Overview

SIST EN 1595:2000 is a European standard developed by CEN that establishes general rules for the design, manufacture, and testing of pressure equipment made from borosilicate glass 3.3. This standard specifically addresses equipment such as vessels, pipes, and valves that utilize borosilicate glass with a mean linear thermal expansion coefficient of (3.3 ± 0.1) x 10⁻⁶ K⁻¹. It defines comprehensive requirements for materials, inspection processes, testing protocols, and marking to ensure safety and reliability in industrial applications. Notably, this standard excludes certain glass products like circular, flat, and tubular sight glasses and equipment made from borosilicate glass with different thermal expansion coefficients.

Key Topics

• Material Specifications
  Defines the precise characteristics of borosilicate glass 3.3, including thermal expansion properties crucial for pressure resistance under varying temperature conditions.

• Design Principles
  Provides general rules for the safe and effective design of pressure vessels and associated components, emphasizing dimensional stability and structural integrity when subjected to pressure and thermal stresses.

• Manufacturing Guidelines
  Outlines recommended manufacturing procedures to maintain the mechanical and chemical properties of borosilicate glass during fabrication of pressure equipment.

• Inspection and Testing
  Details required inspection methods and testing techniques to verify compliance with mechanical strength and safety criteria, including pressure testing and defect identification.

• Marking Requirements
  Specifies marking protocols to ensure traceability and identification of compliant pressure equipment throughout its lifecycle.

Applications

SIST EN 1595:2000 is essential for industries where pressure vessels made from borosilicate glass 3.3 are used, including:

• Chemical and Pharmaceutical Manufacturing
  Reaction vessels and pipelines requiring resistance to thermal shock and chemical corrosion.

• Food and Beverage Processing
  Transparent pressure equipment allowing visual monitoring while maintaining high safety standards.

• Laboratory Equipment Production
  Fabrication of specialized containers and apparatus designed to withstand internal pressure and variable temperatures.

• Industrial Process Engineering
  Installation of borosilicate glass components in chemical reactors, distillation columns, and storage vessels where durability and visibility are critical.

Related Standards

• EN 13445 – Unfired Pressure Vessels: Provides design and manufacturing rules for metal pressure vessels, complementary to glass equipment standards.
• EN 1092 – Flanges and Their Joints: Details standards on flanges often used alongside borosilicate glass pressure components.
• ISO 9001 – Quality Management Systems: Relevant for manufacturers implementing consistent quality control processes for compliance.
• EN 10204 – Metallic Products Inspection Documents: Related to inspection documentation which may guide marking and certification practices.

By adhering to SIST EN 1595:2000, manufacturers and users of borosilicate glass pressure equipment can ensure optimal safety, quality, and performance in a variety of demanding industrial environments. This standard plays a critical role in improving product reliability while facilitating regulatory compliance across European markets.
