Diheptyl succinate

Particle size distribution (Granulometry)

Administrative data

Endpoint:

particle size distribution (granulometry)

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is marketed or used in a non solid or granular form

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2016

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

test procedure in accordance with national standard methods

Qualifier:

no guideline followed

Principles of method if other than guideline:

Scope:
This method describes the evaluation and observation of products in terms of physical appearance.
Procedure:
(For Liquid or Molten Samples)
1. Upon receiving material samples, visually check top and bottom (on liquid products only) samples for haze, particulate matter, or discoloration.
2. If material is not perfectly clear or free of particulate matter, request a resample. Also, compare sample to a retain of the previous receipt.
3. If any doubt persists, the material is vacuum filtered through a clean Whatman #4 filter paper inserted into a clean & dry Buchner funnel. There should be no particulate matter observed on the filter paper.
4. If after resampling, the material does not meet visual clarity specification, inform the Lab Manager or Lab Supervisor and the Shift Supervisor that the material is rejected due to physical appearance.
5. If the material is rejected due to physical appearance, file the appropriate report:
a. Raw Material Non-Conformance
A Vendor Corrective Action report will be initiated and sent to the vendor for completion.
b. Finished Product/Intermediate Non-Conformance
A Non-conformance report will be initiated and sent to management for review.
Safety:
Adhere to normal safety practices. Consult MSDS prior to using chemicals.
Document Control:
All changes to documents must follow the guidelines of document control according to established change control policy, and work instructions.
