Описание (английский):

This document specifies the evaluation method of the environmental life cycle assessment (E-LCA) of ductile iron (DI) pipes used for water applications as specified in ISO 2531 and ISO 16631. This evaluation method, applicable to ductile iron pipe products, is based on concepts and methods developed in ISO 14040 and its application guidelines in ISO 14044.

Overview

ISO 4370:2022 - Environmental life cycle assessment and recycling of ductile iron pipes for water applications - specifies a standardized method to evaluate the environmental life cycle assessment (E‑LCA) of ductile iron (DI) pipes used in water systems (per ISO 2531 and ISO 16631). The method is based on the life cycle assessment framework of ISO 14040 and the requirements of ISO 14044, and focuses primarily on quantifying CO2‑equivalent (CO2e) emissions across all life cycle stages and on the role of recycling in reducing environmental impact.

Key technical topics and requirements

Scope and applicability

Applies to ductile iron pipe products for potable water and related water applications as defined in ISO 2531/16631.

E‑LCA fundamentals

Defines E‑LCA terms (functional unit, service life, reference service life - RSL, in‑use conditions) consistent with ISO lifecycle terminology.
Emphasizes quantifying environmental impacts, with a primary focus on CO2 emissions but noting applicability to other impact categories (e.g., eutrophication, acidification, resource depletion).

Life cycle stages and CO2 accounting

Provides methods and formulas to calculate total CO2e across: acquisition (manufacture and construction), operation (e.g., pumping energy), maintenance (leakage, repairs) and end‑of‑life.
Includes case calculations for different service‑life scenarios and time horizons.

Key drivers for impact reduction

Durability and reference service life (RSL), leakage rates, conveyance capacity, optimal wall thickness, mechanical properties, installation methods, and recyclability.

Recycling and annexes

Annex A: calculation methodology for CO2 accounting with provision for scrap recycling in DI pipe production.
Annex B: CO2 accounting for pump operation.
Annex C: scenario analyses comparing different ductile iron pipeline options.

Practical applications - who uses this standard

Water utilities and asset managers - for sustainable procurement, lifecycle planning and infrastructure replacement strategies.

Pipeline designers and civil engineers - to compare design options using consistent E‑LCA methods (e.g., sizing, material selection, installation methods).

Ductile iron pipe manufacturers - to quantify cradle‑to‑gate impacts, optimize manufacturing and recycling loops, and prepare Environmental Product Declarations (EPDs).

Environmental consultants and regulators - to support policy, ecolabelling, environmental claims and comparative lifecycle studies.

Procurement and sustainability teams - for strategic decision‑making, tender specifications and demonstrating reduced CO2 footprints.
