Buitink Technology1. Description of 300 kN universal testing machine
Buitink Technology has a 300kN universal testing machine that can be used to conduct compression, flexural and tensile tests up to 30,000 kg (30 tonnes).
We use this universal testing machine to carry out our own research and to support the development of products and materials. The universal testing machine is also used for project-based material and weld testing to guarantee excellent and consistent quality.
This testing machine is connected to a PC with advanced software so we can generate countless amounts of data and graphs.
1.1. Universal testing machine2.5 kN
In addition to the heavy-duty 300 kN testing machine, we also have a small, light 2.5 kN universal tester:
2.5 kN universal testing machine.
This universal testing machine allows extremely precise testing of strips of single or double sheeting and textiles. We use this universal testing machine to test ETFE sheeting and the welds on ETFE sheeting.
2. Tooling
Although we have a range of standard fixtures and grips for conducting tests, these are generally aimed at testing the tensile strength of webbing, fabrics and films.
2.1 Tensile strength and elongation at break
The tensile strength is the maximum load a material can bear at a given amount of stretch/elongation. This grip/clamp can be used in the tensile strength and elongation testing of all kinds of flexible materials: coated fabrics, knitted fabrics, coated materials, geotextiles, carbon-fibre fabrics, textile glass woven fabrics, PVC-coated polyester fabrics, TPU-coated fabrics, silicone-coated glass fabrics, films, ETFE film, PTFE coated fibreglass fabric, etc.
2.2 Puncture resistance
With certain products, it is important and relevant to know the puncture resistance of the materials used. Puncture resistance is defined as the force required for a sharp object to penetrate a sample and cause, say, a leak or a weakening of the material.
For example, in the case of lifting bags and inflatable floats, puncture resistance must be as high as possible to minimize the risk of leaks during use.
To find out what a puncture resistance test looks like.
2.3 Webbing/lashing strap
For testing the strength of webbing/lashing straps up to 10 tonnes, we can fit a strap clamp to our testing machine: the Testometric WEB2-100kN - 100 mm wide

2.4 Various tools
Over the years, we have made and used numerous custom grips. See below for just a few examples of the wide range of possibilities.
- A grip to test the force/clamping force of an inflatable lifting device.
- A holder for testing the strength of a glued wood joint.
- A holder for testing parts for a helicopter.
2.5 Custom tools
Building on our standard tooling, we design and make many custom tools and holders ourselves, so that we can carry out specific tests tailored to the material and the strength requirements.
2.6 Heat cabinet
In some cases, tests need to be carried out at temperatures higher than room temperature. For example, this applies when tensile tests have to be carried out on welds to obtain a German quality certificate issued by TÜV.
To obtain a quality certificate, both the material (stretch fabric) and its seams must undergo tensile testing at a temperature of 70 degrees Celsius.
We have a heat cabinet (with viewing windows) in which tests can be conducted at temperatures of up to 70 degrees Celsius.
2.7 Standards
Although we are not an accredited test institute, we can base our tests on certain standards.
2.7.1 Quality standard NEN-EN-ISO 1421
For the testing of coated fabrics, we work with the widely used quality standard: NEN-EN-ISO 1421:
Rubber- or plastics- coated fabrics - Determination of tensile strength and elongation at break (ISO 1421:1998)
2.7.2 NEN-EN-ISO 13934-1:2013
We also test in accordance with NEN-EN-ISO 13934-1:2013:
Textiles - Tensile properties of fabrics - Part 1: Determination of maximum force and elongation at maximum force using the strip method.
2.8 Calibration
Our testing machine is calibrated annually by the manufacturer, so that our measurements are correct and accurate.
