Diseño de Procedimientos Técnicos del Laboratorio de Ensayos en Materiales del CONAVI, según los Requisitos de la Norma INTE-ISO/IEC 17025:2005

Abstract

This document was developed in order to design all technical procedures for eight laboratory tests involving hydraulic concrete and twelve tests related to stone aggregate, within the CONAVI Material Testing Laboratory, and following both the guidelines from the accreditation process before the Costa Rican Accreditation Entity (ECA) and the guidelines from the norm INTE-ISO/IEC 17025:2005. Also there was developed a technical instructive for laboratory equipment control. Within technical documentation for each test, there were developed tests instructive, registers and technical forms, according to INTECO and ASTM. Furthermore there were designed registers and spreadsheets in order to verify the equipment used in all related tests according to all established specifications. Besides, there were design registers to control the use of ovens, scales, testing machines and neoprene pads. Additionally, there was design a test methods for concrete (temperature, slump, unit weight and compressive strength) and stone aggregate (unit weight, weathering resistance, material finer than N°200 mesh and density, gravity and fine and coarse absorption) validation plan.
