Draft Zambian Standard - Plastics - Film sheeting
This draft Zambian standard has been prepared by the Plastic Carrier Bags and Flat Bags Technical Working Group constituted by the Environmental Council of Zambia, in collaboration with the Zambia Bureau of Standards. This draft Zambian standard describes a method for the determination of average thickness of a sample and average thickness and yield of a roll of a plastic film and sheeting by gravimetric techniques. It was adopted due to its relevance to the Carrier bags and Flat bags standard (DZS 719). It is technically equivalent to ISO 4591 PLASTICS FILM SHEETING Determination of average thickness of a sample and average thickness and yield of a roll by gravimetric techniques (gravimetric thickness), published by the International Organization for Standardization (ISO).
