This document specifies a test method for determining the comparative compression shear strength of adhesive bonds and solid wood at both ambient temperature and elevated temperature. The maximum load of the test pieces at ambient temperature and after exposure to a defined elevated temperature for a specified duration of time is evaluated. It is applicable to adhesives used in load bearing timber structures and to other wood adhesives.

It is suitable for assessing the influence of elevated temperatures on the compression shear strength of the adhesive bond.

This method is intended primarily to obtain performance data for the influence of elevated temperatures on the behaviour of adhesive bonds. It can be used for the assessment of adhesives for load bearing timber structures and as well for the assessment of non load-bearing wood adhesives with respect to their suitability for forming bonds in defined climatic environments, at elevated temperatures.

This method is not intended to provide data for structural design, and does not necessarily represent the performance of the bonded member in service.

This document specifies the general principles of a method, using an inclined-tube falling-ball viscometer, for determining the viscosity of polymers and resins in the liquid emulsified or dispersed state. It is intended for application to liquids over a viscosity measurement range of 0,6 mPa·s to 250 000 mPa s (temperature range −20 °C to +120 °C) for which the shear stress and shear rate are proportional, i.e. the viscosity is independent of the shear rate. This ideal behaviour is commonly known as Newtonian behaviour. If a liquid differs significantly from this behaviour, different results can be obtained with the different balls of a falling-ball viscometer or from viscometers with different geometries, such as capillary and rotational viscometers.

This International Standard specifies methods for determining the deterioration of plastics due to the action of fungi and bacteria and soil microorganisms. The aim is not to determine the biodegradability of plastics.

The type and extent of deterioration may be determined by

a) visual examination

and/or

b) changes in mass

and/or

c) changes in other physical properties.

The tests are applicable to all plastics that have an even surface and that can thus be easily cleaned. The exceptions are porous materials, such as plastic foams.

This International Standard uses the same test fungi as IEC 60068-2-10. The IEC-method, which uses so-called "assembled specimens", calls for inoculation of the specimens with a spore suspension, incubation of the inoculated specimens and assessment of the fungal growth as well as any physical attack on the specimens.

The volume of testing and the test strains used will depend on the application envisaged for the plastic. These parameters should therefore be agreed upon before the tests and should be stated in the test report.

This document specifies three methods for the determination of the density of non-cellular plastics in the form of void-free moulded or extruded objects, as well as powders, flakes and granules.

Method A: Immersion method, for solid plastics (except for powders) in void-free form.

Method B: Liquid pyknometer method, for particles, powders, flakes, granules or small pieces of finished parts.

Method C: Titration method, for plastics in any void-free form.

NOTE This document is applicable to pellets as long as they are void-free. Density is frequently used to follow variations in physical structure or composition of plastic materials. Density might also be useful in assessing the uniformity of samples or specimens. Often, the density of plastic materials will depend upon the choice of specimen preparation method. When this is the case, precise details of the specimen preparation method will have to be included in the appropriate material specification. This note is applicable to all three methods.

1.1 General

This European Standard applies to heating boilers including safety devices up to a nominal heat output of 500 kW which are designed for the burning of solid fuels only and are operated according to the instructions supplied with the boiler and misuse reasonably foreseeable by the manufacturer.

This European Standard applies also for solid fuel boilers up to 70 kW nominal heat output taking the combustion air from outside the building.

This European Standard deals with significant hazards, hazardous situations and events relevant to heating boilers used as intended and under the conditions specified in the technical documentation of the boiler (see Clause 4).

The boilers may operate under natural draught or forced draught. The fuel feed may work manually or automatically. The boilers may operate in non-condensing operation or condensing operation.

NOTE This European Standard deals with boilers which are within the scope of the Machinery Directive 2006/42/EC or outside of the scope of the Machinery Directive 2006/42/EC (manual stoked natural draught boiler).

This European Standard contains requirements and test methods for safety, combustion performance, operating characteristics, marking and maintenance of heating boilers. It also covers all external equipment that influences the safety systems (e.g. back burning safety device, integral fuel hopper).

This European Standard covers only boilers that include burners as a unit. The standard applies to the combination of a boiler body with a solid fuel burner according to EN 15270 as a unit only when the whole unit is tested in accordance with this European Standard.

