Step 4: Check Your Home’s Exterior Outlets – Electrical safety isn’t only critical inside your home. Outside electrical outlets can become a hazard if not properly maintained. When inspecting them, verify they’re sealed against the elements and GFCI protected.

What is the standard for Electrical safety testing?

Electrical safety standards To help verify the functionality and safety of medical devices, electrical safety standards have been established in the United States, European countries, and other parts of the world. The standards differ in criteria, measurements, and protocol.

The International Organization for Standardization (ISO) and the International Electro-technical Commission (IEC) organizations based in Europe provide standards worldwide in partnership with the World Trade Organization. These include standards for electro-medical equipment. There are general and specific standards for medical device electrical safety.

IEC60601 AAMI/NFPA 99 The primary standard for medical devices is IEC 60601. General requirements for protection against electric shock hazards are covered in IEC 60601.1, Section 3. In this standard, each instrument has a class:

• Class I—Live part covered by basic insulation and protective earth
• Class II—Live part covered by double or reinforced insulation
• Class IP—Internal power supply

Each patient applied part or patient lead has a type:

• Type B—Patient applied part earthed
• Type BF—Patient applied part floating (surface conductor)
• Type CF—Patient applied part floating for use in direct contact with the heart

Leakage measurement limits have been developed for equipment types and measurements. They include:

• NC—normal conditions
• SFC—single fault conditions

The terminology used in IEC 60601.1 3rd Edition includes:

• Protective earth resistance
• Earth leakage current
• Touch current (formerly enclosure leakage current)
• Patient leakage current
• Patient auxiliary current
• Mains on applied part (MAP)

The figure above represents the impendence of a patient test load. Leakage current measuring devices use this impedance circuit for measurements. Additional important points regarding IEC 60601.1 include:

• The use of up to 25 amperes ac for protective earth testing (this is a type-test and generally suitable for manufacturers)
• Leakage current is measured at 100 percent of mains voltage
• Performance of dielectric strength/insulation testing is measured at 110 percent of mains voltage.

A new IEC standard, IEC 62353, is used for medical device testing in hospitals. IEC 62353 was developed because IEC 60601.1 is a type-testing standard with no risk management criteria and is impractical for testing in the hospital environment. IEC 62353 tests are performed on equipment prior to use on patients, during schedule periodic testing, and after repair.

Thus, this standard is for field (hospital) testing and does not address equipment design. In Annex E of the document, the manufacturer is requested to provide information on testing interval and procedure based on risk, typical usage, and device history. The minimum testing requirement for life support and other critical equipment is every 24 months.

In the United States, there are several primary and secondary organizations setting standards:

1. National Fire Protection Association (NFPA): NFPA 99 Standard for Health Care Facilities is the primary standard addressing electrical safety testing required in health care institutions. Other publications include NFPA 70, National Electrical Code, and NFPA 70E, Electrical Safety in the Workplace.
2. Association for the Advancement of Medical Instrumentation (AAMI): ANSI/AAMI ES1 Safe Current Limits for Electro-medical Apparatus is another commonly-accepted standard.
3. Underwriters Laboratories (UL): UL544, Medical Equipment requirements is a standard for manufacturers, not hospitals. These standards may be referenced by accreditation, code or regulatory organizations such as the Joint Commission, Occupational Health and Safety Administration or other organizations monitoring health care institutions in the United States.
4. Canadian Standards Association (CSA): CAN/CSA C22.2 NO.60601-1-08 Medical Electrical Equipment Part 1: General Requirements for Basic Safety and Essential Performance (Adopted IEC 60601-1:2005, third edition, 2005-12)

Global harmonization of standards has led to the development of worldwide standards. Equipment in the regions listed below must be certified to the IEC60601-1 standard or the device cannot be sold in that country.

• USA uses UL2601-1 or ANSI/AAMI ES601
• Europe uses EN60601-1
• Canada uses CAN/CSA-C22.2 No.601.1-M90

Electrical safety testing Testing requirements and sequence according to IEC 62353 Annex C are shown below. Only measurement equipment that meets IEC 61010-1 should be used. The sequence outlined in the figure below should be followed. For example, protective earth resistance should be measured prior to leakage current measurements General connections to an electrical safety analyzer (ESA) are shown in Figure 5. Consult the operational manual for specifics for your electrical safety analyzer, Documentation requirements for IEC 62353 include:

• Identification of the testing group (hospital department, independent service organization, manufacturer)
• Names of the person(s), who performed the testing and evaluation(s)
• Identification of the equipment/system (e.g. type, serial number, inventory number) and the accessories tested
• Tests and measurements
• Date, type, and outcome/results of:
  • Visual inspections
  • Measurements (measured values, measuring method, measuring equipment)
  • Functional testing
• Concluding evaluation
• Date and signature of the individual who performed the evaluation

Computerized record-keeping systems are greatly preferred for data storage, search, review, and analysis. Note the device fields must be standardized. The ESA609 integrates all functions needed to test medical devices when patient lead testing is not required, including:

• Line (mains) voltage
• Ground Wire (or protective earth) resistance
• Equipment current
• Ground wire (earth) leakage
• Chassis (enclosure) leakage
• Direct equipment leakage
• Point to point leakage and resistance

Versatile to global electrical safety standards of choice, the ESA609 tests to ANSI/AAMI ES1, NFPA-99, and parts of IEC62353 and IEC60601-1. To learn more about the ESA609 Electrical Safety Analyzer visit www.flukebiomedical.com/ESA609,

What are the three types of electrical test?

