Japan Testing Center for Construction Materials (建材試験センター, JTCCM)

JTCCM was founded in 1963 and was designated under the Building Standards Act as a 指定性能評価機関 (designated performance evaluation body) for MLIT approvals. At its Central Laboratory in Soka it runs 防耐火試験 (fire-resistance and fire-protection tests) on large and medium wall furnaces, horizontal and beam furnaces and four-sided column furnaces. It also runs flying-brand, heat-release, non-combustibility, gas-toxicity and flame-spread tests. It evaluates 防火設備 (fire doors and shutters) and fire-protective materials for 大臣認定 (ministerial approval), and holds JNLA/MRA lab accreditation.
