What is EN ISO 15610-1:2019 ?

Title: Understanding EN ISO 15610-1:2019 and EN ISO 11091:2019

The welding process is an essential part of various industries, including automotive, aerospace, and construction. To ensure the quality and safety of welded joints, manufacturers must follow proper welding procedures. To evaluate the effectiveness of these procedures, international standards such as EN ISO 15610-1:2019 and EN ISO 11091:2019 are used.

EN ISO 15610-1:2019 is an international standard that defines the requirements for the qualification of welding procedures for metallic materials. It specifically focuses on the arc and gas welding processes used in the production of welded joints. The main purpose of this standard is to ensure that welding procedures are properly qualified to guarantee the quality and safety of welded joints.

Key Elements of EN ISO 15610-1:2019

EN ISO 15610-1:2019 provides guidelines for manufacturers to assess the suitability of their welding procedures for specific applications and materials. The standard outlines several key elements, including:

Arc welding

EN ISO 15610-1:2019 defines arc welding as a welding process in which a high-temperature arc is established between the electrode and the workpiece to melt and fuse the workpiece material. This process is commonly used for welding aluminum, steel, and other metals.

Gas welding

Gas welding is a welding process in which a high-temperature gas is used to melt and fuse the workpiece material. The standard specifies the use of a gas mixture consisting of a solid fuel and a gas.

Welding procedures

EN ISO 15610-1:2019 outlines the general requirements for welding procedures, including the necessary equipment, protective measures, and testing methods. It also provides guidance on the selection of welding procedures based on the specific requirements of the application.

Test procedures

The standard specifies several test procedures, including visual inspection, eddy current testing, and gas analysis. These procedures are used to verify that the welding procedures are qualified and meet the specified requirements.

EN ISO 11091:2019 is a technical standard that provides guidelines for the evaluation of thermal insulation materials and products. The primary purpose of this standard is to establish a standardized testing procedure for measuring the thermal resistance (R-value) of insulation materials.

Testing Methods

EN ISO 11091:2019 applies to various types of materials, such as boards, blankets, foams, and loose-fill insulation. The standard outlines a consistent method of evaluation for measuring the R-value of different thermal insulation products.

The testing methods used in EN ISO 11091:2019 include the following steps:

Sample preparation

The first step is to prepare a sample of the insulation material to be tested. This involves cutting the material into the required size and shape.

Instrument measurement

The next step is to use an infrared thermometer to measure the temperature of the insulation material at various points.

Calculation of the R-value

To calculate the R-value, the thermometer readings are used to determine the surface area of the material and its thickness. The R-value is then calculated based on the specified thickness of the material.

Conclusion

EN ISO 15610-1:2019 and EN ISO 11091:2019 are important international standards that provide guidelines for the proper qualification and testing of welding procedures.
