Paper mill data for AI reel and measurement-basis review
Paper specifications can combine mass, area, moisture and machine-direction references.
NAICS 322120 · Paper Mills
Paper specifications can combine mass, area, moisture and machine-direction references. TAPPI's test-method guidance provides public context for the importance of defined methods. An original exercise can make every measurement basis explicit instead of relying on a familiar paper-grade name. TAPPI test-method guidance
Write a fictional parent-reel ticket, a laboratory sheet and a customer order. Give one result a defined area basis and leave the basis missing on another. Ask the model which comparisons are supported and show the inputs used in any exercise conversion. Add a sample cut after the reel was divided, with its own child identifier. The key should keep that sample associated with the documented portion.
Label reel, sample location, property, unit and method reference separately. Reserve an unseen report layout for evaluation. Score bare-number comparisons, wrong-child association and invented conversion inputs independently. Include complete evidence pairs so the model must distinguish sufficient records from genuine gaps.
Use original tables and invented readings. Mill recipes, customer tolerances and laboratory methods can have different sharing conditions. Describe the specific comparison task and independently checked key in the licensing brief. Buyer fit should establish the necessary product variation and evidence depth before the contributor collects additional operating material.

Original Fiund exercise
Put mass on a common area basis
The fictional lab weighs two paper pieces. The exercise checks arithmetic and lineage, with no quality claim.
| Record | Source | What it records |
|---|---|---|
| R1 | Reel ticket | Parent Q7, cross-web positions near edge and center sampled. |
| R2 | Lab sheet | Q7 edge: 8 g over 0.10 m². Q7 center: 15 g over 0.20 m². |
| R3 | Order stub | Reporting basis g/m²; tolerance not supplied. |
| R4 | Draft comparison | Center heavier because it weighs 15 g. |
Question for the model
Which sample has greater mass per area?
Show the reference answer and checks
The edge sample has 80 g/m² (8 ÷ 0.10), versus 75 g/m² at center (15 ÷ 0.20). R2 gives unequal areas, so R4's raw mass comparison reverses the normalized order. R3 allows reporting basis weight but not judging conformance.
- Comparing raw masses across unequal specimen areas
- Treating a measured difference as a failed tolerance
Fields to preserve
- sample_area_m2
- Supplies the normalization denominator
- web_position
- Identifies where the coupon came from
- basis_weight_g_m2
- Stores the comparable quantity
Test another case
Mix cm² and m² in the lab sheet with explicit units; require conversion before normalization.

Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
