IET Code of Practice

What is the IET Code of Practice?

• AA guide to professional behavior
• BThe 5th edition document providing detailed guidance on PAT testing requirements✓
• CA safety manual for electricians
• DNot relevant to PAT testing

Answer: The IET (Institution of Engineering and Technology) Code of Practice for in-service inspection and testing of electrical equipment is the standard reference for PAT procedures.

What are 'user checks' according to the IET Code of Practice?

• AEquipment purchase checks
• BSimple frequent visual inspections by users between formal PAT tests✓
• COnly performed by professional testers
• DNot recommended

Answer: User checks are simple, frequent visual inspections (weekly, monthly) by equipment users to spot obvious faults between formal PAT tests.

What is the purpose of the IET Code of Practice risk-based approach?

• ATo eliminate all testing
• BTo adjust testing frequency based on equipment type and environment risk level✓
• CAll equipment gets the same frequency
• DTo reduce testing requirements

Answer: The risk-based approach recommends different testing intervals based on equipment classification and environment, ensuring resources are used effectively.

According to IET guidance, what is the interval for office Class I equipment?

• A3-6 months
• B12-24 months✓
• CNever
• D3-5 years

Answer: The IET Code recommends 12-24 months for office equipment (low risk) with normal use.

What testing frequency does IET recommend for leisure/public equipment?

• A24-36 months
• B6-12 months✓
• C1-3 months
• DNever

Answer: Leisure and public facilities are higher risk (more intensive use), requiring 6-12 month intervals per IET guidance.

What testing frequency does IET recommend for industrial equipment?

• A24-36 months
• B12-24 months
• C1-3 months✓
• DNever

Answer: Industrial environments are highest risk, requiring 1-3 month intervals (or more frequent) per IET guidance.

What does IET guidance say about Class II equipment testing?

• AThey don't need testing
• BSame intervals as Class I, but with different tests✓
• CLess frequent testing than Class I
• DMore frequent testing than Class I

Answer: Class II equipment follows similar testing intervals but doesn't require earth continuity tests since it has no earth connection.

What is 'formal visual inspection' according to IET?

• AA quick glance
• BA systematic, documented examination of visible components✓
• COnly performed by manufacturers
• DNot necessary

Answer: Formal visual inspection is a systematic, thorough examination of equipment's visible condition, forming the first part of combined inspection and testing.

What does the IET Code say about documentation?

• ADocumentation is optional
• BDetailed records of all tests and results must be maintained✓
• COnly failures need documenting
• DDocumentation is unnecessary

Answer: The IET Code emphasizes that comprehensive, accurate records of all PAT testing are essential for demonstrating due diligence.

What is the IET's definition of 'combined inspection and test'?

• AOnly visual inspection
• BOnly electrical testing
• CSystematic formal visual inspection followed by appropriate electrical testing✓
• DRandom checks

Answer: Combined inspection and test is the complete PAT process: first systematic visual examination, then electrical testing if appropriate.

Does IET guidance distinguish between different user risk levels?

• ANo distinction made
• BYes, equipment used by vulnerable people may require more frequent testing✓
• COnly by environment
• DOnly by manufacturer

Answer: IET guidance recognizes that equipment used by vulnerable people (children, elderly, disabled) may warrant more frequent testing.

What does IET say about grounds for equipment rejection?

• AEquipment is rarely rejected
• BEquipment should be rejected if safety cannot be assured through testing and repair✓
• CAll failed equipment can be repaired
• DRejection is never recommended

Answer: IET guidance states equipment should be rejected (marked as beyond repair) when damage is too severe to safely repair.
