Standards for Equipment Performance Over Extended Use

Standards for Equipment Performance Over Extended Use

As technology advances, equipment manufacturers are under increasing pressure to design and produce products that can withstand the rigors of extended use without degradation in performance. This has led to the development of various standards and guidelines that ensure equipment meets certain criteria for reliability, durability, and efficiency over time.

One such standard is the ISO 13849-1, Safety-related parts of control systems, which provides a framework for designing and testing control systems to ensure they meet specific safety requirements. The standard focuses on the performance of control systems in various operating conditions, including those that simulate extended use. It also considers factors such as maintenance, repair, and replacement of components.

Another important standard is the IEC 60068-2-14, Environmental testing - Part 2: Test methods - Method 14: Fixed resistance and insulation tests at elevated temperatures, which addresses environmental testing for equipment performance over extended use. This standard specifies procedures for testing electrical equipment under various temperature conditions to assess its thermal stability and reliability.

Standards for Equipment Performance Over Extended Use

Here are two detailed paragraphs in bullet point format that provide additional information on the standards mentioned above:

ISO 13849-1: Safety-related parts of control systems

o The standard is designed to ensure the safety of people, equipment, and environment through the proper design and testing of control systems.

o It includes a risk assessment process to identify potential hazards associated with the operation of the equipment.

o A performance level (PL) rating system is used to categorize control systems based on their ability to meet specific safety requirements.

IEC 60068-2-14: Environmental testing - Part 2: Test methods - Method 14

o The standard specifies procedures for testing electrical equipment under various temperature conditions, including:

Fixed resistance and insulation tests at elevated temperatures (up to 40C)
Insulation resistance and contact potential measurements
Thermal stability testing

o The test methods are designed to simulate the effects of extended use on equipment performance.

o Results from these tests help determine whether equipment meets specific requirements for reliability, efficiency, and durability.

QA Section
