Rarely. Public libraries seldom carry technical standards. Try a university engineering library.
Many national libraries (e.g., British Library, Library of Congress) keep physical copies of IEC standards. You can:
: It specifies tolerances for diameter, ultimate tensile stress (UTS), and elongation. Testing Methods
IEC standards are revenue sources for the IEC, which reinvests in developing new standards. Therefore, no legal, free, full-text PDF of IEC 60888 exists for public download. Most search results claiming “free PDF” fall into three dangerous categories:
It mandates specific values for tensile strength , elongation (typically 2.5% to 3.0%), and dimensional tolerances (e.g., ±0.05 mm to ±0.07 mm).
