Purpose According to the ISO 9001 standard, all the certified companies should calibrate their measuring equipment. By doing so, companies can guarantee, with rigor and quality, its measurement and use reliable data for monitoring the quality of their products. However, a metrology laboratory is not required to have an ISO 9001 certification or ISO/IEC 17025 accreditation. At this moment, there are companies with their quality management systems certified according to the ISO 9001 standard which have metrology laboratories to make internal checks of their measuring equipment. On the other hand, there are companies with ISO/IEC 17025-accredited laboratories. Finally, there are companies that have their QMS certified according to ISO 9001 and also their metrology laboratory accredited by ISO/IEC 17025. In this case the metrology laboratory must comply with the requirements of both standards. Thus, the purpose of this paper is to analyze the level of importance of the ISO 9001 and ISO/IEC 17025 standards from the perspective of a metrology laboratory. Design/methodology/approach The research methodology used to conduct this research was supported in case studies that had been carried out in nine metrology laboratories. The information was gathered based on semi-structured interviews. Findings After an analysis and discussion over the data obtained, the authors verified that the impact on customer perception is significantly positive, if the metrology laboratory is simultaneous certified and accredited. Originality/value From the laboratories perspective, the issue analyzed in this paper is of the utmost importance and the aim is to give the contribution in order to clarify this kind of organizations of which could be the best option for their context.
Frame buildings are prone to cracking because of their deformation by normal and extreme events such as temperature and earthquakes. Even though the crack widths are limited in the structural design, a cracked cover reduces the corrosion protection of reinforcing steel. Therefore, the load capacity of structures can be compromised prematurely. This paper aims to evaluate the flexo-compressive strength of deteriorated reinforced concrete (RC) elements in the corrosion process. To that end, a methodology to calculate the residual strength capacity was proposed, considering the influences of crack widths and cover width on the corrosion level—structure age relation of RC elements. The strength deteriorations caused by the concrete cracking and the steel corrosion were incorporated according to structure age. The residual strength was studied using parametric analyses, whose variables were the crack width, the cover width, the rebar diameter, and the structure age. The results showed that the cracked frame elements reduced their serviceability life by up to 62%, although their crack widths were within range recommended by the design codes (lesser than 0.30 mm). In 25 years, the corrosion effects reduce the element strength by up to 44%. This is due to the corrosion protection provided by the cracked cover becomes insignificant, reducing the initiation time. Thus, considering the corrosion deterioration can prevent strength overestimations up to 1.46 times. Additionally, according to their current state, the proposed methodology provides a practical estimation of flexo-compressive strength in corroded RC elements.
