Описание (английский):

This document specifies a method for the preparation of test pieces assembled from polyethylene (PE) pipes or spigot-ended fittings and electrofusion fittings (e.g. socket fittings such as couplers, or saddles). The assembly criteria specified include parameters such as ambient temperature, fusion conditions, fitting and pipe dimensions, pipe configuration (coiled or straight pipe), taking into account the limiting service conditions specified by the relevant product standards. This document can apply to other shapes, e.g. re-rounded pipes, dependent on the manufacturer's instructions. NOTE For the purpose of this document, PE is understood to be PE, PE-RT or PE-X.

Abstract

Overview

ISO 11413:2019 specifies a standardized method for preparing test-piece assemblies between polyethylene (PE) pipes (or spigot-ended fittings) and electrofusion fittings (for example socket couplers and saddles). It defines how to condition, dimension, prepare and joint test specimens so that subsequent mechanical and performance tests are reproducible and consistent with relevant product standards. Note: for this standard, PE covers PE, PE‑RT and PE‑X.

Key topics and technical requirements

Scope of assemblies: Applies to PE pipes, spigot-ended fittings and electrofusion fittings (sockets, couplers, saddles); also adaptable to other shapes (e.g., re-rounded pipes) per manufacturer instructions.
Dimensional symbols and clearances: Defines mean diameters, fusion-zone dimensions and clearances between fitting bores and pipe outside diameters (see Annex A). For saddles the clearance is assumed zero.
Surface preparation / scraping: Minimum scraping depth is 0.2 mm unless the fitting manufacturer specifies a greater depth; scraping may be omitted where allowed.
Ambient temperature and reference conditions: Reference ambient temperature is (23 ± 2) °C. Jointing must account for permitted ambient range Tmin to Tmax and fusion energy adjustments with temperature (Annex B diagrams).
Conditioning periods: Assemblies must be conditioned at the test ambient temperature before fusion. Minimum periods depend on nominal wall thickness (examples from the standard: e
