77.020 - Production of metals

This document gives specific technical guidance for the production of pure metals or their corresponding crystalline salt certified reference materials (CRMs) in accordance with the general requirements of ISO 17034. This document is only applicable to solid pure metal and crystalline salt CRMs, including candidate materials, unless otherwise noted.

This document specifies requirements for underground pipework systems used to transfer liquid fuels and their vapours at petrol filling stations. Minimum performance requirements covering fitness for purpose, safety and environmental protection are given.
This document is applicable to pipework made from thermoplastics, which can include some degree of reinforcement, and to flexible metal pipework. It does not apply to fibre reinforced thermosets, commonly referred to as glass fibre reinforced plastic (GRP), nor to rigid metals.
This document is applicable to:
-   delivery pipes from tanks to dispensers, including positive pressure, vacuum suction and siphon modes;
-   fill pipes from road tankers to tanks;
-   vapour recovery and vent pipework;
-   pipework for secondary containment;
-   fittings.
It does not apply to pipework for use with liquefied petroleum gas.

This document establishes a procedure for verifying that the manufacturer of special materials for the petroleum, petrochemical and natural gas industries has sufficient competence and experience of the relevant material grades of metal, and the necessary facilities and equipment, to manufacture these materials in the required shapes and sizes with acceptable properties according to the applicable standard, material specification and/or material data sheet specified by the purchaser.
This document is applicable to manufacturers of various materials, product forms and manufacturing processes when specified by the purchaser. This document has been established considering especially, but not exclusively:
a)    duplex stainless steel;
b)    high alloyed austenitic stainless steel;
c)    nickel-based alloys;
d)    titanium and its alloys.
This document is also applicable to the processes of induction bending and strain-hardened products.

This European Standard provides a harmonized methodology for calculating GHG emissions and GHG performance in the steel industry.
This European Standard applies to facilities producing any of the multiple products of the steel value chain. It is supported by a set of worksheets [1].
This European Standard deals with the specific aspects for the determination of GHG emissions from steel production and the assessment of emission performance. This standard is to be used in conjunction with EN 19694-1, which contains overall requirements, definitions and rules applicable to the determination of GHG emissions for energy-intensive sectors, thereby providing a common methodological approach.
EN 19694-1 and EN 19694-2 provide a harmonized method for:
a)   measuring, testing and quantifying methods for the determination of  greenhouse gas (GHG) emissions;
b)   assessing the level of GHG emissions performance of production processes over time, at production sites;
c)   the establishment and provision of reliable and accurate information of proper quality for reporting and verification purposes.
In addition, this standard provides a stepwise approach for the determination of CO2 emissions and the assessment of CO2 performance of steel facilities, providing a set of methodologies allowing for a fair and reliable assessment of the CO2 performance of each individual process along the steel production value chain.
It can be seen as a toolbox which enables the determination of CO2 emissions and the assessment of CO2 performance of steel production facilities at various levels of disaggregation, establishing a sound system for:
-   the evaluation of the global CO2 performance of a steel production facility taking its production structure into account;
-   setting a reliable basis for evaluation of the CO2 reduction potential in a facility and the contributing processes;
-   setting a basis for accurate evaluation of new technologies.
Next to the determination of the direct and indirect CO2 emissions of a steel facility, this standard has a strong focus on performance assessment which it strives to address through the following aspects:
-   assessment of CO2 impact, including process emissions: this methodology evaluates the total CO2 emission of a steel facility, with the carbon content of the waste gases burdened as CO2 to the processes giving rise to them;
-   assessment of the actual CO2 impact: this methodology evaluates the total CO2 emissions released by a steel facility, but considers waste gases exported or used in a power plant as equal to natural gas in terms of CO2 emissions;
-   carbon input CO2 performance at facility level: this methodology delivers an indicator comparing the facility performance with best practice, on the basis of the carbon input to the system;
-   CO2 performance assessment at process level: this methodology delivers a set of indicators comparing process performance with best practice at unit level. These indicators are then combined as a consolidated figure for the whole facility. This methodology also provides a theoretical assessment of the CO2 saving potential up to best practice.

This European Standard describes techniques for the manual, pulse-echo, ultrasonic testing of forgings manufactured from austenitic and austenitic-ferritic stainless steels. Mechanized scanning techniques, such as immersion testing, may be used but should be agreed between the purchaser and supplier (see Clause 4).
This part of EN 10228 applies to four types of forgings, classified according to their shape and method of production. Types 1, 2 and 3 are essentially simple shapes. Type 4 covers complex shapes.
This part of EN 10228 does not apply to:
-   closed die forgings;
-   turbine rotor and generator forgings.
Ultrasonic testing of ferritic and martensitic steel forgings is the subject of Part 3 of this European Standard.

This part of ISO 197 defines terms relating to methods of processing and heat treatment such as hot and cold working, strain hardening, annealing and partial annealing, temper, homogenizing, solution heat treatment, natural ageing and artificial ageing, quenching, and stress relieving.
