Glass with HS Test is tempered glass that is additionally heated after tempering in order to remove any glass that breaks spontaneously. The HS test identifies glass that has a high level of nickel sulphide inclusions, impurities that cause spontaneous breakage. This type of glass is suitable for hard-to-reach locations, high altitudes or rooms that require additional protection.
