Modern techniques underpin CHSA's new testing procedure

The Cleaning & Hygiene Suppliers Association (CHSA) is exploiting modern techniques to introduce a greater consistency to the testing procedures used as an integral part of the Manufacturing Standards Accreditation Scheme for plastic refuse sacks.

“The 'drop test' is at the heart of the accreditation scheme for plastic refuse sacks,” said Gordon Butt, the scheme's independent assessor and former trading standards officer. “Each sack is filled to a pre-defined weight, then dropped a specific height and assessed for damage. It's important the items used to achieve the weight are typical of those likely to be put in the sack and so until now manufacturers have used wet nappies in the test. We've now been able to produce purpose-made jute bags to the specified weight and scheme members are using them as part of their testing regime. This change increases the consistency and reliability of the drop test and so buyers of plastic sacks from members of the scheme can be more certain than ever that they are getting a product that is fit for purpose.”

10 sacks are tested using the drop test. If at least nine resist any damage, the batch is then considered to have passed and be suitable for the 'duty' category in question. According to the British Standards test, a batch will pass if there is damage to no more than 10% of the sacks with a split or tear greater than 50mm.

Members of the scheme use the British Standards Institute's drop test to assess if the sacks match the 'fit for purpose' specifications of light, medium, heavy and extra heavy duty. The products are then labelled according to the results of the test, so enabling buyers to be certain they are getting what they pay for. Complementing this process, Gordon Butt evaluates their testing procedures, conducts spot checks and conducts a formal annual audit.
