Overview
ISO/TR 5102:2025 is a Technical Report from ISO that analyses and compares existing regional and national standards for fibre-reinforced plastic (FRP) working towers made of prefabricated elements. It does not set new prescriptive requirements itself; instead, it identifies the main differences across standards (Europe, UK, USA, China, Australia/New Zealand, Russia, South Africa, Malaysia, Singapore, Japan, etc.) to support the future development of a harmonized international standard for FRP work towers.
Key topics and technical coverage
This guidance document examines and summarizes differences in the following technical areas:
- Product title and scope – how jurisdictions name and classify FRP working towers and modular prefabricated systems.
- Grade division and material performance – approaches to performance grading, mechanical and durability expectations for FRP components.
- Dimension requirements – dimensional rules and module geometry used for interchangeability and safe use.
- Product structure and design – typical prefabricated element designs, assembly concepts and structural considerations specific to FRP.
- Test methods – comparison of regional test procedures used to verify strength, stability and component performance.
- Fall prevention measures – mandated or recommended collective and personal fall protection provisions associated with tower use.
The report highlights variations in terminology, grading systems, test protocols and safety provisions, providing a clear map of areas needing alignment for a global standard.
Practical applications and who uses this standard
ISO/TR 5102:2025 is a reference tool for stakeholders involved with FRP prefabricated work towers, including:
- Manufacturers and product designers - to understand regional differences in performance expectations and testing when exporting or designing for multiple markets.
- Testing laboratories and conformity assessors - to align test programs and interpret differing regional requirements.
- Regulators and standards developers - to identify conflicts and convergences for drafting harmonized international requirements.
- Procurement, safety managers and end users - to compare product compliance claims and select appropriate systems for sensitive environments.
- Specialist sectors - such as glazing, heritage building maintenance, aviation, electrified rail and explosive/flammable environments where non-conductive, lightweight towers are preferred.
Related standards and next steps
ISO/TR 5102:2025 is preparatory guidance intended to inform the future work of ISO/TC 61 on creating an international standard for FRP prefabricated work towers. Users should consult national standards bodies and referenced regional standards when applying the report’s findings in design, testing or procurement decisions.
