Abstract
Overview
ISO 4142:2002 specifies a range of laboratory test tubes suitable for general laboratory use. The standard distinguishes three material types - Type I (borosilicate), Type II (neutral glass) and Type III (soda‑lime glass) - and defines requirements for material, construction, marking and dimensions. ISO 4142:2002 helps laboratories and manufacturers ensure consistent quality, interchangeability and appropriate chemical and thermal performance for routine lab work.
