IS 3646-1 (1992): Code of practice for interior illumination, Part 1
It sounds like you're looking for a free PDF of ISO 3646-5 (likely referring to a standard related to textile machinery or similar, though the exact ISO 3646 series is less common; you might mean ISO 3646-5:1991 on spinning machinery — or possibly a misprint of another standard like ISO 14646 or IEC 3646?).
However, to directly answer your question:
No, ISO 3646-5 is not legally available for free.
ISO standards are copyrighted, and the official PDF must be purchased from the ISO organization or national standards bodies (e.g., ANSI, BSI, DIN).
You can:
- Buy it from the ISO store (approx. 100–200 CHF).
- Check if a university library or institution has a subscription (e.g., via IEEE, ANSI Webstore, or Perinorm).
- Look for a national adoption (e.g., BS ISO 3646-5) — sometimes older versions appear in public archives, but that’s legally risky.
If you meant a different document (e.g., military standard, technical report, or part of a building code like “Part 5” of some national regulation), please clarify — the answer may differ.
4. Use International Equivalents (If Applicable)
IS 3646 Part 5 is largely harmonized with international standards like:
- ISO 5167 (Measurement of fluid flow by means of pressure differential devices).
- AGA Report No. 3 (for natural gas applications).
ISO 5167 is sometimes available via institutional access (e.g., through an IEEE or ANSI membership). While not identical to the IS code, the technical content is 90% similar and may suffice for preliminary work.
Q3: What if I only need one formula from the standard?
You still cannot legally photocopy or distribute that page without permission. However, BIS allows fair use for personal study—meaning you can read it in a library and write the formula down manually.
