What is BS 3338-21 – Tin and tin alloys about?
BS 3338-21 standard is a part of the BS 3338 series that discusses the determination of high cadmium content of soft solders for sampling and analysis of tin and tin alloys. The properties of tin make it ideal for use as a coating. Owing to the low melting point of tin, and because it readily alloys with most other metals, tin coatings can easily be produced by immersing a suitably prepared metal object in a bath of molten tin.
BS 3338-21 describes a method for the determination of cadmium in tin base solder alloys containing 10 % to 30 % of cadmium and with reproducibility of 0.15 % of the cadmium present.
Who is BS 3338-21 – Tin and tin alloys for?
BS 3338-21 on tin alloys applies to:
- Manufacturer of tin products
- Quality testing personnel
- Chemical engineers
Why should you use BS 3338-21 – Tin and tin alloys?
The properties of tin make it ideal for use as a coating. Owing to the low melting point of tin, and because it readily alloys with most other metals, tin coatings can easily be produced by immersing a suitably prepared metal object in a bath of molten tin.
BS 3338-21 provides you with the method which helps you in the determination of the high cadmium content of soft solders. BS 3338-21 also provides the sampling procedure in which the sample for analysis is taken by one of the suitable procedures described in BS 3338-12. These procedures and methods will help you in the manufacturing of tin alloys in a standardized manner.
With BS 3338-21 you can be ensured that the products consistently meet and exceed quality assurance targets.
