This International Standard describes simplified methods for taking samples of solid biofuels in smallscale applications and stores including preparation of sampling plans and certificates. Usually the focusis on stores with a size of 100 t. The standard is applicable to the following solid biofuels:- fine (up to about 10 mm nominal top size) and regularly-shaped particulate materials that can besampled using a scoop or pipe, e.g. sawdust, olive stones and wood pellets;- coarse or irregularly-shaped particulate materials (up to 200 mm nominal top size) that can besampled using a fork or shovel, e.g. wood chips, hog fuel and nut shells;- large pieces (above 200 mm nominal top size) which are picked manually (e.g. firewood andbriquettes);It may be possible to use this standard on other solid biofuels. The methods described in thisInternational Standard may be used, for example, when a sample is to be tested for moisture content,ash content, calorific value, bulk density, mechanical durability, particle size distribution, ash meltingbehaviour and chemical composition.This International Standard can be used also for applications and stores > 100 t if the involved parties,e.g. provider and consumer of a biofuel, agree with.For sampling in general, if higher precision of analytical results are needed or in doubt if this standardis applicable ISO 18135 should be used.

This part of prEN 1335:2017 applies to office work chairs. It specifies dimensions of three types of chairs as well as test methods for their determination.Annex A (informative) contains a Rationale for office chair features and comparison between current published dimensions with European anthropometric data.
