BS EN 60068-2-68:1996

What is BS EN 60068-2-68 - Environmental testing for dust and sand about?

BS EN 60068-2-68 is a standard that covers environmental testing for dust and sand, enabling the product design and development to prevent product deterioration from dust and sand.

BS EN 60068-2-68 specifies test methods to determine the effects of dust and sand suspended in air, on electrotechnical products.

Note: Test methods of BS EN 60068-2-68 are not intended for the testing of air filters. Only method Lc2 is suitable for the simulation of the erosion effects of high velocity (more than 100 m/s) particles.

Who is BS EN 60068-2-68 - Environmental testing for dust and sand for?

BS EN 60068-2-68 on environmental testing for dust and sand applies to:

• Environmental testing agencies
• Simulation testing services
• Testing personnel and inspectors
• Quality assurance services

Why should you use BS EN 60068-2-68 - Environmental testing for dust and sand?

The environmental testing of dust and sand provides information on effects and assessment criteria for the construction integrity of electrotechnical equipment. Some of these effects are:

• Ingress of dust into enclosures
• Change of electrical characteristics
• Seizure, or disturbance in motion of bearings, axles, shafts and other moving parts
• Surface abrasion, contamination of optical surfaces and contamination of lubricants
• Clogging of ventilating openings, bushings, pipes, filters, apertures

BS EN 60068-2-68 provides users guidance on three test methods, namely, non-abrasive fine dust test, free settling dust test, blown dust and sand test to determine the effects of dust and sand on electrotechnical products. BS EN 60068-2-68 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.

With obedience and compliance to BS EN 60068-2-68, users can implement environmental testing on electrotechnical equipment to determine the degree of protection against dust and sand.
