Overview
SIST EN ISO 3819:2016 is an international standard specifying requirements for laboratory glassware, specifically beakers. Developed by the International Organization for Standardization (ISO) and adopted by the European Committee for Standardization (CEN), this standard ensures that glass beakers used worldwide meet consistent quality, dimensional, and performance criteria for laboratory applications. It applies to an internationally acceptable series of borosilicate glass beakers designed for reliable use in laboratory settings.
Key Topics
-
Types of Beakers
The standard defines three types of glass beakers:
- Low-form beakers with spout
- Low-form thick-walled beakers with spout
- Tall-form beakers with spout
-
Capacity and Size Series
Beakers range in nominal capacities from 5 ml to 10,000 ml, with specific series defined for each type and wall thickness. The capacity design accounts for overflow volume and volume gradation for accurate laboratory measurements.
-
Material Requirements
Beakers must be made of borosilicate glass 3.3, compliant with ISO 3585. The glass is required to be free from residual strain and visible defects that could affect safety and performance.
-
Dimensional Tolerances and Construction
The standard specifies detailed dimensions including external diameter, height, wall thickness, and base radius. Wall thickness varies by beaker size and type, ensuring durability and thermal resistance. The beaker construction includes design criteria for a stable base, flared upper edge, and effective spout to facilitate smooth pouring without spillage.
-
Thermal Shock Resistance
Beakers must withstand thermal shocks of up to 160 °C per the ISO 718 test methods, ensuring they remain safe and intact under rapid temperature changes often encountered in laboratory procedures.
-
Marking and Identification
Each beaker must have permanent, legible markings indicating nominal capacity, manufacturer’s identification, and glass type. Additionally, a writable area for pencil marking supports laboratory record-keeping.
Applications
SIST EN ISO 3819:2016 compliant beakers are essential tools in various laboratory environments including:
- Chemical laboratories – For precise volume measurement, mixing, and heating of chemical substances.
- Biological research labs – Used for sample preparation and reagent mixing under strict safety and quality standards.
- Pharmaceutical development – Critical for formulation testing and quality control to ensure reproducibility and safety.
- Educational institutions – Providing standardised glassware for instruction and accurate experimental work.
- Industrial laboratories – Supporting material testing, quality assurance, and research initiatives with reliable glassware.
By adhering to this standard, laboratories can ensure the safety, accuracy, and compatibility of glass beakers used in scientific and industrial processes.
