Full title and description

St ISO TR 10465-2-2007 — Underground installation of flexible glass‑reinforced pipes based on unsaturated polyester resin (GRP‑UP) — Part 2: Comparison of static calculation methods. This technical report compares the static design/calculation approaches (principally the ATV and AWWA procedures) used for buried GRP pipe installations and summarises key assumptions, load models and differences between the methods.

Abstract

ISO/TR 10465-2:2007 provides a focused comparison of established static calculation methods for the underground installation of flexible glass‑reinforced pipes made from unsaturated polyester resin (GRP‑UP). It explains and contrasts the ATV and AWWA procedures (and references other practices such as BS 9295), highlights soil‑load distribution, traffic loading, deflection and circumferential bending strain treatment, and clarifies where the procedures differ or may lead to different design outcomes. The report is intended as an informative guide to help designers, manufacturers and asset owners understand the practical differences and applicability limits of the calculation methods rather than to replace the original method documents.

Scope

The report compares static calculation methods for buried flexible GRP‑UP pipelines, summarising how soil loads, traffic loads, installation conditions and long‑term effects are represented in the different procedures. It is limited to explaining and contrasting key elements of the methods (not providing full derivations) so users can identify which procedure and assumptions are appropriate for a given installation. It does not replace the original standards, nor does it address jacking, relining, above‑ground installation, or site‑specific safety/regulatory matters.

Key topics and requirements

• Comparison of ATV and AWWA static calculation procedures (and notes on BS 9295).
• Soil‑load distribution concepts and the representation of initial and long‑term soil loads.
• Traffic loading models and their application differences between procedures.
• Deflection assessment: vertical deflection under loads and method limits.
• Circumferential bending strain evaluation and differences in calculation approach.
• Relevant symbols, abbreviations and typical parameter values used in the procedures.
• Guidance on applicability limits and when to consult original method documents for detailed calculations.

Typical use and users

Engineers and designers of buried pipeline systems, GRP pipe manufacturers, utilities and municipal water/wastewater authorities, installation contractors, standards committees and consultants use this report to understand differences between calculation methods and to inform specification, comparative design checks and technical discussions about safety factors, design assumptions and installation parameters.

Related standards

Companion and related publications include ISO/TS 10465‑1 (Installation procedures), ISO/TR 10465‑3 (installation parameters and application limits), system/product standards referenced by ISO 10465 (for example ISO 10467 and ISO 10639), and the external design procedures referred to in the report such as ATV A127, AWWA M45 and BS 9295. A previous edition (ISO/TR 10465‑2:1999) was withdrawn and the 2007 report superseded it.

FAQ

Q: What is this standard?

A: ISO/TR 10465‑2:2007 is a technical report that compares static calculation methods used for buried flexible glass‑reinforced polymer (GRP‑UP) pipes; it summarises and contrasts the ATV and AWWA design procedures and highlights key assumptions and differences.

Q: What does it cover?

A: It covers comparative treatment of soil and traffic loads, deflection and circumferential bending strain in static calculations for underground GRP‑UP pipes, and provides guidance on applicability and where methods diverge. It is informational — not a full method derivation — and directs users to the original procedure documents for detailed calculations.

Q: Who typically uses it?

A: Pipeline designers, structural and geotechnical engineers, GRP pipe manufacturers, utilities, installation contractors and standards committees use the report to inform design choices, specifications and comparative assessments between calculation methods.

Q: Is it current or superseded?

A: The report was published in September 2007 (Edition 1). It replaced the earlier 1999 edition. Users should check the latest ISO work programme or national standards bodies for any subsequent revisions or related work items (for example ISO work items to update or replace parts of the 10465 series may be in progress).

Q: Is it part of a series?

A: Yes — it is Part 2 of the ISO 10465 series on underground installation of flexible glass‑reinforced pipes (GRP‑UP). Related parts include Part 1 (installation procedures, published as ISO/TS 10465‑1:2007) and Part 3 (installation parameters and application limits, ISO/TR 10465‑3:2007), together with associated system/product standards.

Q: What are the key keywords?

A: Key keywords include GRP, GRP‑UP, glass‑reinforced pipe, unsaturated polyester, underground installation, static calculation, soil load, traffic load, deflection, ATV, AWWA, BS 9295.