Heating boilers in accordance with this European Standard are designed for central heating installations where the heat carrier is water and the maximum allowable temperature is 110 °C, and which can operate at a maximum allowable operating pressure of 6 bars. For heating boilers with a built-in or attached water heater (storage or continuous flow heater), this European Standard only applies to those parts of the water heater which are necessarily subject to the operating conditions of the heating boiler (heating part).

This European Standard does not apply to:

— heating boilers and other heating appliances which are also designed for the direct heating of the place of installation, also according to the European regulation 2015/1185/EU;

— cooking appliances;

— the design and construction of external fuel storage and transportation devices prior to the safety devices of the boiler;

— manual stoked straw bale boilers;

— CHP appliances.

This European Standard specifies the necessary terminology for solid fuel heating boilers, the control and safety related requirements, the design requirements, the technical heating requirements (considering the environmental requirements) and testing, as well as the marking requirements.

This European Standard is not applicable to heating boilers which are tested before the date of its publication as an EN (European Standard).

This part of ISO 14708 specifies requirements that are applicable to those ACTIVE IMPLANTABLE MEDICAL DEVICES that are intended to treat hearing impairment via electrical stimulation of the auditory pathways. Devices which treat hearing impairment via means other than electrical stimulation are not covered by this part of ISO 14708.

The tests that are specified in this part of ISO 14708 are type tests and are to be carried out on samples of a device to show compliance.

This part of ISO 14708 is also applicable to NON-IMPLANTABLE PARTS and accessories of the devices (see NOTE).

The electrical characteristics of the IMPLANTABLE PART are determined by either the appropriate method detailed in this part of ISO 14708 or by any other method demonstrated to have an accuracy equal to, or better than, the method specified. In the case of dispute, the method detailed in this part of ISO 14708 applies.

NOTE A device that is commonly referred to as an active implantable medical device can in fact be a single device, a combination of devices, or a combination of a device or devices and one or more accessories. Not all of these parts are required to be either partially or totally implantable, this standard specifies those requirements of NON-IMPLANTABLE PARTS and accessories which could affect the safety or performance of the implantable part.

1.1 This International Standard specifies the design, performance and testing requirements for "Cargo Stopper" air cargo restraint accessories with a 22 250 N (5 000 lbf) rated load capacity, to be used in conjunction with air cargo restraint straps meeting ISO 16049-1 (TSO/ETSO ̶ C172), or air cargo restraint slings meeting ISO 20291-1, with the same rated load.

1.2 Cargo Stopper devices designed to this International Standard are intended to be used in either of the following typical instances:

(a) to ensure restraint / tie-down of a piece of cargo that does not lend itself to either direct hooking of tie-down straps or passing a strap around without risk of slippage. A common example is long shaped cargo items with a narrow cross-section, whether or not overhanging from the pallet, individual or in bundles, e.g. pipes or beams. See 7.4 in ISO 16049-2, Cargo Restraint Straps – Utilization Guidelines.

(b) to restrain cargo smaller than the pallet net’s mesh, or identified as "piercing", presenting a hazard to the aircraft in the event of it being released during flight.

(c) when a crate containing cargo, even though its cross-section is large enough to be directly tied-down with the pallet net or restraint straps, contains or may contain a heavy item, e.g. piece of machinery, shaft, or similar with a cross-section lower than the pallet net’s mesh size.

NOTE Such "hidden" items have been known to break free from insufficiently strong crates when subjected to in-flight accelerations, then pass due to their small size through the net mesh restraining the crate and be released into the cargo compartment.

(d) to assist in tying-down odd shaped cargo pieces where it is difficult or not allowed to directly attach tie-down straps or pass them around the load in an effective manner.

1.3 Cargo Stopper devices are used as part of cargo restraint arrangements that must meet the regulatory airworthiness requirements. Accordingly, their design and performance must be substantiated as specified in this International Standard in order to meet regulatory requirements and obtain TSO-C202 approval.

This document specifies the procedure for the determination of total shrinkage of concrete specimens in drying conditions.

NOTE 1 Possible shrinkage or length changes occurring before 24 h of age, and which may have significant amplitude and/or consequences, e.g. for high performance concrete and/or in case of restraint, may need to be measured according to a complementary procedure not covered by the present standard.

NOTE 2 Information on a simplified procedure for the determination of autogenous shrinkage is given in Annex A.

The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.
