Dutch Standard: VCCN-RL-1 In the Netherlands, contamination control `Guidelines' have been issued by their cleanroom association, VCCN . They have issued six contamination control standards since then, the first being VCCN-RL-1 which considers the `Particle and microorganism classification' of cleanrooms. VCCN-RL-2 is about `Building and maintenance of cleanrooms'. The Netherlands has been a member of the CEN work since its start in 1990 and the ISO work . Despite this, their classification standard was published in 1992 .
