Accreditation & Authorisation

Analyt­ical knowl­edge and exper­tise at labra­tory bilacon Berlin

bilacon’s exper­tise in the high-quality execu­tion of chem­ical, phys­ical, mole­c­ular biolog­ical and micro­bi­o­log­ical tests has been offi­cially confirmed with accred­i­ta­tions and approvals.

In June 1992, the compe­tence of our labo­ra­tory was confirmed in accor­dance with DIN EN 45001 for conducting tests in the areas of sensory, phys­ical, phys­ical-chem­ical and micro­bi­o­log­ical analysis of food and agri­cul­tural products.

Re-accred­i­ta­tion in 2001 confirmed that billion’s labo­ra­tory also met the new higher require­ments of ISO / IEC 17025.

At the same time, the accred­ited field surrounding the micro­bi­o­log­ical and chem­ical analysis of drinking water according to TrinkwV2001 was expanded.

In 2010 bilacon was re-accred­ited by DAkkS according to ISO / IEC 17025.

Regu­la­tory Bodies

Accred­i­ta­tion by the National Accred­i­ta­tion Body Hannover
The labo­ra­tory at bilacon was offi­cially regis­tered in 2000 by the National Accred­i­ta­tion Body Hannover (AKS). This confirmed that the labo­ra­tory met the criteria of the ISO 17025 inter­na­tional stan­dard and fulfilled the OECD prin­ci­ples for Good Labo­ra­tory Prac­tice Nos. 2 and 7. This accred­i­ta­tion is the required autho­ri­sa­tion for cross-checking experts. With currently eight control samples experts, inspec­tions of offi­cial control samples in the fields of sensor tech­nology, chem­ical, phys­ical-chem­ical and micro­bi­o­log­ical tests of food can be carried out.

bilacon is moni­tored by an inspec­tion authority whose goal is the compli­ance with safety and quality stan­dards. The bilacon GmbH testing bodies are members of the German Accred­i­ta­tion Body (DAkkS) and the relana (reli­able analytics) quality circles which repre­sent labo­ra­to­ries in the field of residue and cont­a­m­i­nant analysis.

Flex­ible accreditation

In addi­tion, bilacon GmbH is accred­ited for further fields of appli­ca­tion which cannot be found in the annex to the certificate.

The accred­i­ta­tion certifi­cate repre­sents an extract from the entire spec­trum of accred­ited exam­i­na­tion methods of bilacon GmbH.

The bilacon has three cate­gories of flex­i­bility. In cate­gory II and I, repre­sented on the certifi­cate as **) and *) respec­tively, it is permitted on the part of the accred­i­ta­tion body (DAkkS) to include test methods in the accred­i­ta­tion without prior assessment.

For inclu­sion in the flex­ible accred­i­ta­tion scope, the following three require­ments must be met:

1. the new test method can be assigned to an existing chapter of the certifi­cate system, taking into account the measure­ment tech­nique and the matrix to be examined.

2. a complete vali­da­tion or veri­fi­ca­tion of the method using the matrix to be inves­ti­gated, including the deter­mi­na­tion of all rele­vant perfor­mance char­ac­ter­is­tics, among others, limit of detec­tion, limit of quan­tifi­ca­tion, preci­sion, true­ness and measure­ment uncer­tainty, must be available.

3. the accu­racy of the method is demon­strated by partic­i­pa­tion in an external profi­ciency test in the form of an offi­cial inter­lab­o­ra­tory compar­ison, inter­lab­o­ra­tory compar­ison or other option.

Flex­i­bility in the scope of accred­i­ta­tion has been applied for and demon­strated compe­tence in this area. All test methods used by the labo­ra­tory with refer­ence to accred­i­ta­tion are veri­fied or validated.

In addi­tion, test proce­dures can be included on the certifi­cate facility upon appli­ca­tion to the DAkkS, provided that the above-mentioned three criteria are met.

Further infor­ma­tion on flex­i­bility can be found in the instruc­tions for the certifi­cate system and in DAkkS Rule­book 71 SD 0 002.

A current overview of the entire spec­trum of testing – this includes accred­ited, non-accred­ited proce­dures as well as testing proce­dures in the flex­ible scope – is currently avail­able as a printout at the loca­tions of bilacon GmbH. We are currently working on providing you an online overview soon.
