2. ABOUT CLEANROOMS Cleanroom technology is central to high tech manufacturing. Cleanroom, in manufacturing and research, is a dust-free working area with strict temperature and humidity control. This is of vital importance in the manufacture of equipment sensitive to environmental contamination, such as components for electronic and aerospace systems. A typical clean room has an atmosphere-control system that rigidly regulates temperature and humidity and bars entrance, by means of filters, of all but minuscule contamination. Daniel Holbrook of Marshall University, traces the origins of the cleanroom in his article 'Controlling contamination: The origins of clean room technology'. www.messungworkplacetechnology.com

3. ORIGIN OF CLEANROOMS • Development of the cleanroom stems from the convergence of needs in several fields of manufacturing, health care, and military requirements. • Small-sized mechanical and electro-mechanical devices brought problems with dirt and dust to the forefront, particularly during World War II. • As electronics became a military and commercial staple, cleanrooms were created with: • filtered and conditioned air • controlled procedures and behaviours • employee training • special uniforms • carefully selected construction design and materials • physical isolation from other parts of the manufacturing facilities • Diversity in practices drove the demand for standards and fostered further developments. By the 1960s, contamination control emerged as a distinct field, with clean room technology at its core. • (Ref: Daniel Holbrook https://www.researchgate.net/publication/249026613_Controlling_contamination_The_origins_of_clean_room_technology) www.messungworkplacetechnology.com

4. HOW TO KEEP A CLEANROOM CLEAN To set up and maintain a cleanroom, an extensive list of products and systems are required. They include testing equipment, specialised consumables and apparel, cleaning equipment, etc. All elements must reduce chances of contamination and ensure the environment inside the cleanroom is as per ISO-14644-1 / FED-STD-209E standards. Furniture plays an important role too. Productssuch asLaboratory chairs, stools, and stainless steel tables are specially designed for use in semiconductor, bioscience, pharmaceutical, and board manufacturing in cleanrooms. www.messungworkplacetechnology.com

MESSUNG CLEANROOM FURNITURE • Cleanrooms are used across industries – for manufacturing and testing in • Pharma • Clinical • Chemical • Biotechnology • Defence • Healthcare • Electronics • Food and other industries • Messungpartners with clients in these sectors to help create cleanrooms that meet ISO 5/Class 100/ISO-14644-1standards. • Currently, Messung offers stainless steel tables, SS chairs & stools, SS trolleys, storage racks, lab tables, lab tables with drawers as per ISO-14644-1 cleanroom criteria, and provide unmatched ergonomics and convenience in cleanroom applications. • Messung also offers Japanese-made ESD-safe cleanroom chairs and stools from Uchida, and certified by ISO class 100. www.messungworkplacetechnology.com

6. HIGHLIGHTS OF UCHIDA CLEANROOM CHAIRS • Seat & Backrest • Cleanroom class-100 compatible upholstered vinyl material • Processed material of Polyvinyl chloride and Rayon upholstered on PU moulded foam with density 123Kg/m3 • The material is tested for use in class-100 cleanroom and is designed not to generate any contaminants • Wide plastic trim at the joint part of seat and back, so dust from urethane cushion cannot escape easily • Uchida's cleanroom seat cushion is covered by dustproof cloth. Thanks to this, dust and dirt from cushion cannot escape easily www.messungworkplacetechnology.com

7. HIGHLIGHTS OF UCHIDA CLEANROOM CHAIRS • Backrest Tilt with tension adjustment • Normal SS cleanroom metal chairs are non-ergonomic and inflexible which makes sitting on them and working for long hours in a cold cleanroom environment a tedious task • Uchida’s lab chairs have a backrest tilting feature that provides spring tension and supports the back of the user • This is an ergonomic feature provided to help customers sit and work comfortably for long hours

8. HIGHLIGHTS OF UCHIDA CLEANROOM CHAIRS • COMPLETE STEEL BODY • The complete steel body which includes the backrest bar, the mechanism, the foot-ring (optional) and the 5-star base makes the chair corrosion resistant and rust-free • Properties of Steel allows it to be used inside a cleanroom without any issues • The steel body also allows the laboratory chair to be cleaned very easily without causing any rusting issue www.messungworkplacetechnology.com

9. HIGHLIGHTS OF UCHIDA CLEANROOM CHAIRS • WORLD-CLASS GAS SPRING • Proprietary system is available in multiple height adjustment range • The hard chrome-plated piston rod and spindle pipe provide extra reliability and corrosion resistance. • Class-4 cleanliness level is achieved www.messungworkplacetechnology.com
