When procuring tissue paper in bulk for an organization, most purchasing decisions are based on price, brand familiarity, or the word of a sales representative. Very few organizations ask to see actual lab test results.
This article shares what CENCLEAN's own independent test results show — and what every procurement officer should ask before placing a bulk tissue order.
Why CENCLEAN Submitted Tissue for Government Lab Testing
Before bringing products to market, CENCLEAN submitted samples for testing by Thailand's Department of Science Service (DSS), Ministry of Higher Education, Science, Research and Innovation — an independent government agency specializing in pulp and paper testing under Thai Industrial Standards (TIS).
The reason was not legal obligation — tissue paper standards are not mandatory in Thailand. The reason was simpler: organizational clients deserve verifiable data, not just marketing claims.
Actual Lab Test Results — Department of Science Service
Sample tested: CENCLEAN 2-ply Virgin Pulp Jumbo Roll Tissue, 5 rolls. Tested November 19–21, 2024. Reference standard: TIS 214-2560.
| Test Parameter | CENCLEAN Result | TIS 214-2560 Standard | Result |
|---|---|---|---|
| Basis Weight (g/m²) | 29.5 | ≥ 23.0 | ✅ Pass |
| Dirt Area (mm²/m²) | 1.5 | ≤ 6.0 | ✅ Pass |
| Dirt Count (points/m²) | 8 | ≤ 20.0 | ✅ Pass |
| pH Level | 7.9 | 5.5–8.5 | ✅ Pass |
What the results mean
Basis Weight 29.5 g/m² — 28% above the minimum standard of 23.0 g/m². High fiber density means the tissue is not thin or prone to tearing during use.
Dirt Area 1.5 mm²/m² — 75% below the maximum threshold of 6.0. Four times cleaner than the control limit, indicating clean raw materials and well-controlled production processes.
pH 7.9 — Near-neutral, close to human skin pH (7.4). Minimizes irritation risk on contact with skin. Particularly important for hospitals and healthcare facilities.
TIS 214-2560 — Not Mandatory, But More Important Than You Think
TIS 214-2560 is Thailand's industrial standard for tissue paper, issued by the Office of Industrial Product Standards (TISI). An important fact that many buyers don't know:
ℹ️ What most buyers don't know
TIS 214-2560 for tissue paper is not a mandatory standard in Thailand. Manufacturers are not required to obtain TIS certification to sell their products. This means the absence of a TIS mark does not automatically mean a product fails the standard — and the presence of a TIS mark does not guarantee everything. What matters most is verifiable test results from a credible laboratory.
What the Key Test Parameters Actually Mean
Basis Weight
Weight of tissue per unit area (g/m²). Too low means thin, fragile tissue that tears easily during use.
Cleanliness
Measures area and count of dirt spots per square meter — invisible contaminants such as fiber fragments, metal particles, or residue.
Water Absorption
Time for tissue to fully absorb water. Poor absorption means slower breakdown in plumbing — increasing blockage risk.
pH Level
Appropriate pH (5.5–8.5) reduces skin irritation risk. Critical for hospitals, operating rooms, and intimate hygiene use.
Tensile Strength
Resistance to tearing in both machine and cross directions. Low values mean tissue tears easily during normal use.
Ash Content
Inorganic material remaining after combustion. High ash indicates excessive use of fillers — reducing actual fiber quality and tissue performance.
5 Questions to Ask Any Supplier Before Ordering
- 1Do you have lab test results from an external laboratory — and is that lab a government agency or private?
- 2What standard was the testing conducted under — TIS 214-2560 or an equivalent ISO standard?
- 3Is the fiber Virgin Pulp or Recycled — both are acceptable, but the answer should match the price point.
- 4Can you provide documentation for tender submissions or ESG reporting?
- 5Can you issue e-Tax Invoice — for organizations requiring complete financial documentation?
A supplier who is confident in their product will answer all of these immediately — and have the documents ready.
