Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 77-1994 "lead brass hub stick" (formerly GB/T 4428-1984).
Compared with this standard YS/T 77-1994, the main changes are as follows.
--- Standard name from "lead brass rods hub" to "syringe needle holder with lead brass rod";
--- Increased HPb58-2, HPb58-3, HPb59-2, HPb59-3, HPb60-2, HPb60-3, HPb62-3 grades;
--- Increasing the product did not note fillet requirements;
--- On the rod length or multiple length to allow deviation from the "20mm", revised as "15mm";
Straightness --- bar from "per meter of not more than 10mm", changed to "not more than 5mm per meter";
--- Twisting of the rod from the "per meter of not more than 18 °", changed to "no more than 300mm per 1 °, the largest supplier of 5000mm length
Should not exceed the total twist of 15 ° ";
--- Product Elongation rate "δ10≥15%", adjust "δ10≥10%";
--- Revised Batch products;
--- Increasing the contract (or purchase order) content provisions.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
