DTI reviews national standard on steel bars for concrete reinforcement

Published Feb 12, 2018 04:05 pm
The Department of Trade and Industry’s Bureau of Philippine Standards (DTI-BPS) undertakes review of the Philippine National Standard (PNS) 49:2002, Steel bars for concrete reinforcement – Specification (PNS 49:2002) through the BPS Technical Committee on Steel (BPS/TC 11) Sub-Committee on Steel for Long Products (SC 01). The PNS 49:2002 specifies the requirements for deformed steel bars for concrete reinforcement. It applies to steel bars manufactured from prime billets or ingots, supplied as rolled or hot-rolled with subsequent quenching and self-tempering. “The BPS periodically reviews a PNS to ensure that the standard remains relevant and useful to its consumers. The urgent review of PNS 49 is necessary to consider global developments and subsequently assist the Philippine government, industry, and, consumers,” DTI-BPS Director Engr. James E. Empeño said. The revision of PNS 49 began on August 2017 and is expected to be finished within the year, depending on issues that will be raised and decided by the TC. The BPS Technical Committee conducted its third meeting on Jan. 25 and discussed the provisions on sampling procedures and alignment of the standard to the recent National Structural Code of the Philippines (NSCP). Conforming to the BPS Directives in developing, reviewing and promulgating a PNS, the BPS TC 11 is composed of representatives from the academe, trade and industry, consumers, professional association/s, research institution/s, government agencies, and, testing Institution/s. As the National Standards Body, the BPS is tasked to develop/ adopt, promulgate, implement and promote Philippine National Standards mandated by the RA 4109 Series of 1964.
