Overview

EN 14260:2003 is a European Standard developed by CEN that defines the characteristics and test methods for road tars derived from coal pyrolysis. These road tars-coal tar and pitch-based binders-are used in various industrial applications, primarily in road construction and maintenance. The standard specifies precise methods for evaluating critical properties of these materials to ensure quality, safety, and performance consistency.

Road tars are complex mixtures obtained through coal pyrolysis and vary by grade according to their intended use and desired end-product properties. This standard helps manufacturers, testing laboratories, and regulatory bodies assess these products systematically to meet industrial requirements and environmental safety.

Key Topics

• Scope and Classification
  EN 14260:2003 covers testing methods for road tars used in binders based on coal tar and pitch derivatives. It aligns with classifications provided in EN 13847:2001, categorizing road tars according to their chemical and physical properties.

• Characteristics to be Tested
  The standard outlines essential characteristics for testing road tars, including:

  • Water content
  • Density at 20 °C
  • Efflux time (viscosity indicator)
  • Distillation properties
  • Softening point and softening point of residual distillate at 300 °C
  • Needle penetration (penetration depth of a needle under specific conditions)
  • Content of naphthalene and anthracene fractions (important polycyclic aromatic hydrocarbons)
  • Flash point (evaluated using closed cup methods)
  • Dynamic viscosity profiles for modified road tars at temperatures between 80 °C and 120 °C

• Test Methods
  EN 14260 references standardized test procedures such as EN 1426, EN 1427, and ISO 2719, ensuring reliable and repeatable measurement across different laboratories. Detailed test protocols provide accuracy in determining each characteristic.

• Sampling Protocol
  Sampling and sample preparation are critical to achieving consistent test results. EN 14260 refers to ISO 6257 for guidance on collecting representative samples from bulk or containers, considering both liquid and solid forms of road tars.

• Safety and Handling Warnings
  Annex B includes safety guidelines on the handling, storage, and disposal of road tars. It provides first aid measures, explosion and fire hazard warnings, and environmental disposal recommendations compliant with regulatory requirements.

Applications

EN 14260:2003 is essential for professionals working in:

• Road Construction and Maintenance
  Ensuring road tars meet performance and safety standards for surface dressing, hot coated macadam, and other pavement applications.

• Industrial Manufacturing
  Quality control and product certification during production of coal tar-based binding agents, ensuring consistent material properties suited for industrial uses.

• Environmental and Safety Compliance
  Managing handling procedures and minimizing environmental risks through standardized testing of chemical components and hazardous fractions like polycyclic aromatic hydrocarbons.

• Research and Development
  Developing new formulations of road tar binders with improved durability, environmental footprint, or application performance by using benchmarked characteristics and test methods.

Related Standards

To fully comply with and complement EN 14260:2003, stakeholders should also refer to:

• EN 13847:2001 – Terminology and classification for coal tar and pitch based binders
• EN 1426 – Needle Penetration of bituminous binders
• EN 1427 – Softening Point determination (Ring and Ball method)
• EN ISO 2719 – Flash Point determination (Pensky-Martens closed cup)
• EN ISO 3838 – Density determination methods
• ISO 6257 – Sampling methods for carbonaceous materials in aluminum production
• EN 13357 – Efflux time of petroleum cut-back and fluxed bitumens

Implementing these complementary standards alongside EN 14260 ensures a comprehensive approach to the quality assessment and safe handling of coal tar-based road tars.
