As part of our ISO 17025 laboratory accreditation and as a requirement from one of our safety agency annual accreditations, we have had to control consumables such as the cheesecloth and tissue paper that we purchase for testing to IEC 60950-1 and its national derivative standards.
We have been purchasing our cheesecloth and tissue paper from suppliers, who, to give a short answer, were “pre-approved” by one of our accrediting bodies. There were a series of verification tests that had to be conducted, I suppose in accordance with an ISO standard. I don’t have the contacts where we purchased the cheesecloth and tissue paper, but I can look them up and supply them to you. I believe they are American companies, not from the UK.

I was preferably looking for a link to a Product Safety test equipment website which sold critical consumables to give us greater confidence what we're buying is compliant. FWIW I'm aware that this approach will cost more than purchasing from local department stores.

I buy mine at Ace Hardware which is a nationwide chain in the US. Tissue paper is available at any card or party store that carries gift wrapping paper year round. Both of these items are very common and can be found at most department or box stores. Good luck.

The definition of the tissue paper in 60950-1 is: WRAPPING TISSUE: soft and strong, lightweight wrapping paper of grammage generally between 12 g/m2 and 30 g/m2, primarily intended for protective packaging of delicate articles and for gift wrapping [ISO 4046-4:2002, definition 4.215] And the definition of the cheesecloth is: CHEESECLOTH: bleached cotton cloth of approximately 40 g/m2.
