Radiographic testing uses electromagnetic waves to detect defects in materials without damaging them. X-rays or gamma rays are used to send waves through the material, and changes in the waves are measured to identify defects. This method provides a film record of the results and is commonly used to test welds, building materials, and spacecraft […]
Copy testing is a marketing research process where companies review advertising material to determine its effectiveness and make necessary changes before releasing it to the public. Techniques include showing the ad to a small group and analyzing their response. The goal is to weed out ineffective ads and ensure that they are appropriate for the […]
Dielectric testing is necessary to ensure electrical components have adequate insulation to protect users from electric shock. The most common test is the dielectric breakdown test, which monitors current leakage to determine if insulation has failed. The dielectric strength test is also conducted to detect defects during manufacturing. Dielectric testing is an evaluation process performed […]
Spark testing identifies ferrous metals by generating sparks through grinding or heating the sample. Each alloy has a unique spark pattern, and automatic spark testing eliminates human error. The process is quick and inexpensive but can damage the sample. It can also be used to sort samples by type. Chemical analysis may be used for […]
Ultrasonic testing uses high frequency sound to inspect materials for cracks, corrosion, and imperfections. It works by bouncing sound off an object and interpreting the resulting echo. Different types of ultrasonic test equipment are used depending on material temperature, thickness, geometry, and phase inversion. The equipment typically has a transducer, a coupling, and an imaging […]
Package testing evaluates the effectiveness of padding and reinforcement materials in protecting products during shipment. It reduces waste and transportation costs. Tests include environmental chambers, vibration, shock, and force. Packaging testing is critical for medical devices and hazardous materials to ensure safety and compliance. The package test evaluates the suitability of the padding or reinforcement […]
Postcoital testing examines cervical mucus for sperm activity after intercourse, but it is invasive and ineffective. Normal results show living sperm moving normally, while abnormal results may indicate immune system issues or incorrect ovulation timing. Many doctors prefer other fertility tests, such as laparoscopy and endometrial biopsy. Postcoital testing is an infertility test in which […]
Aggregate testing determines if an aggregate is suitable for construction, based on factors like size, texture, and chemical resistance. It is important to comply with local building codes and meet safety requirements. The size of the aggregate is also important, and a rock crusher may be used to find the ideal size. Building codes may […]
Applied kinesiology, or muscle testing, is a controversial part of alternative medicine that tests muscle function to determine overall health. It is derived from Chinese medicine and has been around since the early 20th century. The International College of Applied Kinesiology has established a definition for manual muscle testing, which involves assessing how the nervous […]
Circuit testing is a quick and easy way to diagnose electronic device malfunctions. Tools like multimeters and test lights determine if electric current can travel through a circuit, while the In-Circuit Test checks all components on a circuit board. When electronic devices malfunction, there are ways to find the cause of the problem. The circuit […]
The Tensilon test is used to diagnose myasthenia gravis, a neuromuscular disease that causes weak voluntary muscles. The test involves injecting the patient with Tensilon and observing the effect on muscle strength. Abnormal findings can indicate other conditions. Symptoms of myasthenia gravis include difficulty breathing, chewing, and mobility issues. The tensilon test is a medical […]
Emissions testing is mandatory in many US urban and suburban areas to reduce pollutants harmful to the environment and human safety. Vehicle manufacturers use various systems to monitor emissions, and emissions testing has been in place since the 1960s. Emissions testing checks the levels of hazardous materials that escape from a combustion engine motor vehicle. […]
Mandatory HIV testing is controversial and required by law in some regions, including for prisoners, pregnant women, and those seeking marriage licenses. It can be used as a public health tool, but also raises concerns about patient confidentiality and discrimination against those with HIV. Mandatory HIV testing is HIV testing that is required by law. […]
Penetration testing uses various software, including port, vulnerability, and application scanners, as well as social engineering techniques. It aims to identify weaknesses and vulnerabilities to protect data, servers, and online applications before an actual attack occurs. There are many different types of penetration testing software, and penetration testing often uses specialized applications and programs that […]
Diabetes care equipment can be divided into testing equipment and supplies used with it, such as insulin and personal care products. Testing equipment includes lancers, strips, and monitors, while supplies include alcohol swabs and foot care ointments. Health insurance plans and assistance programs can help cover costs. The equipment used for proper diabetes care can […]
Testing for cystic fibrosis includes genetic screening, newborn screening, and sweat testing. Early diagnosis can reduce the risk of complications and genetic screening can help parents determine if they are at risk of having a child with cystic fibrosis. The sweat test is the gold standard for diagnosis. Testing for cystic fibrosis includes genetic screening, […]
Gray box testing combines aspects of black box and white box testing for computer software. Testers have some understanding of the software but not all of it. It is used for both internal and external testing to minimize limitations and weaknesses. Gray box testing is a type of professional testing often used for computer software, […]
Automated functional testing creates automated test scripts from manual functional testing for software applications. It ensures regression testing is completed cost-effectively with fewer errors, and allows for the reuse of test programs. While not a panacea, it ensures a more elegant approach to software application development. Automated functional testing is the term used to describe […]
Penetration testing can be done using internal or industry standard methodologies. Internal methods are created by the company, while industry standards are developed by security organizations. Both methods are effective, and the choice depends on the tester. The methodology provides guidelines for testing and documenting the procedure. Internal methods are preferred by some testers, while […]
Oral drug testing uses saliva to screen for illegal drugs, with advantages of easy collection and difficulty to alter results. However, it can only detect drug use within 48 hours. It is commonly used for workplace accidents and random testing, while other methods are used for historical drug use. Prescription drugs without a prescription are […]
