SGS test evidence
SGS Test Reports for Period Underwear Manufacturers
Use the SGS absorption and wash-durability reports as sample-level evidence for submitted period-underwear specimens. Results are tied to one construction, stated lab methods and the client's own >=20 mL absorption target; they do not certify every SKU, batch or material change.
These SGS documents are sample-level test reports, not product certifications. Report MCHGZ2601287-01A records 24 mL absorption after 1 pre-wash and after 52 pre-wash cycles against the client's >=20 mL target. It also records "No liquid leakage", the surface observation "There is red liquid on the touched surface" and a "/" single-item evaluation, so absorption is reported without a pass/fail conclusion. Report SL22602344377501TX records PASS conclusions for appearance after repeated home laundering and dimensional stability to washing.

| Document types | SGS Testing Reports |
|---|---|
| Absorption report | MCHGZ2601287-01A; job no. MNS260399GZ; SGS-CSTC Standards Technical Services Co., Ltd. Guangzhou Branch |
| Washing-durability report | SL22602344377501TX; SGS-CSTC Standards Technical Services (Qingdao) Co., Ltd. |
| Submitted sample | period underwear / knitted brief; buyer style reference withheld; color black |
| Absorption testing period | 2026-09-04 to 2026-09-10 |
| Washing testing period | 2026-08-26 to 2026-09-02 |
| Absorption result | 24 mL absorption after 1 pre-wash and after 52 pre-wash cycles, against the client's >=20 mL target within 12 hours |
| Absorption leakage observation | No liquid leakage was recorded for the no-external-force condition; the report also states: There is red liquid on the touched surface. The single-item evaluation is shown as /, not PASS. |
| Washing conclusion | Appearance after repeated home laundering: PASS; dimensional stability to washing: PASS. PASS here means the result met the client's requirement stated in the report, not a universal industry threshold. |
| 52-wash appearance result | Colour change 4; fabric pilling/fuzzing/matting 4-5; seam slippage 4-5; seam breakage 4-5; spirality 0.0% |
| 52-wash shrinkage result | Waistband -2.9%; hip -0.9%; out seam 0.0%; leg opening -3.7%; requirement +/-10% |
| Appearance rating note | For the overall appearance assessment, 5 = no or negligible change; 3 = moderate change; 1 = severe or distinct change. Pilling and colour-change notes should be read under their own report scales. |
| Sample composition note | Outside part 95% organic cotton + 5% spandex; waterproof layer 100% TPU; absorbing layer 100% polyester; inner skin-contact part 95% organic cotton + 5% spandex. |

Test method boundary
Test Conditions and Decision Basis
Keep these conditions beside the reports before a China-based OEM/ODM buyer quotes the result for a wholesale order.
| Absorption method | Client requirements: >=20 mL within 12 hours, no external force applied and no leakage allowed. Method: 12 drips, 2 mL per drip, 1 hour interval; sample conditioned at 20.0 °C and 65.0% RH for 24 hours. |
|---|---|
| Absorption pre-wash program | GB/T 8629-2017, Type A standard washing machine, 4N program, standard detergent 3, drying procedure A, 20 cm x 20 cm laundry bag. |
| Absorption note | The report notes the sample absorbs slowly; without applying external force, it takes about 4 to 5 minutes for the surface liquid to be completely absorbed autonomously. |
| Wash-durability methods | ISO 3759:2011, ISO 5077:2007 and ISO 6330:2021; horizontal-axis front-loading machine; Procedure No.3N; machine wash at 30 °C. |
| Wash load and drying | Total dry mass 2.0 +/- 0.2 kg with Type I 100% cotton ballast and specimen; 20 +/- 1 g ECE reference detergent 98 without optical brightener; tumble dry low, not exceeding 60 °C; washing in laundering bag. |
| Appearance method | ISO 15487:2018. |
| Decision basis | ILAC-G8:09/2019, Binary Statement for Simple Acceptance Rule, w = 0. |
| Accreditation note | The wash-durability report references CNAS L0604 and ILAC-MRA recognition. |

How Do You Read the Absorption and Wash-Durability Results Together?
The two reports use "52" for different mechanisms: pre-wash cycles before absorption testing, and home-laundering cycles in the durability test. Both remain sample-specific.
Sample boundary
Use Both SGS Reports with the Tested Sample and Method
Keep the two reports together: one covers absorption for the submitted buyer sample (style reference withheld), and one covers wash-durability for the submitted knitted brief. Neither report certifies every SKU, private label program, MOQ batch or changed construction.
Absorption test report
Report MCHGZ2601287-01A records 24 mL absorption after both 1 pre-wash and 52 pre-wash cycles, plus the surface-liquid observation and / evaluation.
Wash-durability test report
Report SL22602344377501TX records PASS for appearance and dimensional stability to washing; PASS means the client's stated requirement was met for this submitted sample.

Buyer FAQ
FAQ About the SGS Test Reports
These answers keep the reports tied to their actual sample and methods.
Are these SGS documents certifications?
No. They are testing reports for a submitted sample, not product certifications or factory certificates.
What absorption result can be quoted?
Under the absorption report conditions, the submitted sample showed 24 mL absorption after 1 pre-wash and after 52 pre-wash cycles against the client's >=20 mL target. The same file should also record the no-liquid-leakage condition, the red-liquid-on-touched-surface observation and the / single-item evaluation.
What washing-durability result can be quoted?
Under the washing-durability report conditions, appearance after repeated home laundering and dimensional stability to washing were both marked PASS; the 52-wash shrinkage values were within the stated +/-10% requirement.
Can these results be used for every product?
No. The reports relate to the tested sample. New styles, materials, construction changes, wash-care changes or market claims may require separate testing.
How do I verify these SGS reports for a China-based underwear supplier?
Scan the QR code printed on either report and check the report number at check.sgsonline.com.cn. Compare the verified result with the report number, sample and test conditions quoted here. Report MCHGZ2601287-01A was issued by SGS-CSTC Guangzhou Branch and report SL22602344377501TX by SGS-CSTC Qingdao, a CNAS L0604 and ILAC-MRA recognised laboratory. Verification confirms the document, not that the result applies to every SKU or batch.
