Описание (английский):

ISO 3126:2005 specifies methods for measurement and/or determination of the dimensions of plastics pipes and fittings and the accuracy of the measurement. It specifies procedures for measuring angles, diameters, lengths, squareness and wall thicknesses for the purposes of checking conformity to geometric limits.

Overview

EN ISO 3126:2005 - Plastics piping systems: determination of dimensions specifies standardized methods to measure and report the geometric dimensions of plastic pipes and fittings. It defines how to measure angles, diameters, lengths, end squareness and wall thicknesses and sets requirements for measurement accuracy, instruments, calibration and test conditions for conformity checks against geometric limits.

Key topics and technical requirements

Scope and purpose

Procedures for checking conformity of plastic piping components to geometric limits (angles, diameters, wall thickness, lengths, out‑of‑roundness, squareness).
Metric units are used; methods can be applied to other units with correct conversion.

Measuring devices and calibration

Distinguishes contact (micrometer callipers, vernier callipers, tube micrometers, π‑tape, go/no‑go gauges) and non‑contact (optical or ultrasonic scanners) instruments.
Instruments must be calibrated regularly and traceable to an accredited reference standard.
Contact surfaces must meet hardness and geometry requirements to avoid deformation.

Test conditions

Measurements should be made at (23 ± 2) °C or results correlated to that temperature.
Inspect surfaces for mould lines, marks or defects that could affect readings and record their influence.
Select cross‑sections per the referring standard or manufacturer’s instructions (normally ≥ 25 mm from ends).

Accuracy and rounding

Defined accuracy/tolerance requirements for wall thickness and diameter measurements (examples extracted from the standard):
- Wall thickness required accuracy: ≤10 mm → individual result ±0.03 mm; mean rounded to 0.05 mm.
- Diameter measurement accuracy: DN ≤600 → individual result ±0.1 mm; mean rounded to 0.1 mm.
Minimum number of readings: e.g., at least six wall‑thickness measurements around a section to compute arithmetic mean.

Special fittings

Procedures for measuring bends, branches, reducers, flanges and collars, including bolt hole distribution, pitch circle diameter and flange thickness.

Practical applications

Quality control and production inspection - Routine dimensional checks on pipe and fitting batches to ensure conformance to product specifications.

Type testing and certification - Verifying geometric conformity for standards compliance and certification dossiers.

Incoming inspection and supplier acceptance - Using go/no‑go gauges and calibrated instruments to accept or reject components.

Design validation and R&D - Accurate dimensional data for prototype verification and tooling adjustments.

Site verification - Checking spigot/socket fit, squareness and flange alignment during installation.
