Our Product Testing Protocol
We perform around 20 tests to produce our top-quality and reliable planners, notebooks, and Journals, etc. They are listed below.
| Items | Description |
|---|---|
|
REACH (EC 1907/2006) – Annex XVII |
This test ensures our journals and albums are safe by restricting the presence of harmful chemicals (like specific dyes or lead) in materials such as paper, ink, leather, and coatings. It guarantees compliance with the strict chemical safety regulations of the European market. |
|
ASTM F963-17 |
This evaluation checks if the product meets U.S. safety requirements for heavy metal content and physical hazards. It helps ensure safe use by minimizing health risks from materials. |
|
pH Test for Paper ISO 6588 (Acidity Test) |
This test verifies that the paper in our products is acid-free or pH-neutral, preventing pages from yellowing and becoming brittle over time. It ensures your written memories and photos will be preserved for years to come. |
|
Writing Performance & Ink Bleed-through Test (ISO 3783:2006, ISO 2471:2008) |
We evaluate how smoothly our paper performs with various pens (gel, fountain, marker) and its resistance to ink bleeding or feathering. This ensures a superior, frustration-free writing experience for the end user. |
|
Physical Performance Tests |
Measure the paper’s durability – how well it resists tearing, pulling, or folding under pressure. They ensure the journal withstands daily use and maintains its structure over time. |
|
Lay-Flat Binding |
Thread-bound or screw-post design allows 180° lay-flat use. |
|
Closure & Accessories |
Elastic bands, ribbon markers, and pen loops integrated seamlessly. |
|
Leather Thickness |
Typically uses full-grain leather with a thickness ranging from 1.2 mm to 1.5 mm (for cow leather). |
|
Paper GSM |
Available in 80, 100, or 120 gsm acid-free, ivory-colored paper to prevent ghosting and bleed-through. |
|
Tensile Strength |
≥15 MPa (for cow leather used in covers). |
|
Tear Resistance |
≥30 N/mm (ensures durability for frequent use). |
|
Seam Strength |
Stitching and binding withstand ≥29.4 N load (tested per QB/T 4874 for seam fatigue resistance) |
|
Azo Dye Free |
Azo Dye Free: Complies with ISO 17234-1 and ISO 17234-2, prohibiting harmful azo dyes. |
|
Formaldehyde Content |

|
Abrasion Resistance |
Abrasion Resistance: ≥1,000 cycles (CS-10 wheel, 1kg load) for covers (QB/T 2726) |
|
Color Fastness |
Color Fastness: ≥4/5 (dry) and ≥3/5 (wet) on rubbing tests (QB/T 2537) |
|
Water Resistance |
Surface treatment ensures water penetration pressure ≥10 kPa (ISO 17230) |
|
