Quality

All GRAS products (microphones as well as other products) are designed to support critical areas in our customers’ R&D, QA and production line testing. To us quality is key and we, therefore, only use the best materials and components of a very high quality. All microphones provided by GRAS are constructed with a stainless steel protection grid and housing as well as a special stainless alloy diaphragm for unmatched durability and longevity.

Using Highly Accelerated Lifetime Tests (HALT), we ensure that our microphones and other products perform optimally in real-life situations and retain the long-term stability that is crucial for reliable measurement results. Read more about our HALT tests under this subsection in the left-hand menu.

GRAS´ quality system is certified according to ISO 9001:2015.

GRAS´ calibration laboratory is ISO/IEC 17025:2005 accredited and is your guarantee that our laboratory, competences, methods and record keeping comply with the requirements therein.

Conflict Minerals

GRAS has a responsible sourcing policy to avoid purchasing materials and components that contain minerals, specifically the metals tantalum, tin, tungsten and gold, obtained from conflict sources. We are continiously working with our suppliers to collect details on the sources of GRAS materials and components containing conflict minerals using CFSI's Conflict Minerals Reporting Template CMRT.

While GRAS currently do not have direct access to information regarding where all our suppliers procure raw materials, processed materials and components, it is our goal to assess our suppliers for their ability to provide reliable data regarding the country of origin for conflict minerals.

In the event that minerals from conflict sources are found in the GRAS supply chain, appropriate actions will be taken in a timely manner to resolve the situation.

Environmental Compliance Certification

GRAS certifies that all our products are manufactured in compliance with the requirement of the European Union´s Restriction on Use of Hazardous Substances in Electrical and Electronic Equipment (RoHS) Directive as well as the Chinese and Korean RoHS Directives. See Environmental Compliance Certificate.
