What is ISO 4803 about?
ISO 4803 specifies requirements for borosilicate 3,3 glass tubing for laboratory apparatus in an outer diameter range from 4 mm to 300 mm.
ISO 4803 defines dimensions, material, denomination, designation, requirements, and inspection methods.
Who is ISO 4803 for?
ISO 4803 on laboratory glassware borosilicate glass tubing is useful for:
- Quality control laboratories
- Borosilicate glass manufacturers and suppliers
- Food, Chemical and Pharmaceutical industries
Why should you use ISO 4803?
Borosilicate glasses show properties such as a very high hydrolytic resistance, a very high acid resistance and a medium alkali resistance. Borosilicate glasses can contain alkali earths or be free of alkali earths.
These special characteristics make this glass preferable for technical purposes with high chemical and thermo shock resistance. The field of application is mainly laboratories for chemical, pharmaceutical and food industries as well as other technical applications where these properties are needed.
ISO 4803 provides dimensions, material, denomination, designation, requirements and inspection methods which helps you to produce standardized products for technical purpose
What’s changed since the last update?
BS ISO 4803:2021 supersedes BS 5895:1980, which is withdrawn. BS ISO 4803:2021 includes some technical changes with respect to BS 5895:1980. These include:
- Update of the dimensions and tolerances
- Inclusion of a comprehensive and precise description of the mentioned quality characteristics and determination methods
