Описание (английский):

ISO 648:2008 specifies metrological and constructional requirements for volumetric pipettes with one mark (total delivery) and for volumetric pipettes with two marks, both of which are adequate for general laboratory purposes. The details specified are in conformity with the principles of design and construction of volumetric glassware given in ISO 384.

Overview

SIST EN ISO 648:2008 - Laboratory Glassware: Single-Volume Pipettes establishes the international requirements for the design, construction, and performance of single-volume (volumetric) pipettes made from glass. These precision instruments are critical for measuring and delivering accurate volumes of liquid in laboratory settings. The standard specifies both pipettes with one mark (total delivery) and pipettes with two marks, suitable for general laboratory applications. Complying with SIST EN ISO 648:2008 ensures consistent accuracy, reliability, and safety across laboratories worldwide.

Key Topics

Scope and Definitions

Applies to glass volumetric pipettes with either one mark (for total delivery) or two marks.
Defines key concepts such as delivery volume, delivery time, and waiting time.

Accuracy Classes

Class A and AS: Higher precision, suitable for tasks requiring stricter measurement accuracy.
Class B: Lower grade, offering more flexibility for general use.

Design and Construction

Specifies requirements for materials with adequate chemical and thermal resistance.
Outlines construction parameters including shape (straight tube or bulb pattern), overall and component dimensions, and smoothness of the delivery jet.
Details on marking, graduation lines, and legibility to promote consistent and user-friendly usage.

Performance Requirements

Sets maximum permissible errors for various nominal volumes.
Stipulates delivery times and waiting times (for Class AS pipettes).
Aligns all aspects with ISO 384 principles for volumetric glassware.

Marking and Identification

Pipettes must be permanently marked with nominal volume, unit, reference temperature, accuracy class, and manufacturer information.
Recommendations for color coding and standardized inscriptions for clarity and traceability.

Applications

SIST EN ISO 648:2008 is essential for any setting where precise measurement and transfer of liquid volumes are critical. Applications include:

Analytical and Clinical Laboratories Ensures that chemical and biological analyses use accurate liquid handling, leading to reliable results and reproducible processes.

Pharmaceutical Testing Used in preparation and dilution of reagents, ensuring dosage and formulation consistency.

Environmental Monitoring Facilitates accurate water sampling and chemical analyses as required for compliance and research activities.

Food and Beverage Testing Important for quantitative analyses of ingredients and contaminants.

Educational and Research Labs Provides a foundational standard for training students and conducting controlled scientific experiments.

Standardized pipettes minimize variability, reduce measurement uncertainties, and help maintain compliance with national and international regulations, supporting laboratory accreditation and quality management initiatives.
