ASTM sets maximum limit of lead in zinc for making galvanized steel

Considering the negative effect of lead on the performance of galvanized steel sheets, the ASTM (the American Society for Testing and Materials) — which is an internationally recognized organization engaged in issuing international specifications for thousands of products — has introduced a limit of maximum 90 mg/kg of lead in zinc bath used for manufacturing of galvanized steel in accordance with ASTM A 653/A653M.
This limit was reached by consensus involving balloting among the ASTM technical committee members followed by a meeting held in May, and has resulted in the publication of newly revised ASTM A653/A653M.
The purpose of this important amendment to the ASTM Standard is to enhance the performance of galvanized steel as some galvanized steel manufacturers add excessive amounts of lead to the zinc bath used in the galvanizing process to obtain larger and brighter spangles, while disregarding its negative effects on the performance of the produced galvanized steel sheets.
Both theoretical studies and practical experiments have demonstrated that this addition of lead leads to darkening of the spangles over time, thereby impairing the aesthetics of the galvanized steel sheet.
Studies have also shown that adding lead to the zinc bath can cause a problem called "delayed adhesion failure" in hot-dip zinc coatings. Being immiscible with zinc, lead solidifies at the spangle boundaries to produce sites where corrosion cells form in humid climates. After some months this results in cracking and peeling of the coating when the product has been formed using sharp bending.
On the other hand, it is widely known that lead is a toxic substance with severe health risks for humans if it is used in quantities that exceed safe limits.

ICD, BBI launch global private sector platform

The Islamic Corporation for the Development of the Private Sector (ICD) and Bosna Bank International (BBI) signed a memorandum of understanding on May 16 in Jeddah. The MoU is related to a new initiative — the Global Platform for Private Sector — where the two institutions and community of like-minded financial entities can collaborate on business opportunities, exchanging market intelligence and laying a foundation for actual financial transactions within the member countries and across borders.
The signing ceremony took place in ICD’s headquarters in Jeddah and the document was signed by Ayman Sejiny, CEO of ICD, and Amer Bukvic, CEO of BBI.
Sejiny said: “ICD takes the lead in launching such a platform network to demonstrate productive applications of fintech in modern global business affairs, to help reduce financial transaction costs for its member banks, leasing companies and micro-finance institutions and to upgrade the advisory services that ICD offers to its partners across the Islamic developmental network.”
Bukvic added: “We welcome the initiative and we’re happy to be among the first entities to sign the MoU with ICD. Such a platform would open opportunities for Bosnia and Herzegovina, BBI bank and other partners once implemented, and will most certainly facilitate investment across borders. This will extend our efforts already expressed by organizing international events in the capital of Bosnia and Herzegovina, such as the Sarajevo Business Forum and the Sarajevo Halal Fair.”

 

Bosna Bank International (BBI) d.d. Sarajevo is the first bank, both in Bosnia-Herzegovina and Southeast Europe, to operate in accordance with Islamic finance principles. BBI offers several types of financial services to retail and corporate clients through its business based on ethical principles and partnership. Shariah compliance is ensured by the BBI Shariah board with members of this board being prestigious local and international experts.
The Global Platform for Private Sector will be a cloud-based, next-generation, full-featured networking and fulfillment platform hosted by ICD for the benefit of its network of 88 financial institutions and 12 leasing companies worldwide. One major goal of this online platform is the sharing of investment, advisory, sukuk, financing and other deals in an environment of common Islamic values.
ICD is a multilateral development financial institution and is part of the Islamic Development Bank (IsDB) Group. It was established in November 1999 to support the economic development of its member countries through the provision of finance for private sector projects, promoting competition and entrepreneurship, providing advisory services to the governments and private companies and encouraging cross-border investments.
ICD has an authorized capital of $4 billion. Currently, the shareholders of ICD are the IsDB, 54 Islamic countries and five public financial institutions.
