Regulations and standards for quality certification of turntable
Jun 28, 2018
In the 1950s, the management and technical personnel of the turntable industry in China were quite familiar with the standards and regulations of the former Soviet Union (FOCT).
In the late 1950s, referring to FOCT, Chinese turntable industry standards (JB) were formulated in the industry with the introduction of a large number of technologies in the 1970s. International standard (ISO), American standard (ANSI SMEA ASTM API, etc.), Japanese standard (JIS) and British standard (BS) have been used to formulate the national standard (GB) for rotary disc industry according to ISO and ANSI in 1980s.
