SIZES AND TOLERANCES
Product catalog summary
Specifications and Tolerances:
The document outlines the specifications and tolerances for honed internal diameters (I.D.), outer diameters (O.D.), wall thickness (W.T.), and mass per meter for various sizes of tubes. The tolerances for O.D., W.T., and outside straightness adhere to the EN 10297-1 standard, while the I.D. tolerances follow the H8 tolerance class as per EN 20286.

Key Measurements:
- I.D. Honed: Ranges from 60 mm to 105 mm with specific tolerances of -0/+0.046 mm for most sizes, and -0/+0.054 mm for larger diameters.
- O.D.: Varies from 76.1 mm to 177.8 mm depending on the I.D. size.
- W.T. Raw: Wall thickness ranges from 1.6 mm to 45.0 mm.
- Mass Raw: Mass per meter ranges from 13.4 kg/m to 147.0 kg/m.
Summary of Data:
The document provides a detailed table of measurements for each I.D. size, listing the corresponding O.D., W.T., and mass. This data is crucial for ensuring compliance with the specified standards and for applications requiring precise dimensional tolerances.

Catalog excerpts
O.D., w.t. and outside straightness follow the tolerances stated by the norm EN 10297-1. The tolerances on the I.D. are ruled by tolerance H8 according to EN 20286 instead, as resumed here below.
