Pure polyester testing service

Pure Polyester Testing Service for Global Textile and Material Markets

As an ISO/IEC 17025 accredited laboratory, we deliver a comprehensive pure polyester testing service that verifies fiber composition, mechanical performance, thermal stability, color fastness, chemical safety, and long-term durability. Our pure polyester testing service supports manufacturers and exporters of polyester staple fibers, filament yarns, woven and knitted fabrics, nonwovens, films, and polyester-based plastic articles who must demonstrate conformity to ISO, ASTM, EN, and regional textile and consumer product regulations across the European Union, North America, the Middle East, and Asia. Every test is conducted under our CNAS-accredited quality system, producing reports accepted by notified bodies, customs authorities, and procurement teams worldwide.

Physical and Mechanical Performance Testing in Our Pure Polyester Testing Service

Tensile strength and elongation at break per ISO 13934-1, ASTM D5034, and ISO 527 — for fabrics, films, and plastic specimens, the breaking force and stretch are measured in machine and cross directions to ensure the pure polyester material withstands processing, tension, and end-use mechanical loads.
Tear strength and puncture resistance per ISO 13937-2, ASTM D1424, and ASTM D5748 — the force required to propagate a tear or pierce the material is quantified to verify the pure polyester fabric or film resists damage from sharp objects and handling.
Seam slippage and seam strength per ISO 13936-2 and ASTM D1683 — for pure polyester woven fabrics, the resistance of sewn seams to opening under load is evaluated to guarantee durability in garments and upholstered furniture.
Bursting strength and ball burst per ISO 13938-2 and ASTM D3786 — for knitted and nonwoven pure polyester materials, the multidirectional resistance to rupture is measured to confirm structural integrity under multidirectional stress.
Stiffness, drape, and handle properties per ISO 4604 and ASTM D1388 — the flexural rigidity and bending length are measured to assess the fabric hand and suitability for garment and drapery applications.
Abrasion resistance by Martindale and Taber methods per ISO 12947-2 and ASTM D3884 — the resistance of pure polyester fabrics and coatings to surface wear and pilling is evaluated to predict appearance retention after prolonged use and washing.
Dimensional stability and shrinkage in hot air and water per ISO 6330 and ASTM D1204 — the pure polyester material is subjected to washing, drying, and heat exposure cycles, and the percentage dimensional change is recorded to verify it meets the manufacturer's claims and end-use requirements.

Thermal, Optical, and Weathering Testing for Pure Polyester

Melting point, glass transition, and crystallinity by differential scanning calorimetry per ISO 11357-3 and ASTM D3418 — the thermal transitions of the pure polyester resin or fiber are measured to confirm the polymer grade and to predict processing behaviour in extrusion, molding, and heat setting.
Thermogravimetric analysis for composition and thermal stability per ASTM E1131 — the mass loss profile up to 600 °C quantifies the volatile content, filler level, and decomposition temperature, verifying the purity of the polyester material.
Heat resistance and hot air aging per ISO 188 and ASTM D573 — pure polyester films, fabrics, and coatings are aged at elevated temperatures and the retained mechanical properties are measured to predict service life in high-temperature environments.
Accelerated weathering by xenon-arc exposure per ISO 4892-2 and ASTM G155 — the colour change, gloss loss, and tensile strength retention of pure polyester textiles and coatings are evaluated after simulated sunlight and rain cycles to validate outdoor durability.
Haze, gloss, and total luminous transmittance per ASTM D1003 and ISO 2813 — for pure polyester films and transparent articles, the optical clarity and surface reflectance are measured to meet packaging and display specifications.

Color Fastness and Chemical Compatibility Testing for Pure Polyester

Color fastness to washing, water, perspiration, and dry cleaning per ISO 105-C06 and ISO 105-E01 — the dyed pure polyester fabric is subjected to simulated laundry and contact conditions, and the staining and color change are graded to ensure the product retains its appearance throughout its service life.
Color fastness to light and xenon arc per ISO 105-B02 — the resistance of the pure polyester dyeing to fading under intense light is assessed and rated against the blue wool scale for indoor and outdoor applications.
Resistance to solvents, oils, and acids per ISO 175 and ASTM D543 — the pure polyester material is immersed in a range of industrial and household chemicals to verify no softening, swelling, or dissolution occurs in the intended service environment.
Migration and extractables for food contact applications per EU Regulation 10/2011 and FDA 21 CFR — pure polyester films, coatings, and plastic articles are tested for overall migration and specific migration of monomers, oligomers, and additives to confirm safety for direct food contact.
Stain resistance and cleanability per EN 12720 and internal protocols — for pure polyester textiles and coated surfaces, the ease of removal of common household stains is evaluated to support performance claims.

Chemical Safety and Restricted Substances Compliance for Pure Polyester

RoHS compliance per IEC 62321 and EU Directive 2011/65/EU — quantitative screening for lead, mercury, cadmium, hexavalent chromium, PBBs, and PBDEs in pure polyester resins, colorants, and any electronic or metallic attachments to ensure the product meets substance restrictions for the destination market.
Phthalates and plasticizers per CPSC-CH-C1001-09.4 and EN 14372 — GC-MS determination of the six restricted phthalates in any flexible components or printed coatings applied to pure polyester substrates, ensuring compliance with children's product safety regulations.
Formaldehyde and volatile organic compound emissions per ISO 14184-1 and ISO 16000-3 — cold water extraction and chamber testing verify that pure polyester textiles and films do not release harmful levels of formaldehyde or VOCs into indoor air, a requirement for OEKO-TEX and green building certification.
Azo colorants and restricted aromatic amines per EN 14362-1 — the pure polyester fabric or yarn is screened for banned azo dyes that could release carcinogenic amines, ensuring the product is safe for direct skin contact.
Heavy metals in packaging per EU Directive 94/62/EC — verification that the sum concentration of lead, cadmium, mercury, and hexavalent chromium in the packaging materials used to protect the pure polyester product is below the 100 ppm regulatory limit.
Antimony content and migration from PET materials per EN 71-3 and EU Regulation 10/2011 — for polyester food contact articles, the antimony catalyst residue and its migration into food simulants are quantified to ensure compliance with health-based limits.
