Full title and description

ISO 385-2:1984 — Laboratory glassware — Burettes — Part 2: Burettes for which no waiting time is specified. Specifies requirements for certain type I burettes including capacity, test method, delivery time and method of use; these burettes shall conform to the general requirements given in ISO 385‑1.

Abstract

This short standard (2 pages) defines metrological and construction-related requirements and test procedures for burettes where no waiting time is specified (type I). It sets capacity tolerances, the method of delivery and the recommended test procedure; it refers to the general principles for volumetric glassware in ISO 384 and to the companion part ISO 385‑1 for general requirements.

Scope

Defines requirements and tests for type I burettes for which no waiting time is specified, covering capacity classes, delivery time and prescribed methods of use and testing. It is intended to harmonize dimensional and metrological characteristics of such burettes for general laboratory use and to be used together with ISO 385‑1 (general requirements) and ISO 384 (principles for volumetric glassware).

Key topics and requirements

• Definition of type I burettes for which no waiting time is specified.
• Capacity classes and permissible tolerances for declared volumes.
• Specified test method(s) for verifying delivered volume and delivery time.
• Instructions on method of use and handling to achieve stated accuracy.
• Requirement to conform with general requirements in ISO 385‑1 and design principles in ISO 384.

Typical use and users

Used by chemical and clinical laboratories, manufacturers of volumetric glassware, quality and calibration laboratories, standards bodies and procurement/specification teams that require harmonized acceptance criteria for burettes used in titration and volumetric analysis. Also referenced by test laboratories when validating volumetric transfer accuracy.

FAQ

Q: What is this standard?

A: ISO 385‑2:1984 is a part of the ISO series on laboratory burettes that specifically addressed burettes for which no waiting time is specified (type I). It provided definitions, capacity classes, test methods and instructions for use.

Q: What does it cover?

A: It covers metrological and construction-related requirements for specified burettes: declared volumes and tolerances, delivery characteristics and the procedures for testing and use to ensure accurate volumetric delivery. It is short (2 pages) and intended to be used alongside ISO 385‑1 and ISO 384.

Q: Who typically uses it?

A: Laboratory personnel performing titrations and volumetric work, manufacturers of burettes and volumetric glassware, quality assurance and calibration laboratories, and standards/technical committees creating procurement or compliance specifications.

Q: Is it current or superseded?

A: ISO 385‑2:1984 has been withdrawn and superseded by the consolidated ISO 385:2005. The 1984 parts (including 385‑2) were withdrawn in the revision process; users should refer to ISO 385:2005 for the current consolidated requirements.

Q: Is it part of a series?

A: Yes — it formed part of the ISO 385 series (parts 1–3 as published in 1984) which in turn replaced ISO/R 385 (1964); the series was later consolidated into ISO 385:2005.

Q: What are the key keywords?

A: Burette, laboratory glassware, volumetric, capacity tolerance, test method, delivery time, ISO 385, ISO 384.
