After studying the test results of imported Chinese canvas RMIT textile department have issued a report that the three samples of imported Chinese canvas supplied do not comply with the Australian standard AS 2001.2.18.1987
Based on these results expert opinion is that Australian canvas is far superior to the imported canvas of three leading Camper Trailer importers and based on these results the Chinese canvas is not fit for the purpose for camper trailer tents.
Conclusion – A purchaser can have complete confidence in purchasing a camper from a Guild member knowing that the canvas is Australian made and conforms to the Australian standard.
