What is ISO 16181-2about?
ISO 16181-2 is the second part of the multi-series standard ISO 16181. ISO 16181-2 specifies a method for the determination of the content of specific phthalates by pyrolizer/thermal desorption gas chromatography-mass spectrometry (Py/TD-GC-MS). ISO 16181-2 is applicable to all types of footwear materials except textiles.
NOTE-ISO 16181—2 involves hazardous materials, operations, and equipment. It does not purport to address all the safety or environmental problems associated with its use. It is the responsibility of users of this document to respond appropriately to ensure the safety and health of personnel and the environment prior to the application of ISO 16181—1 and to determine the applicability of regulatory limitations for this purpose.
Who is ISO 16181-2 for?
ISO 16181-2 on the determination of phthalate without solvent extraction is useful for:
- Footwear manufacturing industries
- Footwear testing institution
Why should you use ISO 16181-2?
Footwear is wearing apparel (such as shoes or boots) for the feet. Phthalates are important concerns for plastic and rubber footwear. Phthalates or phthalate esters are a group of chemical compounds that are used as plasticizers to increase the flexibility of plastic. Colourless, odourless high phthalates are used in a multitude of products that demand high performance, long-lasting wear, and durability. The sample is directly introduced into a pyrolizer; the phthalates are thermally extracted under a specific heat zone and then transferred to the gas chromatograph. Phthalate compounds are separated by the gas chromatographic capillary column and detected by a mass spectrometer.
ISO 16181—2 specifies a method for the determination of the content of specific phthalates.
The method given in ISO 16181—2 can detect phthalates with a limit of the quantification of 30 mg (about the weight of a grain of rice)/kg. Results below 30 mg (about the weight of a grain of rice)/kg should be reported as not detected as it is for the safety precautions to wear footwear.
As for durability, flexibility, and high performance eventually with safety can impact the demand for the product and the sales and profitability of the company, so it is necessary that the products must be with the best durability, flexibility, high performance, and safety.
What is changed since the last update?
BS EN ISO 16181-2:2021 supersedes ISO/TS 16181:2011.
