What did a Svanen approval on a toilet mean?
The Svanen approval wasn’t just an environmental validation, but also a quality assurance. Because the tests were that extensive, many other toilet systems on the market didn’t stand a chance at meeting the criteria. The tests were performed at an appointed, neutral test facility. The most noteworthy controls were:
• Material - It was made sure that it was sealed tightly, mechanical and electric components, ventilation and smell.
• Function - An amount of waste (urine and feces) was added, equal to that of four people at permanent use. That’s 5 liters of urine, 1 liter of feces and 100 grams of toilet paper a day. This was done under a long period of time in order to examine the end product. There were norms for what was allowed to remain in form of bacteria and nutrient salts.
• The end product - Was controlled in regards to thermo tolerant coliform bacteria, pH, Kjeldahl nitrogen, smell and consistency.
• Demands on instructions - The toilet was installed and cared for in accordance to our included instructions and guidelines.
