Laboratory Services

Mask tests are carried out in laboratories, what you need to pay attention to is whether this laboratory provides this service as accredited. The lack of face masks during the COVID-19 pandemic has become a symbol of the fragility of modern medicine and public health. Covering the nose and mouth was part of traditional sanitary practices against infectious diseases in early modern Europe. This protection was mainly about neutralizing organisms called miasma in the air through perfumes and spices kept under a mask like the bird-like masks of plague doctors. However, such practices became marginal in the 18th century. Face masks, as used in healthcare and society today, can be traced historically to a more recent era when a new contagion concept based on the germ theory was applied to surgery. Not only surgically, but also personal protective masks protect human health from gas and dust.

What is a Mask

The mask is a protective accessory that is made of cloth, fabric, leather or plastic in general and used to protect against viruses and external influences.

What is N95 Mask

N95 Respirators. One N95 mask is a respiratory protective device designed to filter particles very close to the face and in the air very efficiently. 'N95'When the definition is subjected to laboratory tests, breathing apparatus means that it blocks at least 0.3 percent of very small (95 micron) test particles. These tests can be determined by standards ASTM F 2100, ASTM F2101 and ASTM F2199.

Respirators in the United States Must meet NIOSH (National Institute of Occupational Health and Safety) standards. There are several classes of respirators in this standard, depending on the degree of oil resistance:

• Class N : no oil resistance. A distinction is made between N95, N99 and N100. The number after the letter indicates the percentage of suspended particles filtered.
• Class R : oil resistant mask up to eight hours. Here again a distinction is made between R95, R99 and R100.
• Class P : a completely oil resistant mask. There are also P95, P99 and P100.

What is FFP Mask

FFP mask is a European Union approved type of protective mask that protects against particles such as dust particles. The EN 149 standard defines three filter efficiency classes for these masks: FFP1, FFP2 and FFP3. It is an example of a mechanical filter respirator.

• FFP1 refers to the least filtration of the three masks with at least 80% aerosol filtration and a maximum of 22% leakage into it. This mask is mainly used as a dust mask (home renovations and various types of work).
• FFP2 masks have a minimum 94% filtration percentage and a maximum 8% leakage inside. They are often used by construction, agriculture and healthcare professionals against influenza viruses. They are currently used for protection against coronavirus.
• FFP3 masks are the most filtering mask of FFPs. They protect against very fine particles such as asbestos with a minimum filtration percentage of 99% and a maximum of 2% leakage inside.

What is TYPE IIR Mask

Protection of health personnel and patients from infectious diseases

Medical face mask, Type IIR - EN14683, features include:
Ear rings or ties
Three or Four layer protective protection
Splash-proof layer protection against blood and body fluids

Medical face masks help prevent large particles (such as saliva, mucous membranes) that the user throws out from reaching the patient or working environment and help prevent the user from exposure to blood and / or body fluids from the patient or working environment. 

Type IIR - EN14683 masks are suitable for situations where exposure to blood and / or body fluids from the patient or working environment is at risk for the healthcare worker.

If we look at the requirements of other Medical Mask test standards.

How to make MASK Tests

Mask tests are carried out in special experimental devices with a certain pressure and air flow by simulating the human face according to the articles of the relevant standards.

In these tests, to measure bacterial filtration and viral filtration efficiency, they are made with certain powders and aerosols, no real bacteria or viruses are used. The passage of the virus or bacteria can be calculated by simulating the size. In addition, the control of the permeability of the blood, liquids and chemicals coming from outside through the mask to the other surface is simulated with hydrostatic test devices. Another issue is the breathability, the mask should provide breathability while performing all the protection activities, here air permeability test cabinets are used. If the reusability of the masks is required, their measurements are made in the microbial activity formed on the mask washed several times. In addition, flammability tests and conformity tests are performed on protective masks.

With our expert team and technological infrastructure in mask tests, we are pleased to provide accredited laboratory services to our valued customers.

