IS 1117:2018 addresses Laboratory glassware - Single Volume pipettes. This Indian Standard was adopted by the Bureau of Indian Standards following a recommendation from the Glass, Glassware, and Laboratory Ware Sectional Committee and approval from the Chemical Division Council.

This standard outlines the sampling and testing criteria, as well as methods, for one-mark pipettes designed for general laboratory applications. Single-volume pipettes should be constructed from glass with chemical resistance and thermal properties meeting or exceeding HGB3 standards outlined in ISO 719. They should exhibit minimal visible defects and be reasonably free from internal stress. A BIS license for Laboratory glassware Single Volume pipettes authorizes the use of the Standard Mark in compliance with IS 1117:2018/ISO 648:2008.

One-mark pipettes are categorized into two accuracy classes, A and B, based on nominal capacities and precision standards. These pipettes should be manufactured from colorless glass without any noticeable tint, and they should exhibit minimal visible defects and reasonable freedom from internal strain. The pipettes must adhere to the standard's dimensional specifications as well as requirements for workmanship and finish. Maintaining a well-equipped laboratory with sufficient staff is necessary to conduct the various tests detailed in the standard.

TESTS

The following tests are necessary for Single Volume Pipettes.

• Maximum permissible errors

• Material

• Dimensions

• Delivery time

• Graduation line

PACKING AND MARKING

Each one-mark pipette should be appropriately labeled according to IS 1117:2018 standards, with the option to apply a Standard Mark to each pipette. Packaging should be determined through mutual agreement between the buyer and supplier. All production meeting the Indian Standard and holding a license must display the standard ISI Mark. Manufacturers seeking to use the standard mark must obtain a BIS license for one-mark pipettes from the Bureau of Indian Standards. This license is granted following a thorough assessment of manufacturing infrastructure, quality control measures, testing capabilities, and production processes. BIS certification for one-mark pipettes is essential to ensure compliance with applicable Indian standards.
