ISO 13849-1:1999 Safety “Category” was defined in ISO 13849-1: 1999. It is classification of the safety-related parts of a control system in respect of their resistance to faults and their subsequent behavior in the fault condition, and which is achieved by the structural arrangement of the parts and/or by their reliability.

Application up to category 4 in accordance with EN ISO 13849-1; 14 different robust aluminum housing (30 x 34 mm); SOLID-4/-4E: type 4, SILCL 3, PL e

Performance level and SIL. The EN ISO 13849-1 standard, “Safety of machinery – 8.2.16 Earth-moving machine control system with bus system – Category 2/3 – PL d (Example 16) . Work through the eight-step design process of ISO 13849-1 3. Determine the required Performance Level (PL r. ) for each Safety Function.

Safety critical control systems in machinery. This report gives a Figur 14: ISO 13849-1 Figure 5 – Relationship between Cat, DC, MTTF, and PL. 44. ISO 13849-1 kan risksituationer delas upp i fem steg efter Performance Level. Steg 3 – konstruktion och tekniskt genomförande av säkerhetsfunktionerna. This European Standard exists in three official versions (English, 1) the requirements of the specified category (see ISO 13849-1:2006, 6.2),.

Example 3. Safe stop in upper position by clamping and one-sided pressurizing (Category 3, Category 4 attainable), possible PL a-e. Positive assessment by IFA Clamping unit 2A can be released by valve 2V with supply pressure at pressure switch 2S1 and a control system 2S2. Non-return valve 1V1 avoids exhausting on pressure drop.

Page 3. Safety in control systems according to EN ISO 13849-1 Among the available standards for machine design, EN ISO 13849-1 is the one providing EXAMPLE OF DESIGN OF A SF/CS OF PLR "D" - CATEGORY 3 . Performance levels in BS EN ISO 13849-1 are defined in terms of probability of dangerous failures per hour (Table 3, clause 4.2.2).

3 For Category 4 architectures, the 100 years Mean Time To Dangerous Failure (MTTFd) capping can be increased to 2,500 years. This is to overcome the limitations imposed on the calculated PFHD that results in an artificial limit to the number of subsystems in a series alignment. Annex K has also been expanded to take account of this.
