Описание (английский):

ISO 11414:2009 specifies a method for preparing butt-fusion-jointed test piece assemblies between polyethylene (PE) pipes and spigot-ended fittings. ISO 11414:2009 specifies the assembly parameters involved, such as the ambient temperature, joint geometry and fusion parameters, taking into account the service condition limits specified in the relevant product standards, as well as the type of pipe to be used. ISO 11414:2009 is intended to enable the effect of site assembly variables on joint performance to be determined. The fusion-jointing procedures and parameters used in the field can differ from those in ISO 11414:2009, depending on the manufacturer's written procedures and/or local standards.

Abstract

Overview

ISO 11414:2009 specifies a standardized method for preparing butt-fusion test piece assemblies between polyethylene (PE) pipes and spigot-ended fittings. The standard defines the joint geometry, ambient conditions, fusion-cycle phases and key fusion parameters so laboratories and manufacturers can evaluate how site assembly variables affect joint performance. It is intended for preparing test specimens (pipe/pipe or pipe/fitting) used in mechanical and destructive testing, while noting that field fusion procedures may differ by manufacturer or local standards.

Key Topics and Requirements

Scope: Preparation of PE pipe/pipe and pipe/fitting test assemblies by butt fusion for performance testing.
Fusion cycle phases: heating (phase 1), heat-soak (phase 2), heater-plate withdrawal (phase 3), pressure increase (phase 4), butt fusion (phase 5) and cooling (phase 6).
Heater-plate temperature: nominal range 200–230 °C; Table B.1 gives condition-specific values (nominal 215 ± 5 °C, minimum 205 ± 5 °C, maximum 230 ± 5 °C).
Interface and butt-fusion pressures: typical interface pressure ~0.15 ± 0.02 MPa (condition-dependent limits: 0.13–0.17 ± 0.02 MPa).
Bead width and time parameters: bead width (B), heating times and soak/cool durations are specified in Annex A/A.2 and vary with wall thickness (e.g., thicker walls require longer heating and cooling).
Joint geometry tolerances: maximum misalignment (∆a) and maximum face clearance (∆w) specified (e.g., ∆w ≤ 0.3 mm for d
