What Is TS EN 14229? What the Standard Means for Wooden Poles
·
TS EN 14229 appears in many power and telecom specifications: it sets how a wood pole is defined and compared. Here is what it means for buyers.
Specifications for power distribution and telecom projects often name TS EN 14229 for wooden poles. The standard gives a common language for how overhead line wood poles are described, what properties they must have and how they are compared. The "TS" prefix shows that the European standard EN 14229 has been adopted as a Turkish Standard.
What is TS EN 14229, and why does it matter?
Wood is a natural material: two trees of the same species differ in thickness, straightness and defects. Without a common standard, "a 10 m pole" can mean different things to buyer and producer. By defining sizes, how they are measured and the acceptance limits, the standard removes disputes at order and delivery and makes poles from different producers comparable.
Main topics of the standard
- Dimensions and taper: a wood pole thins from butt to top. The standard sets the top, middle and butt diameter ranges by length and class, and how the taper is calculated.
- Classes: poles of the same length are grouped by thickness; our products mark them H (light), O (medium) and A (heavy).
- Visible characteristics: limits for knots, bow, splits and similar defects keep out poles whose strength would suffer.
- Durability: requirements for the protective treatment of poles set into the ground.
- Marking and records: so the length, class and producer of a pole can be traced.
Length and class read together
A pole is named by length and class: "10-O" is a 10 m medium-class pole. H, O and A poles of the same length differ in top and butt diameter; the heavy class is thicker to carry more load at corners and tension points. See the diameter table in our article on wooden electricity pole sizes.
What it means for buyers
- Match the specification: write the required length and class into the order exactly.
- Check at delivery: diameters can be measured at the points the standard describes.
- Ask for documents: mention any documents your project requires; see quality and certificates.
In our production
The taper of our wood poles is calculated to TS EN 14229, and we produce classes H, O and A in 9, 10, 11 and 12 m lengths. Pine logs are peeled, dried and impregnated under vacuum and pressure. The technical tables of our electricity, telephone and wire poles are on their product pages. Send length, class and quantity through the quote form.
