CSA Preface
This is the first edition of CSA ISO 18135, Solid biofuels — Sampling, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 18135 (first edition, 2017-04).
This Standard describes methods for preparing sampling plans and certificates, as well as taking samples of solid biofuels, for example, from the place where the raw materials grow, from production plant, from deliveries (e.g., lorry loads, or from stock). It includes both manual and mechanical methods, and is applicable to solid biofuels that are either:
• fine (particle sizes up to about 10 mm) and regularly shaped particulate materials that can be sampled using a scoop or pipe, for example, sawdust, olive stones and wood pellets;
• coarse or irregularly shaped particulate materials (particle sizes up to about 200 mm) that can be sampled using a fork or shovel, for example, wood chips and nut shells, forest residue chips, and straw;
• baled materials, for example, baled straw or grass;
• large pieces (particle sizes above 200 mm) that are either picked manually or automatically;
• vegetable waste, fibrous waste from virgin pulp production and from production of paper from pulp that has been dewatered;
• thermally treated and densified biomass materials;
• roundwood.
This Standard is not applicable to airborne dust from solid biofuels. It may be possible to use this Standard for other solid biofuels. The methods described in this Standard may be used, for example, when the samples are to be tested for moisture content, ash content, calorific value, bulk density, durability, particle size distribution, ash melting behaviour, and chemical composition.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
