Testing Service

Testing Services for Your Materials in China

If you source textiles, footwear materials, leather, or rubber from China, ensuring material performance before production is critical. At UNUO Instruments, we help international buyers and brands test and verify material performance directly at the source.

We provide comprehensive physical and chemical testing for footwear and textile materials to help you avoid quality issues and ensure compliance with international standards. ASTM, ISO, EN, GB, SATRA, etc.

Footwear Material Testing Services

We test upper materials, outsoles, leathers, linings, dynamic components, and hardware:

• Physical & Mechanical Performance:

  • Outsole abrasion resistance (DIN / Rotary Drum)

  • Flexing resistance (Ross, De Mattia, whole shoe flexing)

  • Upper-to-sole bonding strength and peel strength

  • Dynamic waterproofness & water absorption

  • Slip resistance (dry, wet, and ice surfaces)

  • Tear and tensile strength

  • Hardness, density, and compression set

• Chemical & Safety Testing:

  • Phthalates and plasticizers

  • Heavy metals (Lead, Cadmium, Chromium VI)

  • Cleavable carcinogenic AZO dyes

  • Formaldehyde content & pH value

  • Odor and volatile organic compounds (VOCs)

  • Zipper & hardware salt spray corrosion resistance

Textile & Fabric Testing Services

We cover woven fabrics, knits, linings, trims, and functional activewear materials:

• Physical & Functional Performance:

  • Tensile, tearing, and seam strength

  • Pilling resistance (Martindale / Circular Locus) & abrasion resistance

  • Dimensional stability (shrinkage) and appearance after washing

  • Hydrostatic pressure (waterproofness) & water vapor permeability (breathability)

  • Air permeability & quick-drying performance (wicking, absorption)

  • UV protection (UPF)

• Colorfastness & Chemical Testing:

  • Fastness to rubbing (dry/wet crocking)

  • Fastness to washing, water, and perspiration

  • Fastness to light and light-perspiration composite

  • Phenolic yellowing fastness

  • Fiber composition analysis & fiber ratio verification

  • Formaldehyde, pH value, and AZO dye screening
