different ISO standards that is ISO 3104 and ISO 3105, it was decided to bifurcate IS 1448 (Part 25) into two sections corresponding to each of the ISO standard. Accordingly, two separate standards have been published, Section 1 covering methods of test and Section 2 covering the specification and operating instructions for glass capillary viscometers.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
