Dimensional change of textiles as a result of washing and drying

This test is a combination of two testing standards that are used to assess the dimensional changes in textiles and clothes after a dry cleaning process. The results are expressed as percentages (%) of either extension (+) or shrinkage (–). ISO 3175-1 Professional care, dry cleaning, and wet cleaning of fabrics and garments – Part 1: Assessment of performance after cleaning and finishing ISO 3759, Textiles – Preparation, marking, and measuring of fabric specimens and garments in tests for determination of dimensional change.

This test is a combination of two standards that are together used to determine dimensional changes in textiles and clothing after ironing. The results are expressed as percentages (%) of either extension (+) or shrinkage (–). DIN 53894-1 – Determination of dimensional change of textile fabrics, ironing with a moist ironing cloth on an ironing press. ISO 3759, Textiles – Preparation, marking, and measuring of fabric specimens and garments in tests for determination of dimensional change.

Determination of certain aromatic amines derived from azo dyes in accordance with the standard EN 14362-1.

This test measures the air permeability of fabrics according to standard EN ISO 9237. Most types of fabrics, including industrial fabrics for technical purposes, nonwovens, and made-up textile articles, are suited for the test. The result will be given in l/m²/s, expressing the amount of air that passes through a square meter of fabric in one second.

This test determines the distortion of a woven fabric in which the weft yarns are perpendicular to the warp yarns.

This test is used to detect optical brighteners with UV light according to an in-house method. Optical brightening agents (OBAs) are often added to fabrics by manufacturers to increase their perceived whiteness or brightness.

IMO 2010 FTP Code Part 8 testing for upholstered furniture is used to assess the suitability of materials for maritime use. The results can be used for type approval (wheel mark). The testing is performed on the actual product or a small-scale test chair consisting of the cover and filling components of the product. Materials needed for the test are as follows x 3: Cover: 800 mm x 650 mm, Back-filling: 450 mm x 300 mm x 75 mm , Seat-filling: 450 mm x 150 mm x 75 mm. During the cigarette test, a cigarette is lighted and positioned axially along the junction between the seat and the back. The test assembly is not allowed to smolder after one hour from the beginning of the test. In the burner tube test, a burner tube with a propane flame is allowed to burn for 20 seconds, positioned axially along the junction between the seat and the back. No flaming or progressive smoldering is allowed to continue for more than 120 seconds after the removal of the burner tube.

We offer comprehensive test packages for verifying the quality of type II and type IIR face masks according to the EN 14683 standard. The tests included in the packages are required to label face masks with the CE marking. Medical face masks are divided into Types I and II according to their bacterial filtration efficiency. Type I masks are not intended for healthcare professionals, but for the public to prevent the spread of infectious diseases. Type II masks are further classified based on whether they are splash-resistant (Type IIR) or not (Type II). To comply with the European Standard EN 14683, Type II face masks must undergo the following quality tests: Bacterial filtration efficiency (BFE) - The ability of the face mask to filter the bacterium Staphylococcus aureus. The BFE is expressed as the percentage of colony-forming units (cfu) that have passed via aerosol through the facemask. If a face mask consists of two or more areas with different characteristics, these areas will be tested separately., Breathability (Differential pressure) - The amount of differential pressure required to draw air through a measured surface area at a constant flow rate., Microbial cleanliness (Bioburden) - The measurement of colony forming units per gram as per EN ISO 11737-1., Biocompatibility - The medical face mask manufacturer shall complete a biocompatibility evaluation according to ISO 10993-1 as a surface device with limited contact. The applicable toxicology testing regimen shall also be determined.. In addition to the above, Type IIR masks require the following test: Splash resistance - Performed according to ISO 22609, this test determines the ability of a face mask to resist penetration of splashes of liquid at different pressures.. The lower displayed price applies to the Type II mask test package, while the higher price also includes the splash resistance test required for Type IIR masks.

Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. They have also been used as additives in products such as cosmetics and personal care items. Several phthalates have been identified as endocrine-disrupting agents or as chemicals toxic to reproduction. Exposure to phthalates can occur through: Oral exposure Food: Exposure occurs via migration from food packaging., Children's toys: Children often put toys in their mouths.., Inhalation: Breathing in dust from vinyl flooring or fragrances (like perfumes) can cause exposure to phthalates via inhalation., Skin contact: Phthalates present in cosmetics, lotions, and soaps can be absorbed through the skin.. For other listed matrices apart from cosmetics, the analysis package covers the following substances included in the REACH Authorization List: Substance Abbreviation CAS number Diisobutyl phthalate DIBP 84-69-5 Dibutyl phthalate DBP 84-74-2 Benzyl butyl phthalate BBP 85-68-7 Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Di(n-octyl) phthalate DNOP 117-84-0 Diisononyl phthalate DINP 68515-48-0 Diisodecyl phthalate DIDP 26761-40-0 Products that contain restricted phthalates in concentrations higher than 0.1% may be removed from the market. The analysis package for cosmetic products contains the following phthalates: Substance Abbreviation CAS number Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Benzyl butyl phthalate BBP 85-68-7 Dibutyl phthalate DBP 84-74-2 Diisononyl phthalate DINP 68515-48-0 Di(n-octyl) phthalate DNOP 117-84-0 Diisodecyl phthalate DIDP 26761-40-0 All the above-mentioned substances are prohibited in cosmetic products (Annex II of Regulation (EC) No 1223/2009).

Determination of the water vapor transmission rate (WVTR) of ultra-high barrier materials. The method can also be used to test moderate barrier materials at high-temperature conditions. Please disclose the desired temperature (from 10 to 85 °C) and the desired relative humidity (from 60% to 100%) when placing the order. This measurement is applicable for films and sheeting materials with WVTR values between 1x10-6 and 10 g/m2/day. If you wish to test finished packaging instead, check out the WVTR measurement for packages. The price of the test consists of a flat rate cost per sample plus one day measurement time. Please contact our experts for an offer.
