This document specifies the technical delivery requirements for

—    semi-finished products, hot formed, e.g. blooms, billets, slabs (see NOTE 1),

—    bars (see NOTE 1),

—    wire rod,

—    finished flat products, and

—    hammer or drop forgings (see NOTE 1)

manufactured from the case-hardening non-alloy or alloy steels listed in Table 3 and supplied in one of the heat-treatment conditions given for the different types of products in Table 1 and in one of the surface conditions given in Table 2.

The steels are, in general, intended for the manufacture of case-hardened machine parts.

NOTE 1       Hammer-forged semi-finished products (blooms, billets, slabs, etc.), seamless rolled rings and hammer-forged bars are covered under semi-finished products or bars and not under the term “hammer and drop forgings”.

NOTE 2       For International Standards relating to steels complying with the requirements for the chemical composition in Table 3, however, supplied in other product forms or treatment conditions than given above or intended for special applications, and for other related International Standards, see the Bibliography.

In special cases, variations in these technical delivery requirements or additions to them can form the subject of an agreement at the time of enquiry and order (see 5.2 and Annex A).

In addition to this document, the general technical delivery requirements of ISO 404 are applicable.

This procedure specifies a method for the determination of 228Ra activity in drinking waters by radium
extraction, purification and liquid scintillation counting.

This document specifies a four-cavity mould, the type С ISO mould, for the injection moulding of small tensile bars measuring ≥ 60 mm × 10 mm × 3 mm (the type CW11 test specimen in ISO 20753).

This International Standard specifies a rapid method for extraction of oil and for preparation of the methyl esters of fatty acids. The methyl esters thus obtained can be used for gas chromatography.

This International Standard is applicable to the following oilseeds: rape, sunflower, soya beans, mustard, linseed.

NOTE          Applying this rapid method to high erucic acid content rapeseed leads to an overestimation of erucic acid content by approximately a mass fraction of 1 %. This difference was observed in the study [6] and may be due to the partial extraction of the oil from the sample (yield around 70%). High content of erucic acid in triglycerides could increase their solubility in hexane because of the lipophilic effect of the carbon long-chain (C22). However, as this effect was not checked on a large set of high erucic rapeseed samples, it is not recommended to apply a correction factor to the erucic acid content when analysing high erucic acid rapeseed.

This International Standard describes simplified methods for taking samples of solid biofuels in small
scale applications and stores including preparation of sampling plans and certificates. Usually the focus
is 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 be
sampled 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 be
sampled 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 and
briquettes);
It may be possible to use this standard on other solid biofuels. The methods described in this
International 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 melting
behaviour 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 standard
is applicable ISO 18135 should be used.

This International Standard specifies the general characteristics of fibre ropes and their constituent materials. It is intended to be used in conjunction with the standards for the individual types of fibre rope, which cover the physical properties and specific requirements for that particular product type.

This International Standard also gives some information on the use of fibre ropes and also on their inspection and retirement criteria.

This International Standard does not intend to address all of the safety matters associated with its use. It is the responsibility of the user to select a rope that is fit for purpose: of the size and with the physical properties to meet the requirements of the application and to determine the applicability of regulatory limitations prior to its use.

This International Standard describes a method for the accelerated conditioning of test specimens of polyamides and copolyamides. It is applicable to grades containing more than 2 % (m/m) extractables.

The equilibrium moisture content attained by this method is close to the equilibrium moisture content obtained in standard atmosphere 23/50. The values of mechanical properties obtained after accelerated conditioning in accordance with this method may differ slightly from those obtained after conditioning in standard atmosphere 23/50.

This document establishes a system of designation for thermoplastic polyester (TP) material, which can be used as the basis for specifications. It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT), poly(ethylene naphthalate) (PEN), poly(butylene naphthalates) (PBN) and other TP-types and copolyesters of various compositions for moulding and extrusion.

The types of thermoplastic polyester are differentiated from each other by a classification system based on appropriate levels of the designatory properties:

a)     viscosity number;

b)    tensile modulus of elasticity;

and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.

This designation system is applicable to thermoplastic polyester homopolymers and copolymers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, fillers and other additives. This document does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers covered by ISO 20029.

It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20028‑2, if suitable.

In order to designate a thermoplastic polyester material to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).

This European Standard contains safety-related requirements for high pressure water jet machines with drives of all kinds (e.g. electric motor, internal combustion engine, air and hydraulic) in which pumps are used to generate pressure. This document deals with all significant hazards, hazardous situations and events arising during assembly, erection, operation and servicing relevant to high pressure water jet machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

This document is applicable to all types of fluid heating solar collectors. This European Standard specifies performance requirements for fluid heating solar collectors with respect to durability, reliability, safety and thermal performance. This European Standard includes provisions for the assessment and verification of constancy of performance to these requirements.
This document deals with the collector module and not with assemblies. This document is not applicable to those devices in which a thermal storage unit is an integral part to such an extent that the collection process cannot be separated from the storage process for making the collector thermal performance measurements.

This Technical Specification provides a method for the evaluation of the rinsing effectiveness of household clothes washing machines, washer dryers and commercial washing machines. The amount of residual linear alkylbenzene sulfonate surfactant (LAS) extracted from the unstained test swatches of the strips used in the washing performance test is determined. This is accomplished by measuring the ultraviolet (UV) light absorbance at the wavelength particular to LAS, a key ingredient of the detergent.
Assuming a fixed linear relationship between LAS amount and quantity of detergent mixture and using a concentration versus absorbance curve developed as part of this procedure, the absorbance values are then converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities. This assumption is done, because in the frame of this test it is not possible to determine the exact amount of LAS involved, even in the concentration curves, but only the amount of detergent used.
On the textiles, this linear relationship is not given, but it is nevertheless used to express the amount of LAS as determined by UV light absorbance measurements in terms of a detergent amount.
Using a concentration versus absorbance curve developed as part of this procedure, the absorbance values can then be converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities.

This International Standard specifies, for ropes of different kinds, a method of determining each of the following characteristics:

linear density;

diameter;

lay length;

braid pitch;

elongation;

breaking force.

The linear density, lay length and braid pitch are measured with the rope under a specified tension called the reference tension, as specified in Annex A.

The elongation corresponds to the measured increase in length of the rope when the tension to which it is subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum specified breaking strength of the rope.

The breaking force is the maximum force registered (or reached) during a breaking test on the test piece, carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking force values given in the tables of rope specifications are only valid when this type of testing machine is used.

When it is not possible to test the rope in full size, the method described in Annex B can be used, subject to agreement between the parties involved.

This International Standard also provides a method for measuring water repellence, lubrication and finish content, when requested by the customer.

This European Standard defines Technology Readiness Levels (TRLs). It is applicable primarily to space system hardware, although the definitions could be used in a wider domain in many cases.
The definition of the TRLs provides the conditions to be met at each level, enabling accurate TRL assessment.
