Under-hood tape is specified by an abrasion class — and an abrasion class without its mandrel diameter is not a specification.
Abrasion results depend on the mandrel the test uses. The same tape measured on a 5 mm mandrel and a 10 mm mandrel gives different classes, which is why a drawing that names a class without the mandrel leaves suppliers free to quote whatever flatters them. The second variable is temperature: the grade that survives the bay may not survive the run that passes close to the manifold.
EJOY reads the drawing, confirms the class and mandrel it requires, and says plainly which evidence exists for the grade we quote. Process and laboratory detail is published by the manufacturer.

You have to re-source or dual-source a harness tape and the quotes you get back differ by 40% with no obvious reason. Here is the information that makes them comparable.
Read the guideThe drawing calls for an under-hood abrasion class and you need a tape quoted against it, with evidence an auditor will accept. Here is what to specify.
Read the guideHow this tape is made, and the test capability behind it, is published by the manufacturer: ONEI — PET Abrasion-Resistant Cloth Tape.
| Parameter | Value |
|---|---|
| Backing | Woven PET (polyester) cloth |
| Abrasion | Class C / Class D — the mandrel diameter is stated on the report |
| Temperature | up to 150 °C |
| Threads | ≈ 120–140/inch typical |
| Width | 9 / 15 / 19 / 25 / 32 mm |
| Adhesive | Hot-melt rubber / acrylic |
Standards: Abrasion grades to LV 312 Class C/D. A class is only comparable with the mandrel diameter it was measured on, so the report for the model quoted states both; grades to 150 °C.
Where this grade sits in LV 312: Copy the abrasion class and the mandrel diameter straight from the drawing into the request for quotation. That one line removes most of the spread between quotes, because a class quoted on a different mandrel is a different severity wearing the same letter.
Reading this table: each row is the range available across the constructions on this page, not a set of values that coexist in one roll. Backing, adhesive, temperature class and width are fixed together per model, so ask us to confirm one construction rather than combining rows.
Because the abrasion class is measured against it. A result on a 10 mm mandrel and one on a 5 mm mandrel describe different severities, so two quotes can cite the same class and mean different things.
Sometimes, but it is often the expensive answer. Zoning — a higher class only where the loom rubs or runs hot — usually costs less and wraps faster. Send the routing and we propose the zones.
No. They are separate requirements with separate evidence. If the routing sees oil or hydraulic fluid, name the fluid, the temperature and the contact time in the RFQ.
The real cable, the real bundle diameter and the real contact geometry, before and after your thermal cycle — abrasion failures usually start where the loom crosses an edge.
