Preparing for ISO 105 testing: from method to instrument setup

The TNG1029 Crockmeter, TNG1027 WashTrue Washing Fastness Tester, TNG1025 Scorch Tester, and TNG1034 Perspiration Tester / Perspirometer are all compliant with the ISO 105 standard for colour fastness testing.

Confirming the Method Code

Preparing for ISO 105 testing: from method to instrument setup - laboratory test illustration

Before procurement, it is essential to confirm the method code associated with the testing requirements. ISO 105 encompasses a series of test methods for evaluating the colour fastness of textiles. Each method is designed for specific types of fastness, such as rubbing, washing, perspiration, and sublimation. For instance, ISO 105-B01 is used for rubbing fastness, while ISO 105-C06 is for washing fastness. Confirming the exact method code ensures that the selected instrument aligns with the required test protocol.

Identifying the Required Measuring Range

Each instrument has a specific measuring range that must be matched to the test requirements. The TNG1029 Crockmeter, for example, is designed for rubbing fastness testing and features a rubbing head of 16 mm and a vertical pressure of 9N±10%. These specifications ensure that the test conditions are consistent with ISO 105-B01, which requires a defined rubbing force and contact area. Similarly, the TNG1027 WashTrue Washing Fastness Tester has a temperature setting range of 0°C to 95°C and a heating rate of 1.5±0.5℃/min, which are critical for simulating the washing conditions specified in ISO 105-C06.

Checking the Published Specification Table

The published specifications for each instrument must be cross-referenced with the ISO 105 standard For compliance testing. The TNG1025 Scorch Tester (Sublimation Fastness Tester) includes standard accessories such as insulation cotton and optional accessories like heat-insulating asbestos sheets, which are necessary for accurate sublimation testing as per ISO 105-D02. The TNG1034 Perspiration Tester / Perspirometer is designed to meet AATCC 15, 106, and 107 standards for perspiration, water, and sea water testing, respectively. These specifications ensure that the instrument can accurately simulate the conditions described in the relevant parts of ISO 105.

Requesting a Quotation

Once the method code, measuring range, and specifications have been verified, the next step is to request a quotation. Ensure that the quotation includes the exact model numbers (TNG1029, TNG1027, TNG1025, TNG1034) and their corresponding specifications. This ensures that the procurement process is aligned with the required testing standards and that the selected instruments are capable of delivering accurate and reliable results.

Editorial note. This application note summarises the published scope of the standard and our documented model data. Configuration requirements vary between standard editions, and instruments support a method only with the appropriate fixtures and accessories. Please confirm the required configuration against the applicable edition of the standard before ordering; conformity of a given test result also depends on the specimen and the procedure followed.
