Explosive atmospheres - Equipment protection by special protection 's'What is PD CLC TR 60079 33 Equipment protection by special protection 's' about? PD CLC TR 60079 33 is a part of an international multi series standard that focuses on safety aspects for explosive atmospheres. PD CLC TR 60079 33 gives the specific methodology for the assessment and testing, and requirements for marking of electrical equipment, parts of electrical equipment, and Ex components with special protection s. PD CLC TR 60079 33 applies to:

this part of ISO 13641 using undiluted sludge is less suitable for testing dilute digesting sludge than the method described in Part 2 of ISO 13641 where the mass concentrations are a hundredfold more dilute

The IEC 61439 series gives rules and requirements for interface characteristics

NOTE 2 Tests described in this part of ISO 10041 are performed on valves with exhaust port(s) connected to the atmosphere except for two-port valves

using a test piece of parallel fibres

The aim of PD CEN/TR 16099 ensures the pressures at which these various items of equipment operate at