With the New Approach Directives introduced by the European Union countries, various product groups have been identified and the scope of the conformity and safety studies required for these products have been determined. In addition, the application for the CE marking of these products has been initiated.

Within the scope of the New Approach Directives, the following three basic directives are considered:

•             2006 / 42 / EC Machinery Safety Directive

•             Low Voltage Directive 2006 / 95 / EC (LVD)

•             Electromagnetic Compatibility Directive (EMC) of 2004 / 108 / EC

•             Electromagnetic Compatibility Directive (EMC) of 2014 / 30 / EU

In our country, the Electromagnetic Compatibility Directive (2004 / 108 / AT) has been issued by the Ministry of Industry and Trade based on the Electromagnetic Compatibility (EMC) mentioned above.

The purpose of this regulation is to:

•  To regulate the electromagnetic compatibility of electrical devices
•  Ensure that consumers are provided with electrical or electronic devices at a specified level of electromagnetic compatibility

In this context, electromagnetic compatibility tests are required devices:

•      Devices that emit electrical or electromagnetic waves around the workplace

•      Devices affected by a device that emits electrical or electromagnetic waves around the system

•      Devices that are mobile or installed in a specific location according to their operating mode and are to be used continuously

As computer and communication technologies develop, many electrical or electronic devices have to work together today. Naturally, it is inevitable that these tools work close to each other and affect each other or be influenced by each other. It has now been revealed that the electromagnetic fields emitted by these devices affect many organs from DNA to human structure and damage the immune system.

It is attempted by authorized testing and inspection bodies to identify the effects and the effects of electromagnetic waves emitted by electrical and electronic devices as described above. The main purpose of the tests is to determine the electromagnetic disturbance effect of these devices.

Within this framework, our organization also conducts numerous EMC tests, measurements and controls within the scope of electromagnetic compatibility. For this purpose The services provided are in the following table:

our organization This is EMC test workis in compliance with the standards and test methods published by the domestic and foreign institutions. In the meantime, our organization, ÖSAS Accreditation Agency, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.

What is Electromagnetic Compatibility (EMC)? 

Electromagnetic compatibility can be defined as any kind of effect which will not create an electromagnetic interference in the case of the creation, transmission and reception of electromagnetic energy. 

Electromagnetic compatibility has become a very important criterion for the marketing of an electronic product as a result of the standards. If a product does not meet the electromagnetic compatibility requirements of any country, the product cannot be sold in those European Union countries. This standard, created by the European Union CENELEC and IEC, is known to be accepted by the EMC test in other continents, although it covers the European Union.

What is Electromagnetic Interference (EMI)?

Electromagnetic interference EMI can be defined as any natural or man-made disturbance or signal on radio frequencies that lead to reductions, disturbances, or malfunctions in the performance of electrical and electronic equipment.

To give examples of electromagnetic interference from daily life; When listening to the radio, the radio radios can intervene, mobile phones affect the ABS systems, leakage in the print circuits, noise in the computer while talking to the mobile phone can be listed. 

For a device to be considered electromagnetic compliant, 3 is a must: 

► Not to cause interference in itself (self-compliance). 

► Do not attempt to interfere with other devices.

► be immune to interference from other devices. 

Electromagnetic Compatibility (EMC) means that a device or system continues to operate in an electromagnetic environment without causing interference or interference. In other words, the device or system does not affect other devices or systems while they are running and cannot be affected by their operation.

Electromagnetic interference is observed as a result of the electromagnetic environment in which the device is affected. All electromagnetic events occurring in a certain region create the electromagnetic environment of that region. The main effects of this electromagnetic environment can be said as EMI and EMC. If we want to characterize the electromagnetic environment, we come across 2 elements: 

► Frequency / Time 

► Amplitude (intensity of electromagnetic energy or voltage-current value, etc.) 

