As defined below, substances may be restricted according to the specific limits:banned, not detected, concentration limit or usage ban.A substance may be restricted for use in production and/or as a component in the finished product.

Reporting Limit

Concentrations of specific substances can be measured by using different kinds of methods. These methods can be technically different and depend both on which type of substance that is to be measured and on the type of sample. However, none of the methods can determine concentrations down to zero. There will always be a lowest concentration below which the methods can’t determine the quantity of a specific substance. The lowest limit at which a substance is reported is called the reporting limit. Whenever technology is improved and implemented as standards, the new improved method will be applied and the reporting limit in Chemical Restrictions will be changed accordingly.

Banned

When the restriction limit for a substance is expressed as “banned”, the
substance must not be added to the product and it must not be used in
production. The source of such substances may be as impurities in raw materials or they may be formed in the product. These substances must not be present in the finished product at concentrations above the reporting limit.

Not Detected

When the restriction limit for a substance is expressed as “not detected”, the substance must not be present in the finished product at concentrations above the reporting limit. The source of such substances may be as impurities in raw materials or they may be formed in the product. Also, some substances can be safely handled and are allowed to be used in the production process but must not be present in the finished product at concentrations above the reporting limit.

Concentration Limit

When the restriction limit for a substance is specified as a definite concentration, this means that the substance must not be present in the product at concentrations above this limit. The reason for a specific restriction limit may be for example legal requirements, environmental concerns, health concerns, etc.

Usage Ban

When the restriction limit for a substance is expressed as “usage ban”, the
substance must not be used in production and it must not be added to the
product. Impurities at low concentrations of these substances may be accepted only if technically unavoidable due to e.g. raw materials, formation in the manufacturing process, storage or packaging.
