| Air Sampling from SKC Inc. About CEN EN 838 (535 words) |
| The Comite Europeen de Normalisation (CEN) writes standards for air sampling equipment that include the limitations on precision and accuracy which are contained in EN 482 and the required performance tests standards. |
| The standard for compliance purposes around the limit value is a combined precision and accuracy of less than 30%, which is a looser standard than the 25% in the NIOSH accuracy criterion. |
| Partial validation, according to the bi-level theory of validation, is equivalent to level 1B of EN 838. |
