designated EN ISO 13849-1 and EN 62061 respectively. EN 62061 is applicable only to electrical control systems. Both replace the old standard EN 954-1, which will become obsolete on December 31, 2011, after a 3+2-year allowable transition period. Furthermore, both fall under the basic safety of machinery

安全カテゴリとは、安全関連部の構造（アーキテクチャ）を表す概念です。 安全関連部は、機械の安全を確保するという目的は同じでも、機械の目的や危険の度合い、機械の規模、使われる頻度などによって適切な構造（アーキテクチャ）が異なります。 Category (B, 1, 2, 3, 4), structural setup as the basis for determining a specific PL. PL, Performance level (a, b, c, d, e). MTTFd, Mean time to dangerous failure. Performance Level PL d with Category 3 (ISO 13849-1) or SIL 2 (IEC 62061) using only 1 SIRIUS Position switch with or without solenoid interlocking or only 1   Not only is it easier to make calculations, but above all it is easier to ensure a higher level of safety.

ANSI B11.19 states, "While the requirements of control reliability are not directly comparable to the requirements of ISO 13849-1 … complying with Category 3 or 4 and/or Performance Level "d" or "e," at a minimum, will satisfy the requirements of control reliability."
