BS EN 12691:2018 - TC

This standard BS EN 12691:2018 - TC Tracked Changes. Flexible sheets for waterproofing. Bitumen, plastic and rubber sheets for roof waterproofing. Determination of resistance to impact is classified in these ICS categories:

• 91.100.50 Binders. Sealing materials
• 75.140 Waxes, bituminous materials and other petroleum products
• 83.140.10 Films and sheets

This European Standard specifies a test for puncture by impact on sheets for roof waterproofing.
