Full title and description

ISO 1773:1976 — Laboratory glassware — Boiling flasks (narrow-necked). This International Standard defines the designation, main dimensions and general requirements for narrow‑necked boiling flasks used in laboratory heating and boiling operations (title translated into Russian: "Лабораторная стеклянная посуда — Колбы для кипячения (узкогорлые)").

Abstract

ISO 1773:1976 specifies the principal dimensions, nominal capacities, marking and basic requirements for narrow‑necked boiling flasks intended for laboratory use. The edition from 1976 was short (3 pages) and provided dimensional and identification conventions for manufacturers, purchasers and laboratories; it was later revised by a new edition.

General information

• Status: Withdrawn (superseded by a later edition).
• Publication date: August 1976 (Edition 1, 1976-08).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.040.20 — Laboratory glassware.
• Edition / version: Edition 1 (1976).
• Number of pages: 3 pages.

Scope

This standard covers narrow‑necked boiling flasks (commonly used in heating and boiling operations in chemical and clinical laboratories), specifying nominal volumes and principal dimensions, identification/marking and general requirements relevant to manufacturing and procurement. The 1976 edition has since been withdrawn and the subject matter updated in the 1997 revision.

Key topics and requirements

• Designation and identification of narrow‑necked boiling flasks (nomenclature and marking requirements).
• Principal dimensions and nominal capacities for standard sizes (nominal volume ranges and corresponding geometry).
• Material and construction expectations for laboratory glassware suitable for heating (typical: borosilicate-type laboratory glass).
• Tolerances and permissible deviations for volume and dimensions (to ensure interchangeability and reliable use in laboratory procedures).
• Reference to the later revision (ISO 1773:1997) for the up‑to‑date requirements and any expanded dimensional series.

Typical use and users

Manufacturers of laboratory glassware, procurement specialists for laboratories, quality and compliance personnel, laboratory managers and standards librarians use this standard to specify and verify narrow‑necked boiling flasks for educational, research and industrial laboratories. Laboratories rely on the dimensional and marking conventions for equipment ordering and cross‑supplier compatibility.

Related standards

ISO 1773:1997 (the later edition that revised and replaced the 1976 version) is the primary related document. More general and national standards on laboratory glassware (for example national GOST standards covering laboratory measuring and boiling vessels) are also relevant for regional conformity and practice.
