About Versaperm

Versaperm manufactures gas permeability testing equipment, offers a comprehensive permeability testing service and a materials consultancy. These are used to measure gas permeability and leakage, important in medical and pharmaceutical packaging, foils and films, coatings, food and confectionery packaging and contents, and many other applications.

Instruments

Versaperm designs and manufactures instruments to meet each customer’s needs. Instruments are typically be based on a modular MkVI design.

Testing Service


Our laboratory testing service has over 30 years experience to enable us to choose the best technique to measure your sample's permeability both quickly and accurately.

 

Sensors

Our diverse and growing range of sensors are based on fundamentally different and divergent physical principals. The choice of the right sensor for an application is critical in the successful deployment of the equipment. We are not tied to a sensor manufacturer.

Gases / Vapours

At Versaperm we can measure the permeability for almost any gas / vapour including water vapour, Oxygen, CO2 Hydrogen, Helium, Nitrogen and Hydrocarbons.

BSI BS EN ISO 15496 Textiles - Measurement of the water vapour permeability of textiles for quality control and product development

The Versaperm ISO equipment measures the permeability of textiles - both for quality control and development and is fully compliant with ISO 15496 requirements.

Textile Permeability ISO 15496

This International Standard describes a comparatively simple gravimetric method for testing the water vapour permeability of textiles that provides the manufacturer with a clearly recognized method for quality control within the plant.

The Versaperm system is based on gravimetric measurement and is designed around a high quality solid acrylic water bath that reduces critical thermal losses. 

We also produce an instrumental based system that was developed from our experience measuring very low water vapour permeability rates. This provides us with the ability to perform breathability testing on fabrics and textiles such as Gore-TexTM. Our Instrumental system produces results far more quickly (normally within hours as opposed to days or weeks depending on the sample under test).

Weatherproof textiles are typically plain weaves with yarns coated with a durable water repellent (DWR) finish.  Many also have a microporous or monolithic film, coating, or a bicomponent combination.  Measuring the permeability of such fabrics has historically been fraught with difficulties, with different equipment producing wildly different results – often by as much as 4-500%.

For companies where the throughput is not high enough to warrant dedicated equipment, we provide a laboratory testing service.

Our gravimetric textile permeability measurement equipment, offers a comprehensive permeability testing service and consultancy. The equipment was developed for, and is fully compliant with the detailed specifications and requirements of ISO 15496
