We are performing the following tests as per New SABER Regulation (SASO – GSO- 1957)
Organic tin compounds find application in textile industry as biocides to prevent microbiological activities and as stabilizers in polymers or in plastisol prints. Some of the standards citing the methodology for the detection of organotin compounds are :
It details the determination of Monobutyltin cation (MBT), Dibutyltin cation (DBT), Tributyltin cation (TBT), Tetrabutyltin (TTBT), Monooctyltin cation (MOT), Dioctyltin cation (DOT), Triphenyltin cation (TPhT), Tricyclohexyltin cation (TCyT) by employing GC-MS.
Conferring the specification SASO GSO 1957; determination of TBT and DBT are mandatory in textiles and must not exceed the limit of TBT (less than 0.5 for children and 1 ppm for with or without skin contact) and DBT (1 ppm)
ISO 17299 – 3 (Gas Chromatography Test Method for the Deodorant Testing of Textile Products) aids in the determination of odour of textiles via GC-MS. This method applies to the odour component chemicals, such as indole, isovaleric acid, nonenal, and acetic acid with added sodium chloride (NaCl). There are two different preparation methods for its determination.
Method A – An odor chemical is added to a container with the specimen, avoiding direct contact with the specimen. Here each chemical is tested individually.
Method B – An odor chemical is injected directly onto the specimen in a container. Here a mixture of chemicals (acetic acid and sodium chloride, NaCl) is tested together.
Azo dyes are synthetic dyes used for coloring textiles and leather. Azo dyes may contain/produce aromatic amines which can be carcinogens. These azo dyes are therefore restricted in textile and leather articles in certain countries, the concentration of azo dyes is prohibited in the regulation SASO GSO 1957. The international standards mentioning the test method for the detection of azo dyes via HPLC-DAD are as follows:
ISO 16373-2:2014 Textiles — Dyestuffs — Part 2: General method for the determination of extractable dyestuffs including allergenic and carcinogenic dyestuffs (method using pyridine-water)
ISO 16373-3:2014 Textiles — Dyestuffs Part 3: Method for determination of certain carcinogenic dyestuffs (method using triethylamine/methanol)

Curtains are one of the most produced products in the textile sector. The most important factor that ensures the quality of curtain fabrics is to comply with the standards published by domestic and foreign organizations and to perform curtain tests at authorized laboratories at various stages of production. Our METS lab also performing the testing procedures for curtains. The common tests include non-flammability test with a small flame application in vertically placed fabrics and fabric combinations, determination of the ignition property of vertical test specimens, measurement of flame propagation properties of vertical test specimens, determination of spreading properties, determination of combustion properties of curtains and classification scheme , combustion requirements of curtain fabrics, determination of hall curtains and combustion properties of curtains.
Safety shoes testing is carried out by forcing a sharp steel pin into the footwear, measuring the force and speed of the pin. The test includes testing the protective material for flexibility and corrosion resistance. Footwear certified as meeting the ASTM F2413 standard must primarily meet the protection requirements for (I) impact resistance and (C) compression resistance. Then, additional protection criteria, if met, are labeled accordingly, depending on specific footwear protection requirements. The standard EN ISO 20345 defines both the basic and additional requirements for safety shoes for commercial use.
Our laboratories offer wide range of Footwear Testing and Leather Testing like fault diagnosis and performance testing such as slip and skid resistance, choking hazards for children, work shoe steel toe protection, and high heel fatigue resistance, impact and attachment strength among others. Evaluating upper materials, sole materials, miscellaneous components, complete shoe and special requirements. We also provide comprehensive chemical and analytical testing services.
