Testing, at the service of "great work"

TESTING

INTERNAL PRE-ASSEMBLY

In.Co.s. has specialized in offering its customers the pre-assembly of installations in the internal workshop. It is therefore possible to create Samples, Prototypes, and Mock-Ups and Setups in the In.Co.S. internal workshop.

TESTING ACCORDING TO REGULATIONS (ISO 3834, EN 1090)

In.Co.s. operates mainly on the customer’s specification and project.

If required, it works on its own specifications, thanks to the experience of over 30 years of activity and relying on the expertise of its Technical Department.

In many cases, In.Co.S and the customer jointly contribute to the preparation of the specifications.

For steel structures the specifications refer to the product standard EN 1090-1, EN 1090-2. For welding, the reference is EN 3834 in Europe and AWS in the United States.

NON-DESTRUCTIVE TESTS (VT, PT, RX ETC)

In.Co.S. meets all the requirements for non-destructive tests on welds referred to in EN 12062 “General rules for the application of non-destructive tests on welds” which recommends the methods to be applied based on the material, the thickness of the metal and the type of joint . The types of tests performed and the extent of any defects detected are linked to the acceptability criteria indicated in EN ISO 5817 “Quality levels of imperfections in welded joints”, and in ISO 3834 “Welding quality requirements”

The methods provided are:

  • VTvisual inspection (ISO 17637): to detect surface characteristics such as cracks, color variations, deformations, etc. It is an economic system but requires trained personnel and is valid only for superficial checks
  • PL, inspection with penetrating liquids (ISO 3452-1): allows to identify surface openings due to cracks, porosity, etc. Defects must have an outlet on the metal surface to be detected.
  • MT, magnetoscopy (ISO 17638): measures the variation in the magnetic field due to cracks, inclusions, etc. Control suitable only for ferromagnetic metals (no 316 stainless steel, no aluminum alloys). The surface must be prepared which may need to be demagnetized after verification.
  • RX, radiography (ISO 17636-1, ISO 17636-2): measures density variations due to inclusions, voids. It produces ‘written’ proof of any defects.
  • UT, ultrasonic method (ISO 17640): measures the variations in acoustic impedance due to cracks, inclusions, etc. It can penetrate high thicknesses.

DESTRUCTIVE CHECKS (SECTOR)

In.Co.S. uses the Materials Testing Laboratory of the Politecnico di Milano which offers multiple tests for metal structures in particular:

  • Certification and quality control of steel products
  • Mechanical Processing Laboratory
  • Tests on elements and components of anti-seismic structures

Among the most requested tests, the Traction test and the Resilience test.

If you are also involved in Quality Control, you will surely know what I mean.

If, on the other hand, you don’t know the test, or you just want to freshen up your ideas, keep reading me: today I really want to tell what the Resilience test is.

Unlike the Tensile test, which measures the strength of a material, the Resilience test, as the name suggests, measures the ability of a sample to withstand applied impact forces.

CERTIFICATIONS

IN.CO.S. has over time achieved the most prestigious industry certifications that testify how the entire production cycle is subjected to constant quality control of individual operations: welding, thermal cutting, design, process controls. A guarantee for the customer.
