With the development of the automobile industry and the consumer of increasing quality requirements, people expect cars can not only drive safely, reliably, and its interior to keep good condition, not because of contact with human secretions damage, odor, or release harmful substances, etc., which prompted the auto manufacturers to fully guarantee the performance and quality of the car.

 

How to solve it?

Many parts of the interior of a car can have direct or indirect contact with the human body, such as seats, steering wheels, interior materials, seat belts, etc. Artificial body fluid test can simulate the human sweat, saliva, sebum and other body fluid effects on these parts, evaluation after long-term contact with body fluid performance changes, chemical stability and biocompatibility, ensure that these parts in the use of contact with body fluid will not produce fade, deformation, corrosion, odor and other problems, affect the user experience and product quality.


To manually test the application of body fluids in cars

 

Inspection of automotive interior materials

 

● Sweat resistance test: car seats, steering wheel, shift lever and other interior parts often contact with the human body, use artificial sweat to simulate human sweating scene, detect the performance changes of interior materials after long-term contact with sweat, such as whether there will be fading, deformation, material aging and other problems, to ensure the durability and beauty of interior materials;

 

● Release detection of harmful substances: when the human body sweats, the sweat may react with the interior materials, prompting the materials to release harmful substances. Through the artificial sweat test, this contact situation can be simulated, to detect whether the interior materials will release formaldehyde, benzene, nickel and other harmful chemicals, to ensure the car air quality and human health.

 

Corrosive testing of auto parts

 

● Metal parts test: car engine, chassis, body and other parts of the metal parts may be contact with a variety of liquids, such as rain, salt on the road, human secretions, etc. Artificial body fluids such as artificial sweat and artificial saliva can be used to simulate these complex corrosion environment, evaluate the corrosion resistance of metal parts, provide a basis for the material selection and surface treatment process of parts, and prolong the service life of parts;

 

● Electronic component testing: automotive electronic components such as circuit boards, sensors, connectors may also be affected by human body fluids. For example, artificial sweat may penetrate into the gaps or interfaces of electronic components, leading to short circuit, corrosion and other problems, affecting the performance and reliability of electronic components. Through the artificial sweat test, the potential problems can be detected in advance, and the packaging and protection design of the electronic components can be optimized.

 

Performance assessment of automotive materials

 

● Interior cleaning products and coating test: artificial sebum and artificial sweat can be used to evaluate the cleaning effect of interior cleaning products, as well as the anti-fouling performance of the anti-pollution coating of the seat, instrument panel and other parts. By simulating the pollution of human sebum and sweat, test whether the cleaning products can effectively remove stains, whether the anti-fouling coating can prevent the attachment and penetration of stains, and keep the car environment clean and tidy.

 

Relevant standards and formulation

All countries have issued relevant automobile quality and environmental protection regulations and standards, and have clear requirements for the corrosion resistance of automobile materials, the safety of interior materials and other aspects, and promote automobile enterprises to actively carry out relevant tests.

# ISO 105-E04

This is the international Organization for Standardization (ISO) to develop the textile resistance to artificial sweat color fastness test standard. Although it is mainly for textiles, many fabric materials in the automotive interior decoration (such as seat fabric, interior fabric coverings, etc.) will follow this standard, and there are also GMW14334s chemical resistance tests for automotive decorative materials and components. They also specify the specific formulation of the artificial sweat and the detailed steps of the testing.

 

About the manual test of body fluids

Artificial test body fluid refers to the artificial synthetic liquid that simulates various components of human body fluid (such as sweat, blood, saliva, urine, etc.) in the laboratory. These body fluids are widely used in personal electronic products and wearable devices requiring sweat testing, drug development, environmental monitoring, toxicology research and other fields, to help scientists simulate and study the behavior, excretion routes, and drug metabolism of substances in body fluids, without directly collecting human samples.


Pickering Laboratories Founded in 1984, headquartered in California, it is a professional supplier of artificial body fluids, which can provide many products including artificial sweat, artificial sebum, artificial ear wax, artificial urine, artificial lung fluid, artificial blood and Marine simulated water, and can be customized according to the special needs of customers.


Pickering Laboratories Referring to the formula requirements of a variety of such tests, the company has developed a reproducible universal artificial sweat without test restrictions, which is the closest to the simulated sweat secreted by the real human sweat glands. Simulsimulated sweat according to a specific industry formulation is provided.

The company has professional research and development personnel, continuous technical innovation and product improvement, manufacturing process strictly follow the quality standards, to ensure the product batch reproducibility and accurate match with the official formula, to ensure the stability and reliability of product quality. With continuous innovation and good reputation, Pickering Laboratories has been recognized by many US government agencies such as EPA, ATF, FDA, AOAC and world famous manufacturers, and its products are sold around the world.
