PD CEN/TR 10364:2018

What is PD CEN/TR 10364- Steels and cast irons about? 

PD CEN/TR 10364 is a safety standard on steels and cast irons. 

PD CEN/TR 10364 gives guidance regarding the chemical composition controls of steels (except chrome plated products) and cast irons in respect of the European legislation, namely Directives 2011/65/EU (RoHS) [1], repealing 2002/95/EU, the Commission Delegated Directive EU 2015/863 amending Annex II to Directive 2011/65/EU [10] and 2000/53/EC (ELV) [2]. 

These Directives require the characterization of these materials for cadmium (Cd), hexavalent chromium (Cr (VI)), mercury (Hg), lead (Pb), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE), and the four phthalates DEHP, BBP DBP, and DIBP. Nevertheless, the Directives do not reflect the correspondence between these elements/compounds and the normal composition of each material concerned. In other words, for every material, there is an obligation to determine all the compounds listed, independently of the relevance of such controls. 

Who is PD CEN/TR 10364- Steels and cast irons for?  

PD CEN/TR 10364 on steels and cast irons is relevant to: 

• Mechanical engineers 
• Corrosion engineers 
• Electrothermal engineers 
• Producers of alloys and grades 
• Steel and iron industries 
• Manufacturers of steel and iron castings 
• Manufacturers of the spectrometer 

Why should you use PD CEN/TR 10364- Steels and cast irons? 

Steel and cast irons are used as construction materials and are used to make structures for buildings. 

Directive 2011/65/EU, Article 4, restricts the following substances to the maximum concentration values to the following: 

• Lead: 0,1 % 
• Mercury: 0,1 % 
• Cadmium: 0,01 % 
• Hexavalent chromium: 0,1 % 
• Polybrominated biphenyls (PBB): 0,1 % 
• Polybrominated diphenyl ethers (PBDE): 0,1 % 
• Bis(2-ethylhexyl) phthalate (DEHP): 0,1 % 
• Butyl benzyl phthalate (BBP): 0,1 % 
• Dibutyl phthalate (DBP): 0,1 % 
• Diisobutyl phthalate (DIBP): 0,1 % 

Steel and cast-iron manufacturers are often required to state/provide compliance with the Directives above and submit analytical results for each of those elements/compounds.  

Overall, PD CEN/TR 10364 is useful as it assists the user with the analytical techniques available and appropriate for the determination of both these elements below 1 μg/g as, for example, inductively coupled plasma mass spectrometry (ICP-MS), cold vapor atomic absorption spectrometry or electrothermal atomic absorption spectrometry (ETAAS).
