Magnetic Field Strength and Performance Testing in Our Magnetic Therapy Fabric Testing Service

Surface magnetic flux density and field mapping per IEC 62233 and customer protocols — the magnetic field strength in gauss or millitesla is measured using a calibrated Hall-effect gaussmeter at multiple points across the fabric surface to verify the magnetic therapy fabric delivers the specified therapeutic field intensity and uniformity.
Magnetic field penetration depth and gradient measurement — the decay of the magnetic field with distance from the fabric surface is recorded to predict the depth of tissue penetration and the effective therapeutic range for the magnetic therapy fabric product.
Magnetic pole orientation and polarity verification — the arrangement of north and south poles on the fabric is mapped to confirm the intended alternating or unipolar magnetic pattern claimed in the product design.
Magnetic field stability under compression and stretching — the fabric is stretched, bent, or compressed while the magnetic flux density is monitored to verify the magnetic therapy fabric maintains its field properties during wear and body movement.
Magnetic field retention after environmental conditioning — the fabric is subjected to heat, humidity, and mechanical stress cycles, and the magnetic flux density is remeasured to confirm no permanent demagnetization occurs during transport, storage, and use.

Physical and Mechanical Property Testing of Magnetic Therapy Fabrics

Tensile strength and elongation at break per ISO 13934-1 and ASTM D5035 — the magnetic therapy fabric is pulled to failure in warp and weft directions to measure the breaking force and stretch, ensuring the embedded magnets do not cause premature tearing or fabric failure.
Tear strength per ISO 13937-2 and ASTM D1424 — the force required to propagate a tear is measured to guarantee the magnetic fabric resists damage from handling, washing, and daily wear.
Seam strength and magnet encapsulation integrity per ISO 13935-2 and customer protocols — the bond strength of stitched, welded, or laminated seams that enclose the magnets is tested to verify the magnets remain securely in place and do not detach during use or laundering.
Abrasion and pilling resistance per ISO 12945-2 and ASTM D4966 — the fabric surface is subjected to controlled rubbing to evaluate the durability of the magnetic therapy fabric against pilling, fuzzing, and surface wear from repeated contact with skin and bedding.
Bursting strength for knitted magnetic fabrics per ISO 13938-2 — for magnetic therapy fabrics used in compression garments and stretch applications, the multidirectional resistance to rupture is measured to ensure structural integrity.

Chemical Safety and Restricted Substance Compliance for Magnetic Therapy Fabrics

Heavy metals and toxic elements per EU RoHS and REACH Annex XVII — ICP-OES and ICP-MS analysis for lead, cadmium, mercury, and hexavalent chromium in the textile, magnetic coating, and any adhesive layers ensures the magnetic therapy fabric meets global consumer product safety limits.
Phthalates and plasticizers per CPSC-CH-C1001-09.4 and EN 14372 — GC-MS determination of the six restricted phthalates in any flexible plastic magnet encapsulation, backing film, or printed decoration on the magnetic therapy fabric.
Formaldehyde content and volatile organic compound emissions per ISO 14184-1 and ISO 16000-3 — cold water extraction and chamber emission testing verify the magnetic therapy fabric does not release harmful formaldehyde or VOCs into the indoor air or onto the skin during prolonged contact.
Azo colorants and restricted amines per EN 14362-1 — the fabric dyes are screened for banned aromatic amines to ensure the magnetic therapy fabric is free from carcinogenic azo colorants and safe for direct skin contact.
OEKO-TEX Standard 100 and eco-textile compliance — comprehensive screening for a wide range of regulated substances including pesticides, chlorinated phenols, and organotin compounds to certify the magnetic therapy fabric as harmless to human health.
Nickel release from magnetic and metallic components per EN 1811 — for magnetic therapy fabrics containing nickel-plated magnets or metallic threads, the nickel release rate is measured to verify it remains below the sensitization threshold for prolonged skin contact.

Biocompatibility and Skin Contact Safety Testing for Magnetic Therapy Fabrics

Skin irritation and sensitization testing per ISO 10993-10 and OECD 439 — the finished magnetic therapy fabric is tested on reconstructed human epidermis or under clinical conditions to confirm it does not cause erythema, edema, or allergic skin reactions during extended therapeutic use.
Cytotoxicity evaluation per ISO 10993-5 — extracts of the magnetic therapy fabric are applied to cultured cells to verify the material does not exhibit toxic effects, a fundamental safety requirement for medical and wellness textile devices.
Local effects after implantation for embedded magnet safety per ISO 10993-6 — for magnetic therapy fabrics with rigid encapsulated magnets, the biological response to any leachable substances is assessed to ensure no chronic inflammation or tissue damage occurs.
Microbial cleanliness and bioburden per ISO 11737-1 — the total viable count on the magnetic therapy fabric is measured to confirm the product meets hygiene standards for consumer and clinical use.

Durability, Washing, and Environmental Resistance Testing for Magnetic Therapy Fabrics

Dimensional stability and appearance after repeated laundering per ISO 6330 and AATCC 135 — the magnetic therapy fabric is subjected to multiple domestic and commercial washing and drying cycles, and the changes in dimensions, color, and surface appearance are measured to verify the product withstands routine care without shrinkage or distortion.
Magnetic field retention after simulated wash cycles — the magnetic flux density is remeasured after defined wash and dry cycles to confirm the magnetic therapy fabric retains its therapeutic performance throughout the claimed service life.
Color fastness to washing, perspiration, and rubbing per ISO 105-C06 and ISO 105-X12 — the magnetic fabric is tested for dye bleeding and color transfer to ensure the product does not stain the user's skin, other garments, or bedding during washing and wear.
Resistance to cosmetic lotions, oils, and sweat per ISO 175 and ASTM D543 — the fabric and magnet encapsulation are exposed to simulated body fluids and skincare products to verify no softening, swelling, or magnetic coating degradation occurs.
Thermal resistance and fire safety per 16 CFR Part 1610 and ASTM D6413 — the flammability of the magnetic therapy fabric is evaluated to ensure compliance with textile flammability regulations for general wearing apparel and bedding.
