Mechanical vibration — Measurement and evaluation of machine vibration — Part 21: Horizontal axis wind turbines |
This document provides information about the measurement and evaluation of the mechanical vibration of wind turbines and their components. The working principle of wind turbines covered by this document is described in annex B.
On account of the great influence which the place of installation and type of mechanical drive train can have on the vibration magnitude of all wind turbine components, it is necessary to divide the wind turbines into two groups:
group 1: horizontal axis wind turbine installations with generators coupled to the rotor via a gearbox;
group 2: horizontal axis wind turbine installations with generators coupled to the rotor without a gearbox (direct drive).
This part of ISO 20816 applies to group 1 and group 2 wind turbines. It applies to horizontal axis wind turbines with rated generator outputs exceeding 200 kW and the following design and operation characteristics:
a) installation onshore or off the coast (offshore);
b) installation on supporting systems (tower and foundation) made of steel and concrete;
c) horizontal-axis rotor with several rotor blades;
d) rotor bearing separate from or integrated into the gearbox or into the generator;
e) generator direct coupled (gearless) or driven via gearbox;
f) generators of the synchronous or asynchronous type;
g) generators with only a fixed pole number or which are pole-changeable for speed adjustment;
h) permanent magnet or electrical excited induction generator with inner or outer rotor;
i) power output control by rotor blade angle control (pitch adjustment – individual or collective);
j) nacelle with active yaw system to align to wind direction.
This document recommends zones for evaluating the vibration at continuous load operation. However, in most cases these evaluation zone boundaries might not be suitable for the early detection of faults. Annex A presents evaluation zone boundaries based on vibration data from thousands of wind turbines with rated generator output up to 5 MW. They can be helpful in facilitating discussion between users and manufacturers.
The evaluation criteria contained in this standard mainly serve to ensure a reliable, safe long-term operation of the wind turbine and its components. It is intended to standardize measurements, to assist in their evaluation and to make possible a comparative evaluation of the vibration measured in wind turbines and their components. In addition, recommendations are given for the determination of limit values for operation.
Although the type and implementation of broad-band vibration monitoring for wind turbines is addressed, this document does not apply to diagnostics or fault detection by condition monitoring of wind turbines.
The evaluation of the balance quality of the slowly turning wind turbine rotor, which requires special measurements and analysis, is not covered by this document.
This document does not apply to the evaluation of torsional vibration in the drive train. Although coupled lateral and torsional vibration of tower and drive train can affect the amplitudes of the defined vibration characteristics, diagnosis of this kind of vibration source is not feasible by the described measurement methods described in this document. For general design verification purposes and for specific fault diagnosis, special measurements are required which are beyond the scope of this document.
This part of ISO 20816 also does not apply to acceptance measurements on gearboxes and generators in the manufacturer's test facility.
This document does not apply to measurements of shaft displacement, due to the small number of turbines equipped with such measurements.

ISO 17828:2015 defines a method of determining bulk density of solid biofuels by the use of a standard measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 100 mm.
Bulk density is not an absolute value; therefore, conditions for its determination have to be standardized in order to gain comparative measuring results.
NOTE Bulk density of solid biofuels is subject to variation due to several factors such as vibration, shock, pressure, biodegradation, drying, and wetting. Measured bulk density can therefore deviate from actual conditions during transportation, storage, or transhipment.

Solid biofuels — Determination of calorific value |
ISO 18125:2017 specifies a method for the determination of the gross calorific value of a solid biofuel at constant volume and at the reference temperature 25 °C in a bomb calorimeter calibrated by combustion of certified benzoic acid.
The result obtained is the gross calorific value of the analysis sample at constant volume with all the water of the combustion products as liquid water. In practice, biofuels are burned at constant (atmospheric) pressure and the water is either not condensed (removed as vapour with the flue gases) or condensed. Under both conditions, the operative heat of combustion to be used is the net calorific value of the fuel at constant pressure. The net calorific value at constant volume may also be used; formulae are given for calculating both values.
General principles and procedures for the calibrations and the biofuel experiments are presented in the main text, whereas those pertaining to the use of a particular type of calorimetric instrument are described in Annexes A to C. Annex D contains checklists for performing calibration and fuel experiments using specified types of calorimeters. Annex E gives examples to illustrate some of the calculations.

ISO 18134-3:2015 describes the method of determining the moisture in the analysis test sample by drying in an oven. It is intended to be used for general analysis samples in accordance with EN 14780. The method described in this part of ISO 18134-3:2015 is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis).
Since biofuels in small particle size are very hygroscopic, their moisture content will change with humidity in the atmosphere and therefore, the moisture of the test portion is determined simultaneously with determination of for example calorific value, carbon content, and nitrogen content.
NOTE The term moisture content when used with biomass materials can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which can evaporate when determining the moisture content by oven drying (see References [1] and [2]).

NOTE The term moisture content when used with biomass materials can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which can evaporate when determining the moisture content by oven drying (see References [1] and [2]).

Solid Biofuels — Sampling |
ISO 18135:2017 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.
ISO 18135:2017 is not applicable to airborne dust from solid biofuels. It may be possible to use this document for other solid biofuels.
The methods described in this document 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.

Solid biofuels — Safe handling and storage of solid biofuel pellets in commercial and industrial applications |
This document provides principles and requirements for safe handling and storage of solid biofuels pellets in commercial and industrial applications. This document is using a risk-based approach to determine what safety measures should be considered.
Facilities with a storage capacity <100 t are covered by ISO 20023. Generally, for end-user facilities with a storage capacity of <1 000 t, ISO 20023 could also be applicable if storage principle and facility complexity is in-line with the objectives of ISO 20023.
This document covers the handling and storage process of pellets in the following applications:
— at a pellet production plant from the outlet of the cooler unit until loaded for transportation;
— at a commercial distributor from the receiving station until loaded for transportation; and
— at an industrial end-user from the receiving station until fed into the fuel preparation or combustion process.
Although unloading and loading of e.g. vessels, trains or trucks are included in the operational envelops defined above, the safety aspect of the transportation itself is beyond the scope of this document.
This document also gives specific guidance on detection and suppression systems and preparatory measures to enable safe and efficient firefighting operations. Guidance on the management of fire and explosion incidents is also specified.
