ASTM E1405-98(2022)

Overview

ASTM E1405-98(2022): Standard Specification for Laboratory Glass Distillation Flasks is an internationally recognized standard provided by ASTM International. This specification outlines the standard dimensional requirements and manufacturing characteristics for glass distillation flasks used in laboratories. These flasks are essential tools for performing various distillation processes, particularly in petroleum testing and general chemical analysis. The standard covers both general-purpose flasks and those designed for specific testing applications, ensuring reliability and consistency in laboratory environments.

Key Topics

• Flask Types and Classes

  • Type I: General purpose distillation flasks available in a range of nominal capacities including 10, 25, 50, 125, 200, 250, 500, 1000, and 2000 mL.
  • Type II: Flask designed for special tests, subdivided into Classes 1 to 5, each associated with specific nominal capacities and test methods (e.g., Barrett, Church, Engler, Hempel, Saybolt).

• Materials and Manufacturing

  • Flasks are constructed from high-quality borosilicate glass, conforming to ASTM E438 Type I, Class A for superior chemical resistance and thermal stability.
  • Strict control of maximum permissible thermal residual stress in accordance with ASTM E671 ensures safety and durability in laboratory use.

• Design and Dimensions

  • Uniform design specifications include circular cross-sections for necks and sidearms, spherical flask bottoms, and specified wall thickness.
  • Permanent marking requirements ensure clear identification of manufacturer and nominal capacity.

• Standardization Principles

  • The specification aligns with internationally accepted standardization practices, supporting consistency and compatibility across laboratories globally.

Applications

The ASTM E1405-98(2022) standard has widespread utility for industries and laboratories involved in:

• Petroleum Testing: Used for critical tests involving distillation of crude oils, road tars, turpentine, natural gasoline, and related products.
