What are ASTM standards?

ASTM standards cover safety, performance, and test methods for specific product categories. For example, ASTM F963-17 applies to toys and covers design safety, small parts, flammability, and toxic substances.
In this video, I explain what ASTM standards are, and why these are crucial when importing and manufacturing products for the US market.
This is covered:
1. What are ASTM standards?
2. Examples of ASTM standards
3. Are ASTM standards mandatory?
4. CPSIA
5. Lab testing
I also explain why you should not ignore ASTM standards that are voluntary.

I have done attachments at two factories and I am saying for one was water/petroleum (astm)for more than half a year and the current one is ongoing,water purification(Hanna).
I self-issued a packet of corn starch to a water meter reader having it do up to 11 applications,so there,now if I don't buy long-term assets it might pose a problem if I don't do most of life skills early.
