Determination of GHG direct and indirect emissions based on a mass balance method at each process step for the steel industry. Definition of performance indicators will be included as well as rules for consolidation of processes at site level. The objective is the determination of a methodology to evaluate and compare the emission performance over time or between sites. Field test will be organized to compare mass balance methodology and stack measurements for assessment of direct emissions.

IWA 19:2017 provides a global framework for the sustainable management of secondary metals. The framework includes sustainability and traceability requirements for metals recovered. IWA 19:2017 guides economic operators of secondary metals value chains, including those engaged in the informal sector, in the efficient and credible implementation of improved recycling practices, in particular in emerging and developing economies.

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 c...view more
