Understanding BIS Certificate for Graduated Measuring Cylinders - IS 878:2008
Graduated measuring cylinders are designed to measure liquid volumes with a certain degree of precision. Unlike decorative glassware, these instruments are used in scientific and industrial processes where measurement accuracy directly affects outcomes. Therefore, the evaluation of such products goes far beyond visual inspection.
BIS Certification for Laboratory glassware – Graduated measuring cylinders focuses on several critical aspects:
- Measurement accuracy: The graduation markings must reflect true volume levels without significant deviation.
- Glass composition: The material should resist chemical reactions, thermal stress, and mechanical impact.
- Graduation clarity: Markings must remain legible even after repeated use and cleaning.
- Structural stability: Cylinders must stand upright without tipping, especially when filled with liquid.
For example, in a pharmaceutical lab, an incorrectly calibrated measuring cylinder can lead to incorrect dosage formulation, which may compromise product safety. Similarly, in educational settings, inaccurate cylinders can lead to incorrect learning outcomes.
The purpose of BIS Certification for Laboratory glassware – Graduated measuring cylinders is to ensure that each unit produced adheres to consistent standards, regardless of the manufacturer or batch. It also ensures that the product behaves predictably under various laboratory conditions.

1. Accuracy Testing
This test verifies whether the cylinder measures liquid volumes correctly.
- Water is filled up to specific graduation marks
- The actual volume is compared with the indicated value
- Permissible tolerance limits are defined in the standard
Example: A 100 ml cylinder should not deviate beyond the specified tolerance when filled to the 100 ml mark.
2. Thermal Resistance Test
Measuring cylinders are often exposed to temperature variations.
- The glass is subjected to sudden temperature changes
- The cylinder is observed for cracks or deformation
This ensures the cylinder can handle hot or cold liquids without failure.
3. Chemical Resistance Test
Since cylinders come in contact with chemicals:
- The glass is exposed to acidic and alkaline solutions
- Any reaction, discoloration, or degradation is evaluated
This prevents contamination of samples during experiments.
4. Graduation Durability Test
Graduation markings must remain visible over time.
- The markings are subjected to washing, abrasion, and chemical exposure
- The clarity and permanence are checked
5. Stability Test
The cylinder must remain upright when placed on a flat surface.
- The base design is tested for balance
- Stability is checked under filled and empty conditions
6. Dimensional Verification
- Height, diameter, and wall thickness are measured
- Ensures uniformity across batches
