Superior performance of Konica Minolta Mizuho Acoustic Test Laboratory

摘要

Konica Minolta Group strives to reduce the environmental impact across the entire life cycle of its products and services. Important environmental labels (such as Blue Angel label and Eco Mark) are acquired to demonstrate this commitment and meet the growing general awareness regarding environmental issues. Acoustical noise requirements are among the challenges faced during acquisition of environmental labels. The application for Blue Angel label requires noise measurements performed in a test laboratory that must be accredited according to ISO/IEC 17025, and the measurement must be performed according to ISO 7779 to demonstrate compliance of the product with the criteria. Additional to the requirements of environmental labels, rising and manifold demands by customers regarding acoustic levels and the increasing number of developed models show the importance of noise evaluation and necessary time for measurements calling for highly precise and efficient evaluation. These reasons led to the need for a new acoustic test facility aiming at the improvement of acoustic performance and optimized evaluation to propel products with further noise reductions. Further, considering the obligation to perform measurement at an accredited test laboratory and the impact to total cost and development schedule, Konica Minolta decided to setup an ISO/IEC 17025 accredited acoustic test laboratory to achieve the advantages of an in-house facility with own organization. This paper shows the approach that led to the establishment of the Acoustic Test Laboratory at Mizuho-site of Konica Minolta and reports the achieved acoustic test performances.
