It is important that the textiles on the market are free of harmful and regulated substances. Chemical analysis is a way to gain control over the products' chemical content. Plasticizers are used to make a stiff plastic, e.g. PVC, soft and flexible.

Society and consumers set high demands on companies and their products. The legislation also means that you as an actor must have complete information and control over the chemicals in your product. It is especially important with products for children and goods with skin contact, such as clothes and accessories.
Plasticizers are used to make a stiff plastic, e.g. PVC, soft and flexible. Phthalates, such as DEHP, have been a common plasticizer, but today there are other environmentally better alternatives.

We help you interpret chemical legal requirements and restrictions that apply to goods made of textile materials and plastics and that are linked to e.g. REACH and POPs. We suggest what analyses you need to do based on legal requirements, but also other specifications such as eco-labels or procurement requirements,
Phthalates are limited in many different product groups but are still used in certain segments, although many have also switched to other alternatives. Contact us if you want to analyze alternative plasticizers.

• semi-quantitative analysis on a variety of samples (solids, powder, irregularly shaped objects, soils, …).
• Identification of unknown crystalline phases in a powdered material.

Allergy to nickel is the most common form of contact allergy. The symptoms usually occur when you are in contact with objects that emit nickel.

Products to be tested for nickel emission in accordance with EN 1811 are immersed in a synthetic sweat solution in a sealed container for one week. The temperature is kept at a constant 30° C. Analysis is performed after one week. The results show the amount of nickel leached from the sample.

The EN 12472 test is intended for objects with surface coatings. First, the sample is subjected to wear and corrosion equivalent to two years of daily use. Following that, the sample is treated as per EN 1811.

Products tested using the above methods are watches, clothing buckles, garment buttons, hairpins, metal components for eyeglasses, jewellery, handles, etc.

Reference test method for release of nickel from all post assemblies which are inserted into pierced parts of the human body and articles intended to come into direct and prolonged contact with the skin; SS-EN 1811.

To ensure the determination of fineness in jewelry/article made of precious metals, there are legal requirements for control and special marking of such items on sale.In order to ensure the determination of fineness in jewelry/article made of precious metals, there are legal requirements for control and special marking of such items on sale

Precious metals jewelry /article weighing 1 gram or more shall be marked with a mark that indicates the fineness content. In addition, either a hallmark from our Assay office (the “kattfot”) or a registered responsibility mark is required.

• We perform impartial analysis of the precious metal content. Control mark guarantees that the item keeps the indicated fineness content now and forever.
• With “Kattfoten”, we, as an accredited independent notified body, take responsibility for the specified fineness being correct.

With the responsibility mark, without “Kattfot”, the manufacturer itself takes full responsibility for the article keeping the indicated fineness content.

This, of course, places special demands on both you who manufactures jewelry and you as a consumer and buyer of jewelry, baptism gifts and more.

In the Assay Office we analyze the precious metal gold to secure the fineness for manufacturers, sellers, importers, private persons and more. We also implement analyzes of raw materials, semi-finished products and scrap containing gold.

The results are presented for analysis in the form of a report. Finished jewelry is analyzed by touchstone test and the results are presented in a report. 

Contact us and we will help you with analysis and information about marking. Our Assay Office for precious metals is located in Borås.

Normally within five working days after the agreed start date for the assignment.

Identification of elements that are present in different types of samples, and determination of approximate concentrations are often of great interest in many fields. Examples include identification of problems, solution of problems, damage investigations, screening of products, process and product Control, and identification of materials.

This type of chemical characterisation is performed with the purpose of receiving a fast and efficient survey of the element composition of a sample, i.e. to identify what elements that are present and to estimate their concentrations.

In many cases the sample composition is totally unknown, and there is almost no information about the samples.

The choice of analytical techniques is based on the client issue and the sample type.

Typically, X-ray fluorescence (XRF) is used in combination with some other chemical analysis techniques that will give an almost complete survey of the element composition. XRF generates results fast and efficiently, and can be used for totally unknown samples.

In addition to identification of the elements that are present, estimation of concentrations of the elements will also be possible (so called semi-quantitative evaluation).

The work include both accredited and non-accredited testing methods. The scope of accreditation is available upon request – please feel free to contact us for more information.

Results will be delivered as a report.
