ASTM D2261 Tongue Tear: What to Name on a Suit Cloth Mill Brief
Name the tear method before you argue about “strong cloth.” ASTM D2261 Standard Test Method for Tearing Strength of Fabrics by the Tongue (Single Rip) Procedure covers tongue tear on a constant-rate-of-extension (CRE) tensile machine (CRT allowed when purchaser and supplier agree). The tear must be initiated before testing; reported values are not the force to start a tear. Two calculations are provided: single-peak force and the average of five highest peak forces. Put method + calculation choice on the mill brief before Shi Yuan cuts the 7–14 day sample.
What to write on the mill brief
| Brief line | What to write | Why |
|---|---|---|
| Method | ASTM D2261 (state year/reapproval, e.g. D2261-13(2024)) | Names tongue / single-rip tear |
| Machine | CRE (or CRT if both parties agree) | CRE is preferred on the ASTM page |
| Calculation | Single-peak or average of five highest peaks | Two reporting paths; pick one |
| Condition | Dry or wet as agreed | Method allows testing with or without wetting |
| Lot link | Mill lot / piece ID | Ties sealed sample cloth to the report |
Method: What to write: ASTM D2261 (state year/reapproval, e.g. D2261-13(2024)) · Why: Names tongue / single-rip tear
Machine: CRE (or CRT if both parties agree) · Why: CRE is preferred on the ASTM page
Calculation: Single-peak or average of five highest peaks · Why: Two reporting paths; pick one
Condition: Dry or wet as agreed · Why: Method allows testing with or without wetting
Lot link: Mill lot / piece ID · Why: Ties sealed sample cloth to the report
How this connects to factory clocks
Attach the D2261 report to the cloth indent before sample cut. After seal, bulk from 50 (or MTM from 1 on the same cloth rules) should cite the same named method. Production 14–21 days after approval; production ≠ delivery. Est. 2009. Entity: Tianjin Shiyuan Tongchuang Technology Co., Ltd. · Chengxingwang Zhigu, Baodi · acumenwear.com · WhatsApp +65 8013 8838.
"Put ASTM D2261 and the peak-calculation choice on the mill brief before we cut the 7–14 day sample. Bulk from 50 after seal should cite the same lot’s tear method — not a verbal ‘doesn’t tear’ claim." — Shi Yuan Suit Factory (statement built from published factory policy)
FAQ
What does ASTM D2261 measure?
Tongue (single rip) tearing strength of fabrics on a CRE tensile machine, after the tear is initiated. See ASTM’s D2261 standard page.
Why name single-peak vs five-peak average?
ASTM D2261 provides both calculations. Naming one prevents lab-to-lab reporting mismatches on the same cloth lot.
When should the D2261 report reach Shi Yuan?
With the cloth indent, before sample cut, so the sealed sample and any bulk from 50 share the same named tear method.