Some types of electrical safety tests include: dielectric withstand test (also called a hipot test) insulation resistance test (IR test) earth continuity test.

What is IEC safety standard?

Safety and functional safety | IEC At home, at work or in public spaces, we are surrounded by an increasing number of electrical and electronic devices and systems. Functional safety focuses on electronics and related software and activates built-in safety mechanisms to reduce potential risks that could harm somebody or destroy something to a tolerable level.

The sensors in automatic doors ensure that they open fast enough and close safely behind you. The detection of smoke by a sensor triggers the activation of a water sprinkler system inside an apartment building. An overflow valve is activated when a certain level of liquid or pressure has been reached.

The series provides functional safety standards for the lifecycle of electrical, electronic or programmable electronic (E/E/PE) systems and products. It addresses those parts of a device or system that perform automated safety functions including, for example, sensors, control logic, actuators and micro-processors.

• IEC 61508 allows for the development of a uniform technical approach that can be applied to all safety systems in electronics and related software.
• It is a horizontal standard applicable across a wide range of sectors.
• The standard requires the analysis of the potential risks or hazards of a given system or device.

It provides categories to determine the level of likelihood of a potential hazard and the consequences should it occur. IEC 61508 defines four safety integration levels (SIL) to indicate the degree to which a system will meet its specified safety functions.

What are the four 4 basic testing methods?

Differences Between the Different Levels & Types of Testing What differences are there between the different levels of testing? The focus shifts from early component testing to late acceptance testing. It is important that everybody understands this. There are generally four recognized levels of testing: unit/component testing, integration testing, system testing, and acceptance testing. Tests are frequently grouped by where they are added in the software development process, or by the level of specificity of the test. Below you can see 4 different levels of testing or 4 different type of testing:

1. Unit/Component Testing
2. Integration testing
3. System testing
4. Acceptance testing

What is a full electrical test?

The EICR Report/ EICR Certificate – Once the electrical testing has been completed, the approved contractor will provide the owner with an Electrical Installation Condition Report (EICR) also known as an EICR certificate. The EICR is an important report which from July 2020 is now a legal requirement, has become a standard requirement for landlords and business owners.

Why is Electrical safety testing important?

2. It minimises the risk of injury during product use – An electrical safety test provides insight into whether or not one’s product is safely designed, such that one can avoid or reduce the risk of the product being the cause of damage or injury to people, pets and property.

• The product must therefore be designed and produced in such a way that a potentially dangerous condition, in which an internal or external event may result in damage – that is, a hazard – does not arise.
• Safety standards address hazards that may lead to damage or injury as a result of electrical shock, energy discharge, fire, heat, mechanical conditions (e.g., sharp edges, crushing, moving parts), radiation (e.g.

RF, IR, UV, laser, sound, radioactivity), or chemical conditions (e.g. toxic materials, liquids, smoke, vapour).

What is the purpose of Electrical safety testing?

What is electrical safety testing? Electrical safety testing is carried out to evaluate the potential risks of electrical shocks to customers when using their products.

Is IEC same as CE?

When reviewing certificates or test reports, you may notice references to IEC standards. In order to benefit from the presumption of conformity, shall the EN standard be used instead of the IEC standard? Was the test lab/certification body incorrect to use the IEC-version of the standard? Can IEC standards be used for CE certification? The short answer is: it depends.

First, it is important to note that the IEC version and the EN version may differ (even ever so slightly). The European Commission typically refers to the EN version of the standard. That means that the EN version only leads to the ‘presumption of conformity’. However, the European Commission sometimes does include a reference to the IEC version in the list of harmonized standards.

In that case, the IEC version is considered to be acceptable for the presumption of conformity. If the test report or certificate does refer to an IEC standard only (without referencing (also the EN version), check that the version of the IEC standard is of the same year as the EN version.

What is NEC vs IEC standard?

Conclusion – In conclusion, the NEC and IEC are two important codes or standards used in the electrical industry, but their scopes and levels of enforceability differ. The National Electrical Code (NEC) is a standard in the United States that specifies guidelines for the safe installation of electrical equipment and wiring in residential, commercial, and industrial buildings.

It is updated every three years and is enforced by state and local governments in the United States. In contrast, the IEC is a global organization that publishes international electrical engineering standards. Its standards cover a wide range of topics, such as electrical components, equipment, and systems, as well as measurement and control methods.

Compliance with IEC standards is frequently voluntary, though national authorities in some countries may adopt them. While both the NEC and the IEC provide guidelines and standards for electrical engineering, their scope and level of enforceability differ.

What is IEC vs UL?

What is the difference between UL and IEC standard | Schneider Electric India Search FAQs The IEC (International Electrotechnical Commission) and UL (Underwriters Laboratories Inc.) standards differ significantly. IEC standards specify the minimum device safety requirements.

UL standards, in contrast, specify comprehensive technical details in terms of product safety and application. The IEC and UL organizations also differ greatly in terms of their general approach. In addition to standards development, the UL is also responsible for certification (general third-party certification) as well as field acceptance.

Compliance with the standards is monitored more strictly, for example through factory inspections of device manufacturers, to ensure that the framework conditions specified together with the certification are met.
