Account Management
I am having trouble logging into my account. How can I fix this?
Ensure your login email and password are entered correctly and that your keyboard's CAPS Lock is turned off. If credentials are correct but you still cannot log in, clear your browser cache/cookies or switch to an updated web browser (such as Google Chrome or Microsoft Edge).
I forgot my password. How do I recover my account?
To reset your account password, click the "Forgot your password?" link on the store sign-in page. Enter your registered email address, and an automated password recovery link will be sent to your inbox immediately.
Codes & Standards
Are PDF documents from e-Standard protected with Digital Rights Management (DRM)?
No. All PDF standards downloaded from e-Standard Store are 100% DRM-free. You can freely copy text, print hard copies, store, and view your purchased PDF documents across all your devices without restrictive plugins or license locks.
Are technical standards delivered in Adobe Acrobat PDF format only?
Yes. All technical standards, engineering codes, and specifications available on the e-Standard Store are supplied in electronic Adobe Acrobat PDF format for universal desktop and mobile compatibility.
Can I purchase historical or redline versions of standards?
Yes. We supply historical standards, withdrawn revisions, and redline comparative documents. If a specific historical version is not listed in our search index, please submit a request to customer support.
What should I do if I cannot find a specific document on your site?
First, check our Search Help guide to ensure correct document numbers and keywords. If the standard remains unlisted, contact our support team with the document designation, and we will source it for you.
What is a DRM-protected document?
A Digital Rights Management (DRM) protected PDF restricts user actions—such as printing, copying text, or opening files on multiple computers—to enforce copyright. Note: e-Standard Store provides DRM-free PDF files for maximum usability.
What software do I need to view Portable Document Format (PDF) files?
All standards are delivered in standard Portable Document Format (PDF). You can open and read them using any standard PDF viewer, including free software like Adobe Acrobat Reader, web browsers, or mobile PDF applications.

How quickly will I receive my ordered PDF document?
All standard PDF files are processed promptly upon payment completion. Your document download link will be dispatched to your registered email address, typically within 1 hour of order confirmation.
Why don't I see a download button on the website after payment?
Documents are delivered directly to your registered account email rather than hosted as a temporary web browser download button. Check your inbox for the delivery email or contact online support for priority handling.
Why haven't I received my PDF order email after several hours?
If your order email is delayed, common causes include:
• The email address entered during checkout contained a typo.
• Your email account inbox is full.
• Automated spam/junk filters blocked the message attachment.

Payments & Billing
Are my credit card payments secure on e-Standard Store?
Yes. All payment processing uses encrypted SSL protocols. In the event of unauthorized billing charges, consumer protection policies allow you to dispute claims directly through your credit card issuer.
Why did my credit card fail with a "Do Not Honor" error?
A "Do Not Honor" transaction error is generated directly by your credit card issuing bank for fraud prevention. Please contact your card issuer to clear international online purchasing restrictions before re-attempting checkout.
How do I resolve an "IP address format is incorrect for IPv6" error?
Our payment processing gateway requires standard IPv4 protocol verification. If your Internet Service Provider uses IPv6, switch your internet connection (e.g., mobile hotspot) or contact support for a direct payment link.
Why is the charge on my statement slightly different from the website total?
e-Standard Store does not charge extra fees. Small statement discrepancies occur when your issuing bank applies international cross-border transaction fees or currency exchange rate adjustments.
Why does my bank statement display a different merchant name or RMB currency?
Billing descriptors on credit card statements can vary because transactions are routed through specialized global merchant payment gateways to ensure secure cross-border processing.
What payment methods are accepted on e-Standard Store?
We accept major credit cards (Visa and MasterCard), Bitcoin, Trustpay (European bank transfers), and Dotpay (Poland bank transfers).
Why was I charged a foreign transaction fee on my credit card?
Foreign Transaction Fees (typically 2% to 5%) are assessed directly by your credit card bank when purchasing from international online merchants or converting non-native currencies.
Why does the checkout system keep rejecting my credit card?
Credit card declines are enforced by card issuers for security. Verify that your billing address and phone number match your official card records exactly, or contact your bank to authorize international e-commerce orders.