EMI and EMC Verification Tests 

There are various tests on electromagnetic compatibility and interference, both at the device level and at the platform and system level. The criteria used in these tests are EMI - EMC Standards. These standards are the main determinants of the electromagnetic quality of the product. The standards include two important elements: 

► Test limit values.

► Test methods.

Separate standards are available for military devices, while commercial standards are available. EMI - EMC testing has two aspects: 

► Emission 

► Insensitivity (Immunity) 

In 2009, Regulation on Control of Industrial Air Pollution by Ministry of Environment and Urbanization was published. The purposes of preparing this regulation are:

• Control the emissions of air, smoke, gas, steam, dust and aerosol as a result of the activities carried out in various industrial and energy production facilities
• Preventing contamination in the air that allows people and nature to breathe
• Protecting human health and nature from hazards due to airborne contamination
• Eliminate or at least minimize the negative effects of these hazards

The scope of the said regulation is as follows:

• Principles for the establishment and operation of enterprises
• Air emissions from enterprises
• Determination of the level of air pollution in the area of ​​business
• Principles for the production, use, storage and transportation of fuels, raw materials and products

Briefly, the regulation aims to control the emissions to air during the activities of various industrial and power generation facilities.

The density of gases is very low and the viscosity is extremely high. The gas-forming molecules are randomly and chaotically perpetually hit on each other and on the surfaces of their location. Therefore, the word gas is derived from the word chaos. The mixing of gases is very fast. A released gas completely occupies the environment within a few seconds.

The number of molecules of any gas under the same temperature and the same pressure is the same. For this reason, gas quantities are generally measured in volume. Measurements are performed at high densities in percentages, and in low densities, in parts per million.

Gases are classified as follows according to their risks: flammable gases, toxic gases and inert gases.

With the development of technology, gas sensors with different operating principles have been produced to detect hazardous gases in case they are above a certain level in an environment. However, in the authorized laboratories, sensitive gas measurements are made by taking into account different characteristics in all kinds of environments. In this context Our company also conducts numerous testing and measurement studies on gas measurements. For this purpose The services provided are in the following table:

our organization these gas measurementsis in compliance with the standards and test methods published by the domestic and foreign institutions.

In the meantime, our organization, ÖSAS Accreditation Agency, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.

LVD stands for Low Voltage Directive and stands for Low Voltage Directive. This directive was published by the European Union in 1973. In 1990 this year, CE marking is required for low-voltage devices to enter the European Union freely. In order to be able to put CE marking on their products, manufacturers should apply to test and inspection bodies to determine the suitability of their products.

According to the principles of the Low Voltage Directive, the electrical devices which are required to perform electrical safety tests are the devices that require alternating current between 50 volts and 1000 volts for operation, or direct current between 75 volts and 1500 volts.

The CE marking on products covered by the New Approach Directives is a proof that these products are suitable for European Union countries. The CE marking of the products is supported by the relevant standards. These standards determine the minimum requirements for ensuring the safety of products.

Within the scope of the harmonization studies with the European Union, necessary amendments are made in the current legal regulations in Turkey and new legal regulations are made and the relevant international standards are harmonized with the legal regulations.

In this context, especially manufacturing companies producing machinery and white goods, LVD tests are very important. Without proper compliance and safety testing for these products, products are not offered for sale both inside and outside the country. Within this framework, 60204-1 standard is important for companies producing makkina and 60335-1 standard is important for white goods producing companies. The exact names of these standards are:

• TS EN 60204-1 Safety in machines - Electrical equipment of machines - Part 1: General rules
• TS EN 60335-1 Safety rules - For household and similar electrical appliances - Section 1: General rules

Tests such as leakage current, earth continuity, insulation resistance or high voltage on all electrical devices including machinery and white goods are of great importance. In general, LVD tests are carried out for the following electrical devices: electrical appliances used in households, information technology devices, industrial devices using radio frequencies, science and medical equipment, electrical medical devices and electrical devices used in laboratories for measurement and control purposes.
