This document describes the quality grades for sorted Polypropylene (PP) waste streams as well as specific test methods laying out those properties for which the supplying party of the waste makes information available to the receiving party. Polypropylene waste quality grades are based on pre-determined sets of characteristics, taking into account sectorial and market specificities and related information needs and tests methods. The scheme provides for a division of information between "Required Data", where a statement is required, and additional "Optional Data" as agreed between the supplying and receiving party. This document does not cover the general characterization addressed in EN 15347-1.

This International Standard specifies a method for the determination of the flat crush resistance of corrugated fibreboard used in the manufacture of shipping containers. This International Standard is applicable to single-faced and single-wall (double-faced) corrugated fibreboard. This International Standard is not applicable to double-wall (double-double-faced) corrugated fibreboard and to microflute corrugated fibreboard, since the end-point of the test is not clearly defined or observable.

This document describes a test method using water immersion test for assessing the discoloration of coatings on tannic wood (oak, chestnut) by tannin staining due to wood extractives. Leachates of coated and uncoated wood are collected after the immersion procedure and their colour is compared. The colour of the coated wood before and after immersion tests is also compared.

This document defines a method of determining bulk density of solid biofuels by the use of a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described. Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results.

This document provides a methodology for calculating the carbon balance of (a) forest management unit(s) (FMU). This quantification methodology will demonstrate to what extent carbon pools in the FMU represent a net carbon sink or a net carbon source. It provides information that can be used on organizational or aggregated product levels. This calculation methodology considers: Emissions from fossil fuels or industrial processes related to forestry operations (e.g. production and distribution of fertilizers, fuels for machinery) are not included in this document. The quantity of wood entering the harvested wood products carbon pool is not included in this document. This document is intended to be used by organizations seeking to understand, commit to or contribute to climate change mitigation. These organizations can be either private or public, regardless of type or size, and located in any jurisdiction, or position within a specific value chain.

This document specifies how to calculate the greenhouse gas dynamics of a set of wood and wood-based products. It includes the greenhouse gas emissions, removals, and carbon pools for one or multiple forest management unit(s), harvested wood product(s), value chain(s), and potential displacement of emissions from alternative products replaced by wood-based products. Together these four components represent the greenhouse gas dynamics of a set of wood and wood-based products. The scope of the calculations are the organizational or an aggregated level, comprising the area of study. This document sets general requirements and overarching terminology. This document specifies the different components of a greenhouse gas dynamics calculation. This document includes information on how claims and declarations can be communicated based on this standard, both within the value chain and to customers and consumers. This document is intended to be used by organizations seeking to understand, commit to or contribute to climate change mitigation. These organizations can be either private or public, regardless of type or size, and located in any jurisdiction, or position within a specific value chain.
