any of one or more products (ISO 14050:2009, 3.2) from the same unit process (3.4.1), but which is not the object of the assessment
Co-product and product have the same status and are used for identification of several distinguishable flows of products from the same unit process. Where one of two or more co-products is the object of assessment of the EPD (3.1.1), this is normally considered the product and the other output(s) (ISO 14040:2006, 3.25) as the co-product(s). Where one of the co-products is an input (ISO 14040:2006, 3.21) to a process (ISO 14040:2006, 3.11), this is normally considered as a product input. From co-product and product, waste (3.3.11) is the only output to be distinguished as a non-product.
ISO 14040:2006, 3.10, modified — The definition has been clarified relative to the object of assessment and Note 1 to entry has been added.
