Hello, my name is John Smith. I just graduated from university and now I work in Australia. My work is related to engineering and construction, so in my spare time I often collect some national standards, hoping that these can help you.
If you don’t find the standard you need on my personal website（www.freestandardsdownload.com）, you can email me and I will try my best to help you find it. My email address is: firstname.lastname@example.org
Finally, I would like to state a few points:
1. All the content on my website is from the Internet, and the copyright belongs to the original author.
2. If the content I share violates your rights and interests, please email me and I will delete it within two days.
3. I share these contents only for study and work. They are forbidden to be used for business activities. Please purchase authentic standards.
